Barry Allen: Iris, it's not like I wanted to leave you. I had to put on a brave face, for everyone. But it was killing me inside. And I think part of why I didn't talk it through with you is I was afraid. I was afraid that you would tell me to stay. And I wouldn't have been strong enough not to.
Iris West: Barry, how do you know what I'm going to say if you don't ask me? I am here to help you, especially when everything seems lost. But you have to let me.
Barry Allen: But sometimes it's not about us. Or the team. Sometimes the weight of the whole city falls on my shoulders, and it's up to me to carry it. I'm the Flash.
Iris West: See, that's what you don't get. When I put this ring on my finger, it wasn't just about you or me anymore. It's about us. You are not the Flash, Barry. We are.
