So. We've already established his relationship with Roger, what with them being brothers and all. Higgs was a year above him in Slytherin and thinks Max is a tosser. Jun was a year below him in Slytherin and might also think he's a tosser but for different reasons. Oops. She's friends with Siobhan but I don't think that extends to Max. Unlike with Oliver, who is also friends with Siobhan and therefore thinks he's friends with Max, too. CONGA RATS.
Evan does not know him but wouldn't like him if he did, almost definitely. Aisling probably would like Max quite a lot, actually. She knows his type (a posh lawyer! Aisling's like 'yeah, that's like home'). I think she is also friends with Siobhan (so basically, Max's better half has a lot of friends in my characters, Max does not).
Hermione doesn't know him, nor gives a shit, sorry! Byron... idk. Probably remembers him from school ish? He also doesn't really care about Max.
