Once I was proven right ( Which involved a devil's trap ), I enlisted help. I exorcised the demon out of him. Not before losing some of the trust of the coven, which was fun to gain back - but, he was dangerous.

( And so began the saga of actually David and Ezra. There's more, that he trapped the demon right as his mother and father were put into harm's way, but Damian was of help, and all turned out well. Well, eventually. )
