Ooooh, I really like the idea of Lucy and Leicester being friends after having gotten into a debate. She would have definitely scored points with Lei by not backing down and holding a debate with him about whatever not important topic, especially if she didn't get all OMG YOU'RE JUST WRONG OKAY D: about it. AND he would really appreciate having someone he could gush (not his own word choice, ofc) over animals with.
Leicester would definitely know Max, then. He would prefer to not have problems with people he's friends with or likes (that's just a whole lot of unnecessary drama), so I can't see him having an issue with Max. It might be possible that Lei's known Max since childhood as well? I can sort of see Max being the kind of person Leicester would have made friends with when he's younger without any issues, so he's still friends with him, but if they had met when they were older they probably wouldn't have become friends? ASK:A I JUST THOUGHT OF SOMETHING. So, this is true for Hailey as well, but if Max did know/had been friends with him pre-Hogwarts, that would also have been pre-werewolf, which...might be very, very interesting to figure out.
Haha, I'm not really sure what Leicester would think of Addy taking his picture. I don't think it would make him all D: but at the same time he would be more likely to frown at her like he didn't understand why she was doing that then stop and strike a pose. >.>
I've been thinking about Leicester joining dueling club, which is reeeally likely, so Cel and he could know each other from that! And Lei wouldn't be intimidated by her or anything like that, so I could definitely see them getting along fairly well.
I agree about random interactions for Theo and Lei! But they'll be awesome anyway, of course! :D
