Hey! Welcome back! Sirius fondly remembers you (though I don't remember why... but he's very happy to have you back and insisted I say so).

For Brandon, I have a sixth year Ravenclaw, Audrey Clavell. She's kind of antsy and agitated, for various reasons, sometimes just plainly vicious and unpleasant. She would match his moodiness right on. I could see them getting along if they didn't have annoying teenage hormones adding to the moodiness, but mostly I can see them fighting and hating each other, maybe? So if he needs a person to hold a grudge against, Audrey's available.

Then there's Madrigal Thompson, who seems shy until she becomes comfortable, after which she's just blunt and less comfortable with human beinds (probably even less comfortable with human male beings) than she is with magical creatures and such. But she's a loyal friend and generally calm enough to weather the storm of someone else's moods. It's up to you what you want to do with her, if you want to do anything at all xD

Let me know!
