in which everyone knows Erik is Peter's father, except Erik
Peter: Hey, did you get a chance to look at my essay?
Erik: I did, and was very impressed. Excellent work, Peter.
Peter: Cool! Thanks, Dad.
Peter: …Why is everyone staring at me?
Raven: You just called Erik ‘Dad.’ You said 'Thanks, Dad.’
Peter: What?? No I didn’t. I said 'thanks, man.’
Erik: Peter, do you see me as a father figure?
Peter: No! If anything, I see you as a bother-figure, because you’re always bothering me.
Scott: Hey! Show your father some respect.
Peter: *this close to losing it* I didn’t call him dad!!
