It explains his obesity as well. There's a saying that abs are made in the kitchen. While Jon's a long way from a six pack, the concept of overeating applies. He's a junky and once he finds something that makes him feel good he pushes it beyond the limit, be it large amounts of unhealthy food or massive daily doses of public ridicule. The common bond seems to be that all of his pursuits are self destructive.It's clear as a fucking bell he's addicted to the dopamine hit, as mentioned above. Wether that hit comes from levelling up in an MMO, shooting opiates into your bloodstream or getting fucking humilated by hundreds to thousands of people daily, he's a fucking raging gibbering addict. Give him treatment ASAP.
