expelled Harry?

[kitsuneasika]

I'm rereading OotP, and have just gotten to the part where Harry and Sirius are discussing his upcoming trial, and Harry asks if he could stay with Sirius if he's expelled. This led me down several bunny trails and a bit of searching before I finally decided to take the plunge and post my request here.

Basically, I'm looking for a R/S (of course) fic where Harry was expelled from Hogwarts in OotP, and goes to live with Sirius in Grimmauld Place. Any length is fine. Thank you!
