When I first saw him, all I could see was Eobard Thawne. But when I saw him, when I really saw Harry for who he was, I became his friend. He became mine.

Cisco

Crisis of infinite Wells.

Nash

He's probably out there looking for another body right now, like a red-eyed, pissed off Voldemort.

Cisco

It was my fault. She only did what I taught her to do. It was my fault.

Nash

You think that Nash and I are limited by our emotions. But you're wrong. They give us our strength and we can use them to overcome anything, including you. That's your greatest flaw Thawne. Metas are the ones with limits, not people. Not me. And not Nash.

Barry

Thawne: You were an awful father to her.
Barry: I miss my daughter every day. But I'm done letting that give you power over me.

Barry: You want Nash, you're gonna have to go through me.
Thawne: Aren't you a glutton for punishment? Always there to bear witness to the death of someone you're trying to desperately save.

The Flash isn't supposed to have limits, Iris.

Barry

You know what I found out about Artificial Speed Forces? Thawne built one, and that's it. And I doubt he's gonna tell us, seeing how he's Linda Blaired our pal Nash and you know, he kinda wants to murder the hell out of us.

Cisco

Barry: I held her in my arms. I watched her die all over again. The Speed Force is dead because of me, because of my choices. I just wanted to save everyone, to save you.
Clone Iris: And you did. Barry none of this is your fault.
Barry: Now I won't be able to save anyone. What am I supposed to do without my speed?
Clone Iris: Maybe this is for the best.
Barry: What?
Clone Iris: Everything happens for a reason, right? Maybe you weren't supposed to be The Flash forever. I mean, don't you think that after everything the Speed Force has put you through, all the pain, all the heartache, all the death, don't you think you deserve a real life? Barry, all the world's problems on your shoulders, that shouldn't have been your burden to bear.
Barry: You're serious?
Clone Iris: I am. This could be our chance, to have a normal life, start a family. You deserve to be happy just like everyone else. Don't you want that?

Iris: Barry calls me his lightning rod. He used to say he could find me anywhere in the universe.
Eva: Seems like there's nothing he wouldn't do for you.

Speed Force: Barry Allen, we forgive you. You did the right thing. You saved our universe. You never could have foreseen what that cost. You only have a few steps left before we're gone from you entirely, but I know you will use them well. The lightning chose you and it was the best decision that we, I ever made. You showed us the greatest force of all. I love you. I love you. I love you, my beautiful, beautiful boy.
Barry: Mom, Mom don't go.

The Flash Quotes

Nora: NO SCHRAP, SHERLOQUE! Sorry for the language, Mom.
Iris: It's okay.
