I want Ember here to be Al's Arcane Protector friend who helps her with girly things, is bad ass with her, and just generally awesome chicas together. WHAT SAY YOU?
Gwen would appreciate her attitude and the way she gets shit done without flitzing about. She might even go out on a tentative limb as a friend, though not the super close kind. But she'd have her back whenever they were nearby or whatever.
Kier wouldn't have a problem with her. He's easygoing and is only really suspicious/wary of the other families so he wouldn't have a reason not to like her. Might not interact a lot, but I love randomness.
