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

Cisco: You're not Nash.
Eobard: Hello, Cisco.

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.

Barry: You with me?
Wally: Always.

The Flash Quotes

One mystery I cannot figure out is why some people come into our lives and why some people go. Others become a part of you. Some friendships feel like they'll last forever and others end far too soon. Not every friendship is meant to last forever. What does last forever is the pain when that person is gone.

Barry

Barry is lucky to have you on his side, Joe.
