The Flash, Season 2

Barry:
Can't stop thinking about my dad's doppelganger. Seeing him, knowing that he's out there, that should've made it easier. It doesn't. It just made me miss him even more.

Iris:
I can't even imagine how hard that must have been.

Barry:
We just won. We just beat Zoom. Why does it feel like I just lost?

Iris:
Because you've lost a lot in your life, Barry. More than most. But... maybe you and me, seeing where this thing goes, maybe that can give you something for a change.

Barry:
That's all I've ever wanted to hear you say. And I wish that I was in a place where I could try that with you. But I feel so hollowed out inside right now. I feel more broken than I've ever felt in my life. If I'm ever gonna be worth anything to you, I need to fix what's wrong with me. I need to find some... some peace.

Iris:
Barry, listen to me. You waited for me for years. You let me get to a place where this is possible. So I am telling you: I am gonna do the same thing for you. Wherever you need to go, whatever you need to do... do it. And when you get back, I'll be here.

Barry:
Okay.

Iris:
I love you, Barry.

[Barry and Iris kiss.]

Barry:
I love you, too. And I always will.
