I've always been curious about the extent of services Chris's disability entitles him to. With the way things are looking now, I think Chris's only real chance for surviving on his own depends on help from someone who can professionally assist the mentally disabled, especially with their finances. I imagine Barb's passing could possibly result in an outsider, be it a social worker or someone from Rocky's church, checking up on him only to discover how severe things are. As morbid as it sounds, that might be the one thing that would truly turn things around for Chris. Of course, Chris might be so stubborn that he'd turn away any help he could get.
Either way, as flawed as Chris is, he doesn't deserve to live in 14BC. Hopefully the house is truly beyond repair and he'll be forced to Zap To The Extreme elsewhere.
