Hey all, this is Ashley with Eddie baby, and we are not going to talk about how long he took me, all right? All right.
Edmund's kind of a shite Slytherin in day-to-day life because he does not make cunning plans or wax poetic or bitch about other people. In fact he is a fun, amiable fellow who tries to be considerate, honest, and understanding. The only reason he is in Slytherin at all is because he is very ambitiously determined to be the best head healer to ever heal heads, on account of his brother being in the loony bin. He is not in the slightest secretive or respectful of the fact that his brother's a bit crazy, so pretty much everyone can be aware of this. It is okay to joke about. Ed likes jokes.
Ed's best friend is Regulus, so his primary loyalties lie in that direction, and by extension to Reg's friends. I cannot say he is particularly fond of Sirius or his friends, on account of Sirius being a douche and all. But he came out of his lonely-little-boy shell around first or second year and would have tried to reach out a bit. He's also a member of an old Pureblood family and thus has made the high-society rounds. And eventually he will be a DE but he's not really gonna be motivated in that direction for another year or so, barring extreme circumstances. So! Friends, acquaintances, enemies, you know the drill. Profile is here if you want more details.
