Parvati!
I've been keeping an eye on Harry since we all left the third floor an hour ago. You need to get out of class NOW. I think he's going to try it now, and I don't want to miss it. I want you to come along too. Fein sick or something, but come out and meet me in the east side courtyard. I'll only wait for the next twenty minutes and then you're on your own,
Hugs, Lavender-
