I had that thought. But I rather think its the teacher with the glasses whose name I keep missing. the chemistry teacher. he was the one who tought the class of the victims, and he is back. However, I do think that Gerard is supernatural by how he reacted to that black sand barrier at the club.

I think there trying to make Gerard seem like the master, but I don't think it's Harris or him... Gerard definitely has something fishy going on with him though... and what is it with teen wolf and taking on actors from other shows! It's so cool! The guidance counsellor is from PLL, Chris Argent is from the secret circle and Lydia's mama is from TVD!

It is Matt for sure. He is afraid of water, and he acted odd when he saw the tablet talking about the Kanima.

I believe Gerard has something to do with the Kanima but I don't think he's the master. Matt could be but now that Gerard drowned him idk if he's coming back...but I hope so. :)
