Grant Gustin: Barry Allen, The Flash

Quotes 

• Barry Allen : We have to wait how long before we can use the meta-human cure?

  Cisco Ramon : Not even that long.

  Iris West-Allen : Cisco.

  Cisco Ramon : [snapping his fingers]  It's gonna go by like that.

  Iris West-Allen : Cisco.

  Cisco Ramon : 29 days.

  Nora West-Allen : A month?

  Cisco Ramon : I know, right? Just one, teeny, tiny month until we stop Cicada's purge. You know, historically speaking, this is way faster than we've ever stopped a big bad, so...

• Barry Allen : 52 times?

  Nora West-Allen : 53, if you include now.

  Barry Allen : That's... a lot.

  Nora West-Allen : What was I supposed to do, let one of them die?

  Barry Allen : The thing is, Nora, there are consequences to time travel.

  Nora West-Allen : Oh, I know.

  Barry Allen : No, you don't. Not like I do. Let me show you something. Imagine this coffee cup is the space/time continuum.

  [as he vibrates the mug, a piece breaks off] 

  Barry Allen : Whenever you go back in time, it breaks. Now, you can try and reset the timeline, try and fix it, but no matter how hard you try, it's never gonna be exactly how it was. It seems like things worked out this time, but that's not always gonna be true, and it's impossible to know how these changes are gonna unfold; the ripples you'll cause, whose life you're gonna affect. No one can do that.

  Nora West-Allen : No one?

  Barry Allen : No one. We're not gods, Nora. We've just been given extraordinary abilities.

• Barry Allen : Sherloque was right. One hour, it's cooked.

  [seeing everyone's looks] 

  Barry Allen : Something happen while I was gone?

• Barry Allen : Nora, you need to stay here.

  Nora West-Allen : You... you don't want my help?

  Barry Allen : I just... I got this one this time.

  Nora West-Allen : Are you sure that now is a good time to go? I mean, I just mean the city will be Flash-less, and an hour is a long time to be without the Flash.

  Barry Allen : The city is not gonna be Flash-less. It'll have XS.

  Nora West-Allen : Yeah, but what about the time you had to spend 24 hours in the Pipeline cell, and Weather Witch and Silver Ghost stole that A.R.G.U.S. car...

  Barry Allen : And you stopped 'em, without me.

  Nora West-Allen : But, what... with what happened to mom because of Cicada...

  Barry Allen : Nora, Iris is fine. And this is the key to stopping Cicada. I gotta go. If anything happens, just do what I've trained you to do. Slow down and think clearly.

  Nora West-Allen : Yeah.

  Barry Allen : I trust you; you just gotta trust yourself.

• Iris West-Allen : You want him to go into the Speed Force for a month and then, what, come out the same day that he left?

  Sherloque Wells : Oh, no, no, I'm not saying you manipulate time. I'm saying you manipulate dark matter. So, very simple. It's simple chemistry, right? When you are synthesizing a compound, you use a... commodity, uh, substrate, uh...

  Caitlin Snow : A catalyst?

  Sherloque Wells : Catalyst, right. And the most effective catalyst you can use when synthesizing a compound that negates dark matter is superluminal particles.

  Nora West-Allen : Tachyons.

  Sherloque Wells : Trés bien. Tachyons, and the place where tachyons are the most dense?

  Barry Allen : The Speed Force.

  Sherloque Wells : And voilà.

  Caitlin Snow : That might actually work.

  Cisco Ramon : Yeah, it will. It'll be like nuking it in a pan-dimensional microwave. Nice work.

  Sherloque Wells : I know.

  Iris West-Allen : So, how much time would this save?

  Caitlin Snow : From 29 days down to... sixty minutes.

  Cisco Ramon : Yeah, it's gonna be faster.
