- Dr. Harry Wells: Her name is Dr. Light, small-time thief on my Earth until exposed to the dark matter from the Particle Accelerator and became a meta-human with the ability to derive power from starlight.
- Cisco Ramon: Oh, very cool.
- Dr. Harry Wells: Stars having a temperature of 5,300 degree kelvin and a blinding luminosity, I would say, "Not very cool at all."
- Cisco Ramon: You know, our Dr. Wells may have been evil, but you're just a dick.
- Joe West: How is he still alive? How are you still alive?
- Dr. Harry Wells: Well, I don't know. Because you missed?
- Barry Allen: Hey, I'm tryin' to keep him from shooting you. You're not helpin'.
- Barry Allen: We do what Dr. Wells said. We use her to lure Zoom here, end this once and for all.
- Jay Garrick: You can't be serious.
- Barry Allen: More breachers are gonna come. More innocent people may die. I can't let this happen anymore.
- Jay Garrick: You're making a mistake. Okay, Zoom is a nightmare you can't wake up from.
- Barry Allen: I've already had my worst nightmare. His name was Reverse-Flash. I spent a long time being afraid of him. I'm not gonna be afraid anymore.
- Patty Spivot: Hey, Barr, did you hear I was right about King Shark?
- Cisco Ramon: King Shark? Nice name. I like her.
- Patty Spivot: Yeah. Yeah, King Shark almost ate The Flash.
- Barry Allen: Oh, well, nah, I'm sure The Flash had it handled.
- Cisco Ramon: For real?
- Barry Allen: Stop, all right? I was gonna ask her out, and then a man-shark tried to eat me, and then Dr. Wells, the sequel, showed up.
- Cisco Ramon: Okay, can we not use the name "Dr. Wells?" I'm just gonna call him "Harry."
- Caitlin Snow: You've coffee on your Earth, right?
- Jay Garrick: I think coffee's the one constant thing in the multiverse.
- Dr. Harry Wells: You cannot reason with someone under Zoom's influence, and now a man is dead because of you, Garrick. This whole thing is because of you. He doubts himself because of you, but believe me, Barry can do what you could not. Barry can stop Zoom.
- Jay Garrick: I spent two years hunting Zoom.
- Dr. Harry Wells: Wrong! Zoom hunted you! You spent the last two years of your life running, running, running from Zoom.
- Jay Garrick: Zoom would have killed me just like he will kill Barry if you lead him down this path!
- Dr. Harry Wells: No, because he is not like you. Barry runs towards danger, not from it, because Barry's not a coward.
- Iris West: You look just like him.
- Dr. Harry Wells: I'm guessing my counterpart did something to offend her as well?
- Cisco Ramon: Her fiancé died because of him.
- Barry Allen: You think this is easy for me? The guy in there looks, moves, sounds exactly like the guy that drove a knife through my mother's heart. I have to resist the urge to kill him. I'm trying to get past that, okay? You shooting him, that's... that's not helping.
- Dr. Harry Wells: [harshly] Try again!
- Barry Allen: Yo.
- Cisco Ramon: I'm sorry, it's not...
- Dr. Harry Wells: Again!
- Cisco Ramon: I can't control it.
- Dr. Harry Wells: Because you're afraid.
- Cisco Ramon: I'm telling you I don't know how it works! I can't just make it happen!
- Dr. Harry Wells: I'm telling you, yes, you can!
- Dr. Light: Never killed anyone before, but it's not murder if it's your double, right?
- Linda Park: Why are you doing this?
- Dr. Light: It's the only way that I can stay alive.
