Mercedes: Look Quinn I could never see myself being into a guy like Puck, especially since he's your baby's daddy but something just happened between us.
Quinn: I say go for it.
Quinn: Look, I screwed up by letting Puck get me pregnant. He's an idiot and his mother won't let me eat bacon. I'm stuck living with him right now but at least if you guys are dating I won't have to spend so much time listening to his insane theories on how Super Mario Brothers changed civilization. But you do realize he's using you and your popularity so he won't get tossed in a dumpster.
Mercedes: I know he's using me and in a way it's almost better. I'm not you. I've never had a guy like me for anything. But now I'm such a steaming mug of hot chocolate that one of the studliest guys in school wants to use me to harvest some mojo.
Quinn: I just don't want you getting hurt.
Mercedes: I know what this is. My hearts safe.
Quinn: Oh I'm not worried about your heart. I might be okay with this but not even Puck is going to be able to call off Santana.
