Robin: God, I wish last night never happened.
Barney: I don't.
Robin: What do you mean?
Barney: What if this whole thing isn't the whole story of how we made a horrible mistake and ruined our relationships? What if it's the story of how we got back together?
Robin: Okay, I'm gonna ask you one last time: is this what you want?
Barney: It's what we both want. Why else are we rushing to tell them what we did, on a boat? That is a terrible idea.
Robin: Barney, we tried this, and we failed! Why try again?
Barney: Because I haven't stopped thinking about you, and you haven't stopped thinking about me.
Robin: I'm such a mess. Why do you even like me?
Barney: I guess because you're as messed up as I am.
