Leanne may be a little quiet for Kee's tastes, but she'll definitely know her and be all for the pro-Cedric thing. Plus classes!
Audrey sounds like she'd get along well with Kee, though they may not know each other all that well (yet?). Well, except for that Kee's got just a little conspiracy streak running through her and she doesn't trust the Ministry all that much, and future Ministry-ites are in that same boat. Sorry!
She probably won't be too acquainted with Alexandra yet but there is plenty of time!
