From Create Your Own Story
"Now, now, Severus, quite unnecessary, if I do say so myself," Dumbledore says. He points his wand at you and utters the words to a countercurse. Suddenly, your legs and arms unfreeze and you become free of the Body-Binding curse.
"My apologies, Professor, I thought young Potter was one of the rogue ghouls we've been having trouble with...simply a precaution..." Snape stammers.
"Relax, nothing is wrong. Harry, I hope you understand."
Silently, you nod, whilst glaring at Snape.
"However, this is a meeting for teachers only at the moment. It would be wise of you to return to your dormitory," Dumbledore adds.
