Amethyst: What?! You had no idea!? Ho! This is, like, my entire existence! You want to pretend that none of this ever happened! You think I'm just a big mistake!
Pearl (gasps) No, no. Amethyst, you're not the mistake. You're just the by-product of a... big mistake. ...No, that's not- I... I just never thought of this as you. None of this is your fault. You didn't build this place. I... I'm sorry, Amethyst. I hope you can forgive me. You're the one good thing that came out of this mess. I always thought you were proud of that.
