Re: Also wanted
Her liking Fred too could be fun! The twins are popular guys, I would expect there were some crushes. I would assume that Anj doesn't know/used to know but assumed she'd gotten over it, because although he's the one who asks her to the Yule Ball, she doesn't really hesitate in accepting. And she's not the sort to be awkward about turning a friend down.
Puff player is fun! That means she'd know Danny well too.
I don't think Anj would be totally put off by the animals thing, Lee had a pet tarantula. She wouldn't be into it herself but she wouldn't super mind.
I'd been going to ask, or offer really: I'd like a cousin for Rolf, but I want someone who has at least one older sibling. Any interest? Would that fit? Her being into creatures could tie into her being part Scamander.
