Why Gator won't leave the KillStream crowd:
1 - He has zero social life outside of the internet and doesn't have the charisma or capabilities to actually latch onto any other group online, which is why he only alternates spending his time between KS areas and anonymous image boards.
2 - He has accomplished literally nothing in life except being a hanger-on to a Zceleb, getting half of a tech degree and doing literally nothing with it, and living on his own with the money from bagging groceries. No serious relationship, no close family, no career outside some fantasy CompSci job that will never materialize because he's too simple and lazy, and all this will only get harder to change because he is already incredibly unhealthy and only getting older - no one is going to give him the 'dumb kid' excuse for acting like this in his 30's.
3 - He is the embodiment of the GamerGater stereotype, a loser who compensates for his failures by bitching about imagined persecutions at the hands of cartoonish online enemies that only exist in his head. He needs a cause to fight for, just not one that puts him in actual danger or that requires actual work and sacrifice. Something to keep him excited, and to give him a sense of accomplishment when he 'wins', all from the comfort of his computer.
Gator and Ralph will keep on being Internet trailer trash just like Julian and Ricky, with occasional visits to jail or the hospital, jumping from scam to scam until Ralph dies.
