Jon's the one who brings William. William didn't believe him when he told him about the evil guard-pig, so he tags along with him one day and just doesn't leave. Bill doesn't do anything, really. He just lounges around with Gabe - the Guy On The Other Side Of The Fence; that's actually how everyone describes him - and they write 'songs' about Gerard & Ray & Frank & Bob & Mikey that have a lot of obscene lyrics and references to goat fucking - which really is so tasteless, except you can't help but like Bill anyway and Gabe is Gabe. Occasionally they'll get high with Joe - the guy who delivers all the donated pet food from local businesses - and eat all of Bob's cheetos.
