Suprise, surprise...

I just got a phone call from my grandmother. She is flying into New York for Christmas as a surprise on 23 December and staying in a hotel there till Saturday or Sunday. I love my grandmother and I am so happy I will be able to see her.

But I think she will probably want to visit the school after Christmas. How in the world can I explain the demon damage?!?!?! I cannot say all are mishaps with powers!
