The Gormogon?
I know the writers probably planted Sweets in the show in order to be the red herring of all red herrings, but does anyone else think he may be The Gormogon?
He is a genius. He has gigantic teeth which look like veneers or fakes (The Gormogon pulled his teeth out). And he has the slight build we saw in The Gormogon being chased by Booth.
So, yes, he could be a red herring, or the writers might think that the audience would be smart enough to pick up on that, so he's actually The Gormogon while we all dismiss him because he's almost TOO obvious a choice.
