I'm still relatively new to the show. I've been slowly catching up thanks to my father recording episodes, and finding episodes online. Zack had been my favorite character. I'd heard a snippet about Zack and the Gormogon. I wanted so badly to refuse to believe. Not wanting to wait to watch the episodes in order (I was still in season 2) I skipped ahead. I can't believe I liked that psychopath. He threw away his job, his friends, betrayed them, all to help that evil bastard. I know that he returns for a couple of episodes (my father told me). Hopefully that piece of crap never returns to the show. At least I know the truth now. He is evil, I will have never, nor will I like an evil character (liking an evil person before their true nature is revealed doesn't count).
