Being as stubborn as Dave has been in the past, could you imagine him not paying bills/ignoring them in favour of playing video games to let his mind escape. Only for one day him to be live streaming and during that the IRS has to physically drag DSP outside his house all while he wails/screams it was all Tevin's fault.
I think he'll try to squeeze money out of his parents as much as possible before their death, his Dad seems like he's doing above average at least not sure about his Mom. If it's not a money issue I think sooner or later he will snap. No human being can isolate themselves all day playing video games for nearly most of their life and be mentally sane, I don't think he has bothered to make any friends in Seattle either. A great way for him is to go to game stores or card shops. Even a meetup, but we know he's too paranoid/scared or just plain too socially segregated at this point to do any of those things. When an individual is afraid of lots of people like a mall, he will avoid that mall, sooner he'll avoid a mini market because it reminds him of said mall, then he'll even avoid small convenient stores and eventually have everything delivered so there is as little interaction as possible. The problem is Dave has zero accountability, he is in a unique situation career wise. If he had to work a 9-5(even though their easy SNORT) he would at least have to wake up/show up at the same time and make small talk with people at work, but him being isolated at home he has to do neither. Hell with Amazon Prime, Uber Eats, he technically has to never leave the house again! What a sad, sad, sad man. I don't wish any harm towards him but I don't care if his life collapses in front of us(it is already) this is like the slowest train crash in existence but it's getting slower, and slower towards making impact.
