Barry and Wells in “Unfinished Business”

Barry

You said it. Everything's different here. There's a guy creating metahumans, innocent people, because I changed the timeline. It's on me.

Wells

Yeah, well, I think I know a thing or two about what that feels like. I keep making mistakes. I make mistakes, then I want to make up for my mistakes, then I just make more mistakes. Next thing I know, I have a daughter that won't even speak to me.

Barry

How do we keep from messing things up when all we want to do is help?

Wells

I dunno. But you did once tell me that you have to trust that in the long run, the decisions you make are the right ones.

Barry

Yep.

Wells

I was always too good at forgiving myself, Allen. And you were never good enough.
