Optimistic Prediction: Barb finally croaks, Chris then sells the hoard to pay off the debts the Chandlers owe, if not also the house. He's then moved into one of those subsidized apartment complexes for people with low income/disabilities by the state's Health & Human Services department, and proceeds to shit the place up with his Lego hoard.
Realistic Prediction: The old bitch still remains alive for some inexplicable reason, Chris shits his pants and does nothing, save for making asinine anti-Trump videos and plays with Lego. Also at least one run-in with the law, probably after trying to evade one of his many store bans.
