First of all, ages mean little in a place like this. Just ask the Weasleys. And I only knew you for a short time as a child but that doesn't mean I didn't care for you and I'm bound to care as an adult.
What you need to remember is, that isn't the Puck you know. And it isn't me at all. Puck came from a time long before that, before they ever even gave Beth up for adoption. Maybe he would have made those choices but chances are, he wouldn't have because he's done a lot of growing up since he's been here. They both have. Quinn isn't the same person either but I still can't bring myself to talk to her.
As for the woman with my face, yeah. It's creepy, believe me. You'll run into that a lot here, though. Freddie's best friend is a Bohemian version of him and I really can't sit and watch him do very anti-Freddie things. You learn to deal with that.
