- Kara Danvers: [on what her friends and family brought into her life] Guys, you've been with me from the second I became Supergirl. In my best moments and especially my worst moments. That means the world to me.
- Lena Luthor: Kara Danvers is Supergirl.
- Kara Danvers: Yeah.
- Lena Luthor: I can't believe I was fooled by a pair of glasses.
- Kara Danvers: Don't worry. A lot of people are.
- Lena Luthor: Let me guess. You're here to tell me once again that I should forgive you. Or maybe that I shouldn't work with my brother?
- Kara Danvers: Not this time. I recognize that I made a mistake in hiding my identity from you for so long. But the past is the past, and I can't change it. Forgive me or not, that's your choice. Just like it's your choice to work with Lex. I'm done blaming myself for your bad decisions.
- Lena Luthor: Then why are you here?
- Kara Danvers: To tell you that from now on you're accountable for your own actions. If you decide to forgive me, I will be there for you. But if you continue to work with Lex, if you go through with whatever it is the two of you are planning, I will do everything in my power to stop you. Just like I would any other villain.
- Kara Danvers: It doesn't matter when I tell Lena the truth. It always makes things worse. I think I've been too scared to admit it to myself, but I think Lena would be better off if she and I were never friends.
- Mxyzptlk: Is that the world you want to see?
- Kara Danvers: No. But please show me anyway.
- Kara Danvers: The Lena in this timeline might never forgive me. She might even hate me. You know what? You know what? If Sam stops her from going down a dark path, I can live with that.
- Mxyzptlk: Except you literally can't.
- Kara Danvers: What do you mean?
- [he snaps, and she watches the sky turn green]
- Kara Danvers: Oh, my god. This is the night Agent Liberty poisoned the air with kryptonite.
- Mxyzptlk: Uh, you know what? Maybe we should shut this off, huh?
- Kara Danvers: No, no, no. Lena saved me the first time. She might hate me, but she'll save me again.
- Mxyzptlk: She wants to, but she'll never make it in time.
- [Kara watches her heartbeat flatline, and the scene changes to Alex at Kara's grave]
- Alex Danvers: Hey, Kara. I'm sorry I missed Thanksgiving. We're just... we so lost without you. I... am so lost without you.
- Samantha Arias: So, Kara is Supergirl?
- Lena Luthor: Yeah, I know. My head's kind of spinning. When you were Reign, and I made kryptonite to stop you... y-you know, in response well, Supergirl was so horrible. And then Kara was the same. She was so kind and supportive. But it made me think, which was the real Kara? And if the real Kara thought I was a villain... then maybe that's all I really am.
- Kara Danvers: [watching with Mxy] No, Lena, no. How could you ever think that?
- Samantha Arias: Lena, you made kryptonite to split me from Reign and to save my life. You were never the villain. You were always the hero.
- Lena Luthor: Thank you. I really needed to hear that.
- Mon-El: My mother and the Luthors, they betrayed Lena for their own selfish reasons. They wanted to take advantage of her. You lied to protect her. Because she's your friend. I know Lena's hurting right now, but once she understands that, she'll forgive you.
- Kara Danvers: I hope you're right. But I don't think I'll ever be able to forgive myself.
- Mon-El: You know it's okay to mess up, right? No matter how many mistakes I've made, you've always forgiven me. You should know that you deserve the same compassion that you show others.
- Supergirl: Every morning when I wake up... I imagine this moment. The moment where being Supergirl gets someone I love killed. And I have to push that fear so far down... or I... I can't get out of bed. But now, here... here it is. My greatest fear, just staring me right in the face. I have to save Lena. I... I have to, but if I tell the world who I am, then I put everyone else I love at even greater risk. Alex, J'onn, James, you. What if one of you gets hurt?
- Winn Schott: Don't worry about the rest of us, okay? We're gonna be fine. No, Lena is the one that needs your help right now. We can take care of ourselves. Because you taught us how.
- Kara Danvers: Was that Mon-El?
- Mxyzptlk: Yes.
- Kara Danvers: So he didn't go back to the future?
- Mxyzptlk: Nope.
- Kara Danvers: Ha! Of course. If we didn't defeat Pestilence, then he would have been there with us...
- Mxyzptlk: Uh-huh.
- Kara Danvers: ...when we went to Sam's mom's house. Can you... can you snap me in there? I wanna get his perspective.
- Mxyzptlk: I never understood what you saw in him.
- Kara Danvers: Beam me up, Mxy.
- Mxyzptlk: You don't have a catchphrase? We'll work on that. "Girl power"? No.
- Lena Luthor: My friend came to me. She was alone and afraid. I had to do something.
- Supergirl: That feeling of needing to protect your friend, no matter what the world thinks... I understand that more than you know. You once told me Kara Danvers was your hero.
- Lena Luthor: I never told you that. I told...
- Supergirl: It's me, Lena. I've always been Kara.
- Lena Luthor: Kara, how could you?
- Supergirl: I'm sorry I didn't tell you sooner.
- Lena Luthor: Three weeks ago, I found out that Sam, one of my closest friends, was a homicidal Kryptonian. I went through that terror alone. I risked my life day after day for weeks because I believed that I was the only one who could be trusted to protect her, to save her. I could have used your help. I would have used your help, if you'd bothered to tell me the truth before now. If you trusted me, then, I wouldn't have had to go through that danger alone!
- Supergirl: I'm so sorry, but I thought I was protecting you. But now, we can... we can move past it and work as partners.
- Lena Luthor: You expect me to be your partner after this? When all you've done is prove to me that you can't be trusted at all?
- Supergirl: [seeing the Worldkillers' solar eclipse begin] Oh, no.
- Lena Luthor: To be honest, I didn't have much faith in politicians to begin with. I just don't think any of them can be trusted.
- [Kara looks around, realizing she's in her memory]
- Lena Luthor: Don't look so scandalized, Kara. You know how cynical I can be.
- [seeing her look]
- Lena Luthor: Is everything okay?
- Kara Danvers: You shouldn't have to be so cynical. You're good and righteous, and... and the tragedy is, the world has made you cynical because you've been betrayed so many times. By your mother, by your brother... and now, by me.
- Lena Luthor: What are you talking about?
- Kara Danvers: [moving to sit next to her] I'm not who you think I am. I'm Supergirl.
- [taking off her glasses]
- Kara Danvers: I never meant to deceive you. I just didn't know how to tell you.
- [an alarm sounds]
- Kara Danvers: You stay here. I'll deal with this.
- [she speeds away; after a brief fight, she returns]
- Supergirl: Lena?
- Kara Danvers: [watching with Mxy in her lot] What happened? Where'd she go?
- Mxyzptlk: Ah. Events are unfolding differently now. Oh, boy. Um, I need to catch up.
- [snapping]
- Mxyzptlk: Ah, there she is.
- Kara Danvers: She went to Metropolis.
- [seeing who Lena is with]
- Kara Danvers: Oh, my god. She went to see Sam.
- Mxyzptlk: So, three years of friendship. Where did it go wrong?
- [she picks up an empty popcorn bucket; he snaps, and she jumps as it magically fills up]
- Kara Danvers: Well...
- Mxyzptlk: Uh-huh?
- Kara Danvers: When Lena told me that she knew I was Supergirl, she was furious.
- Mxyzptlk: Yeah.
- Kara Danvers: She said I made a fool out of her.
- Mxyzptlk: Uh-huh.
- Kara Danvers: She was humiliated.
- Kara Danvers: Okay, uh, before we do this, Mxy, I need your word that if thing go sideways, you'll put it all back to normal.
- Mxyzptlk: I am court-ordered to do so.
- ["beeping" her nose]
- Mxyzptlk: Boop. Now, no shade to the Super Friends, but it tends to work better when it's just me and the subject. So, do you two have any plans?
- Alex Danvers: No, I don't think so.
- J'onn J'onzz: No. No, we were just gonna...
- Kara Danvers: [Mxy snaps, and they vanish] What... where did they go?
- Mxyzptlk: Oh... they're in their happy place.
- Alex Danvers: [transition to them playing paintball] Magic rules!
- J'onn J'onzz: Game on, Danvers!
- Kara Danvers: What could I possibly need your help for?
- [Mxy snaps his fingers]
- Lena Luthor: [on the TV] I killed my brother for you, for our friends! Don't you understand what you've done?
- Mxyzptlk: Your best friend thinks that she is your enemy. And the worst part... it's your fault. You hid the truth from her. You let her find out from that sadist, Lex, and now, you think, she could be capable of anything.
- Kara Danvers: What's your point?
- Mxyzptlk: My point, toots, is this.
- Kara Danvers: [he walks across the furniture] Careful.
- Mxyzptlk: I am offering you a do-over. Hmm? I can send you back in time. Wouldn't you like to be able to tell Lena that you're Supergirl on your own terms? Wouldn't you like to see... what the world would look like if you controlled the narrative?
- Defense Attorney: And what is Supergirl's real name?
- Lena Luthor: I hardly see how that's relevant.
- Defense Attorney: Citizens have the right to know the name of the officer that arrests them. If Supergirl is gonna act like judge and jury, we should know her name, as well.
- Lena Luthor: [glancing at Kara] I plead the Fifth.
- Winn Schott: I can't trace the signal.
- Alex Danvers: Well, look, some lone wolf shouldn't have the resources to thwart our trackers.
- J'onn J'onzz: He must have powerful help.
- Winn Schott: Yeah, help spelled L-E-X.
- Alex Danvers: If that's the case, then we are never gonna find her.
- Winn Schott: [Supergirl crumples the table in frustration and storms off] Stay here. I got it.
- Kara Danvers: This was right before Lena and I really became friends. See, she's about to say...
- Kara Danvers, Lena Luthor: I didn't come here to make friends.
- Kara Danvers: She didn't wanna let anyone in, and then when she did, I made the mistake of not letting her in, too. This time, I'm gonna do it right.
- J'onn J'onzz: When Lena first came to National City, to take over at L-Corp, Lex tried to have her assassinated. He failed, but she was seriously injured in the attack.
- Alex Danvers: And she disappeared for two years. When she came back, everybody said that she was... different, that she had changed.
- Kelly Olsen: The trauma, the loneliness... it drove her mad.
- Winn Schott: She retaliated against Lex, killed him. Took half of National City along with her. Now she rules what's left with an iron fist. Reign is her enforcer.
- Dreamer: And Brainy, too. She captured him. Aligned him. Now he has no emotions, and does whatever Lena tells him to.
- Supergirl: Oh, no. Oh, this, this... I have made a terrible mistake. This world is my responsibility.
- Mxyzptlk: Okay. So we're looking for a moment where you made your best friend feel like a big, dumb idiot, yeah?
- Kara Danvers: In so many words.
- Mxyzptlk: Okay. Well, we have an embarrassment of riches.
- Kara Danvers: Mxy, can you please take this seriously?
- Mxyzptlk: "Take it serious". Because every party needs a pooper. And that's why we invited Kara.
- Kara Danvers: Really?
- Mxyzptlk: If we're going to take the fun out of stuff, let's really do it.
- Kara Danvers: In the original version of events, Lena helped me and the DEO to fight the Worldkillers.
- Mxyzptlk: Okay.
- Kara Danvers: I know she's upset right now, but she's gonna help us.
- Mxyzptlk: Welcome to the bizarro version where she does not help the DEO, right... right here.
- Kara Danvers: What?
- [seeing herself fighting Reign]
- Kara Danvers: Oh, god! No. If Lena doesn't help us fight the Worldkillers, then...
- Mxyzptlk: Yep.
- Kara Danvers: [he starts fast-forwarding] Wait, wait, wait. Wait! You're skipping a lot!
- Mxyzptlk: This is all exposition, so much exposition.
- Kara Danvers: [watching a memory with Lena] Ugh. This is awful! I'm awful!
- Mxyzptlk: You're awful.
- [she looks at him indignantly]
- Mxyzptlk: I was just agreeing with you. I would never say that.
- Mxyzptlk: But now I can't use any of my powers except to help those whom I have wronged.
- Alex Danvers: Oh, how sad for you.
- Alex Danvers: Yes. A tragedy of Shakespearean proportions.
- Kara Danvers: My dual identities made Lena think that she couldn't trust either side of me. I was a hypocrite.
- Mxyzptlk: Okay, so, when exactly did this kryptonite-fueled tete-a-tete happen?
- Kara Danvers: Ah... it was... it was, uh, just after we found out that Lena was housing Reign.
- Supergirl: [on the tape] Lena, the Worldkillers are coming. We have to get you someplace...
- Kara Danvers: Mmm, skip forward.
- Mxyzptlk: Skip.
- [he fast-forwards through various scenes]
- Kara Danvers: See, there? This fight...
- Mxyzptlk: Mm-hmm.
- Kara Danvers: ...is what I'm trying to avoid.
- Mxyzptlk: Okay.
- Kara Danvers: So, go back.
- [he rewinds, and she watches herself asking James to investigate Lena's kryptonite stock]
- Kara Danvers: Ah, I never should have done that. Um... yeah, it has to be before this.
- Mxyzptlk: Yeah, hang on, before.
- Kara Danvers: We have to go back further. Here!
- Mxyzptlk: Yep.
- Lena Luthor: My friend came to me. She was alone and afraid. I had to do something.
- Supergirl: I need you to level with me. Do you have any more kryptonite?
- Kara Danvers: This is it. This is the moment that Lena started to distrust Supergirl. This is when I have to tell her.
- Kara Danvers: I forgot.
- Mxyzptlk: Yeah.
- Kara Danvers: The Worldkillers started an eclipse that day.
- Mxyzptlk: Mm-hmm. So, you forgot the... forgot the eclipse, and then you also forgot the kryptonite bomb. You know what we're not gonna do? We're not gonna rely on your memory anymore for maybe, like, big, important details.
- [she scoffs indignantly]
- Mxyzptlk: Just saying. We got to try something else.
- Kara Danvers: All right, so, how does this work?
- Mxyzptlk: I will show you relevant parts of your life. You'll tell me when to pause, I will snap...
- [pantomiming in demonstration]
- Mxyzptlk: ...like thus, sending you back. You will change history. Once you have confronted Lena, you will come back, we will watch from your loft and the safety of your couch. If you are comfortable with the domino effect...
- [he claps, and an old-school film projector appears]
- Mxyzptlk: ...I will then snap again, at which point it will become reality.
- Mxyzptlk: I get it. You don't trust me. Okay, but how's this? Ready?
- [offering a tape recorder]
- Mxyzptlk: Now, by Fifth Dimensional law, I am required to give you this recording of me saying my name backwards, in case you ever need to banish me to my Fifth Dimension, which I know that you...
- [taking it, Kara immediately presses "play"]
- Mxyzptlk: [on the recording] Kltpzyxm.
- [he vanishes]
- Lena Luthor: [on the TV] I'm not a villain. You shouldn't have treated me like one.
- J'onn J'onzz: [entering] Hey, girls. What's going on?
- Kara Danvers: Oh, okay.
- Mxyzptlk: Ah.
- Kara Danvers: Let's go to before Mercy attacks.
- Mxyzptlk: Right there?
- Kara Danvers: Mm-hmm.
- Mxyzptlk: You sure?
- Kara Danvers: Yes.
- Mxyzptlk: Don't mess it up.
- Alex Danvers: Okay, I'm sorry, I'm confused. This is your all-powerful Fifth-Dimensional stalker?
- Kara Danvers: No. I don't know who this is.
- Mxyzptlk: I am Mr. Mxyzptlk, just as I'm sure that you, Kara Danvers, are Suuuuuuu...
- Kara Danvers: [pulling him inside] Ah, get in here!
- Mxyzptlk: Thank you so much. I can't just come in anymore. I have to be invited.
- Kara Danvers: If you are Mxy, then why do you look like this?
- Mxyzptlk: Okay, I only took on that other form and sophisticated accent to impress you. But it worked. You caught me.
- [he snaps his fingers]
- Mxyzptlk: [on the TV] You tricked me.
- Supergirl: No, I followed the rules. You say your name backwards, you go back to the Fifth Dimension, no questions asked.
- Mxyzptlk: Ah, I miss that hair. I really, really do.
- J'onn J'onzz: You're not seriously thinking of doing this, are you?
- Kara Danvers: What if I *could* change things? If I told Lena that I was Supergirl before Lex, maybe she would have reacted differently. I mean, isn't that worth a try?
- Alex Danvers: Changing history to save a friendship? Kara, I don't... I don't know.
- Kara Danvers: This is changing history to *save* history, 'cause Lex and Lena are planning something horrible, and we are no closer to finding out what that is. And when the fight comes... I don't know if I have what it takes to stop her.
- Kara Danvers: Tell me who you are and what you want, now.
- [Mxy snaps his fingers, and on her TV, she sees the memory of their first encounter]
- Mxyzptlk: I'm your one true love, your soul mate, your one true pairing, as the kids say. My name is Mxyzptlk, and I love you Kara, Zor-El.
- Kara Danvers: Okay. If you...
- [gasping as she sees him sitting Indian-style on her kitchen island]
- Alex Danvers: Oh, come on.
- J'onn J'onzz: Kara, are you sure you can trust Mxy?
- Kara Danvers: No. But the tape recorder worked. I... I could always just use it to get him to go away.
- Alex Danvers: All right, listen to me. If you really think that this is your best chance to set things right with Lena before she hurts somebody... then do it.
- Kara Danvers: Okay. Uh... how do I do this? Um...
- Mxyzptlk: [materializing in and climbing out of her fridge] Thank Zook you changed your mind. Yes, I'm still working on eavesdropping. That's a problem.
- Lena Luthor: You don't know the first thing about pain. But I do. I can show you, make you feel what I feel.
- Supergirl: I won't fight you, Lena.
- Lena Luthor: Then you'll die screaming.
- Kara Danvers: Holy cow. That was the most emotionally draining experience of my life, and let me tell you, I've had some doozies.
- Supergirl: I finally told Lena I'm Supergirl.
- Mon-El: Wow. How, uh... how did she take it?
- Supergirl: Not well. And I don't blame her. I mean, I'm supposed to be her best friend, and I... I lied and betrayed her just like everyone else in her life has. So, what do I do?
- Mon-El: You know, Lena and I have a lot in common. We've both been betrayed by our own families. And when the people who are supposed to love you the most let you down, it just makes you feel so... so vulnerable, you know?
- Kara Danvers: I've always been so afraid to reveal my identity to the world, but look, it saved Lena. Maybe... just maybe, this... this is the timeline to stick with. Let's...
- Mxyzptlk: I see why you would think that, but, um, maybe we should skip ahead to the ending?
- Kara Danvers: Oh, no. What happens?
- Reporter: [Mxy snaps] After Supergirl's identity was released to the world, Agent Liberty and his followers targeted each of Supergirl's friends, including her former employer Cat Grant...
- Kara Danvers: Oh, no, no, no. No.
- Reporter: ...one by one. There were no survivors.
- Kara Danvers: All right, all right, enough. Stop. Stop. I don't wanna see anymore. Please turn it off, please.
- Supergirl: [entering a dystopian reality] What happened? Where are we?
- Mxyzptlk: Where your loft used to be.
- Supergirl: [picking up a charred, framed picture] You know what? No, thanks. Nope. I don't need to see it.
- Mxyzptlk: Yeah.
- Supergirl: Can you just snap us out of here?
- Mxyzptlk: Yep. With pleasure.
- [as he snaps, nothing happens]
- Supergirl: [he continues trying] What's happening?
- Mxyzptlk: I can't feel the Fifth Dimension at all. Without my powers...
- Supergirl: We're stuck here?
- Otis Graves: [after Kara reveals her identity as Supergirl] Good stuff, my dude! But we should kill the hostages anyway, right?
- Ben Lockwood: No. No, we keep our word. Send them the location.
- Patricia Arias: Sam, no, this isn't you! I know you're in there. I know you are!
- Supergirl: [Reign grabs Patricia] No.
- Reign: You really thought you could stop me, Supergirl? You can't even protect this one pathetic human.
- Patricia Arias: Oh, Sam...
- Lena Luthor: [zapping her in the back] But I can. Because this is the tool I use to bring Reign out and bury you down. Okay, come back to us, Sam.
- Reign: [labored breathing] I will kill... you all!
- Lena Luthor: Why are you trusting me with such a big secret? You barely know me.
- Kara Danvers: Because I know that what you want more than anything is to do good. And I know it's hard for you to trust people, but I need you to know now, without a doubt, I trust you. My cousin, your brother, they got it wrong. Imagine what we could do together. A Luthor and a Super, working together as a team.
- Lena Luthor: If we were partners, we could change the world.
- Supergirl: You did it! You saved Sam.
- Lena Luthor: Yeah, and I did it without kryptonite.
- Supergirl: [catching Lena as she's hit in the back by a heat vision beam] No!
- Reign: Fool! I am a Worldkiller. And I cannot be stopped!
- Ben Lockwood: You knew my father, Peter Lockwood?
- Lena Luthor: You're Ben. We were sourcing our steel from his factory, and then he abruptly closed it.
- Ben Lockwood: No, he-he didn't close it. He converted it to a church.
- Lena Luthor: The Cult of Rao. I'm so sorry, Ben. If Supergirl and I can do anything to help your father...
- Ben Lockwood: You can't. Because he's dead. My father, my wife, my only son, George, they jumped off a roof because they believed... that she would save them. And she didn't.
- Lena Luthor: I'm so sorry, Ben. If there's anything I can do to help...
- Ben Lockwood: Well, you could tell me who Supergirl is. She parades around as a god, but she hides in plain sight as a human. Ms. Luthor, if... if people knew who she was, if they knew that she bought a coffee in the morning or that she rode the bus or that she worked a job just like the rest of us, then they would stop worshipping her. So, I have to know who she is. And you are going to tell me.
- Lena Luthor: It's never gonna happen. And if you have issues with the Cult of Rao, I suggest you take it up with Coville.
- Ben Lockwood: Oh, uh...
- [opening a van door, revealing Coville tied up inside]
- Ben Lockwood: I already have.
- Dreamer: Look who I found.
- Alex Danvers: [hugging] Oh, Kara, thank god you're here.
- J'onn J'onzz: Who's this?
- Supergirl: Oh, this is my friend, Mxyzptlk.
- Mon-El: Mxyzptlk?
- Supergirl: Yeah.
- Mon-El: What, you thought with a new face, we wouldn't recognize the same old you? This is the guy who tried to make Kara marry him.
- Supergirl: It's fine, Mon-El. Because he is reformed... and he's actually helping me.
- Mxyzptlk: Uh, no... you know what? No, Mon-El is right. Okay? It was despicable of me to pursue a woman who so clearly was not interested in me from the get-go. I misread the room, and I'm gonna be better. It's tough to be an imp. And I'm gonna try for the rest of my days. So, maybe we can let the past be the past, huh?
- News Anchor #2: Powerful testimonies in the trial of Lillian Luthor today. But will they be undercut by Lena Luthor's refusal to give up Supergirl's identity?
- Thomas Coville: Well, nothing so trifling as the laws of man could stand in the way of Supergirl and Lena Luthor's divine victories!
- [cheers from the crowd]
- Thomas Coville: For I once thought that true power was the Kryptonian walking amongst us, but that power is nothing compared to the might of a Kryptonian paired with a Luthor!
- [more cheers]
- Kara Danvers: [watching with Mxy] This is incredible. The last time Lillian was on trial, the whole world suspected Lena of working with her, but having Supergirl as a partner... it gives Lena the credibility her last name never could.
- Mxyzptlk: [animatedly, a la an old-time radio broadcast] Only months after publicly declaring their partnership, the formidable duo of Supergirl and Lena Luthor have already cleaned up National City's criminal element. This pair is literally unstoppable! Not to mention fashionable, after Lena convinced Supergirl to cut the hair of steel, and gave her a new suit to boot. But their next adversary is Lillian Luthor herself, and this time, their battleground is a courtroom. Emotions. Drama. Will they persevere?
- Kara Danvers: Lena was never angry about hypocrisy. She was angry because I never shared my identity with her in the first place.
- Mxyzptlk: Uh-huh.
- Kara Danvers: So, you know what that means? We have to go back to the very beginning.
- Mxyzptlk: Give me a date and a time, I will make it so.
- Kara Danvers: Um, let me think
- Mxyzptlk: Hang on a second.
- [showing her "Mxyflyx" on his laptop]
- Mxyzptlk: It's just, it's buffering. This happens sometimes. It's the interdimensional WiFi. You know what? It doesn't even matter. I've got your entire friendship on BetaMyx.
