>>92402600Now I'm just drawing from personal experience here, but I imagine that after a while, Gaz would get tired of isolation.
Yeah, sure it's all fine and dandy to just fuck off by yourself and immerse yourself in vidya and toons for while and not deal with other people, but after a while the lonliness gets grating. Talking to yourself loses its charm, and you find that older you get, the meaner and more bitter that little voice becomes, to the point where you start dreading having to hear it. And there's always that nagging feeling that you're missing out or have missed out, that you're not getting the whole package deal of life, and that if you don't start now, you never will. Or that you are the way you are not by choice, but becuase you can't make amongst normal people, that you're defective or inadequate. All while that little voice you used to talk to starts chewing you out, blaming you for being an incompetent fuck up. It would be maddening.
But again just speculation from what I know.
As for why Zim? Well Judging by her contempt for humanity and her Lack of shown friends, I imagine that she's just thought of as "That mean, moody Goth bitch" and left alone as no-one would want to deal with her. Zim at least, Respects and fears her, and is only somewhat deranged instead of a full blown idiot like her peers at the skool. She could probably bully and intimidate him into doing what she wanted.
