Dear Professor McGonagall,
I refuse to allow my future mate anywhere near that mad man you call Headmaster, or that death-trap he calls a school.
He has interfered to much in Harry's life already. If i hadn't saved him the Dursleys and freed his godfather from his unlawful imprisonment, he would be a shell of the happy child he is now. If Voldermort doesn't end up murdering Harry, then your carelessness, neglect, and plans for the 'greater good' certainly will.
I will join Harry in the wizarding world when the time comes to fulfill the prophecy. And only then. Until that time, I demand that you follow these three rules.
Keep to yourselves. Leave us alone. Do not interfere.
My brothers are watching you... Closely... So i know if you disobey.
Salutations,
~ Castiel, Angel of the lord.
