Re: Attendance
Eliot would have returned the hug, gotten a hug smile from the hum, and probably patted Q's shoulder while beaming.
Remus will thank Q for the birthday gift since I don't believe he actually has.
Alice will smile but is largely keeping quiet.
ELIOT HUGS PETUNIA SO HARD. Like it lingers and there's a falter of how much he actually is trying to keep up the persona, and since Petunia knows him, she might be able to see the little splinter that shows just from hugging her because HE'S NEEDED YOU. But he doesn't want to come to you. But he hugs her very hard and let's her fuss over him and probably kisses her cheek because he loves her a lot.
Remus, meanwhile, is engaging with Petunia's friends friends and he loves you, too.
