Now that I think about it, I'm sure him and Barb have had "the talk" at this point. Ya know, the one where she says "Chris, I'm going to die soon" and then tries to walk him through all the shit he needs to do to not end up living on the street. Then again from what I know of Barb maybe she wasn't/isn't thinking that far ahead and Chris is going to be totally lost when she goes. If they haven't done so they really need to sit down together and work that shit out. Chris is gonna have to be a big boy (girl, whatever) from now on.
I'm honestly worried for him. Chris can be a right ol' piece of shit but I really don't want to see him end up worse than he already is. And for the life of me currently I can't see any scenario where he gets his shit together and avoids a group home or a gutter. I doubt Cole is going to come running to his rescue, it's pretty obvious he wants nothing to do with Chris's ongoing internet meltdown or his mother. I could imagine him going to the funeral if only for some sense of closure (possibly, who knows), but after that Chris will be lucky if he ever sees him again. If he's expecting Cole to help take care of him he's going to be horribly dissapointed.
He's gonna have to start saying the J word. The tugboat is meant to supplement income he gets from a low skill/part time position. Hell, I could see him doing some sort of overnight stock position at wallmart or something. chris could maybe scratch by a more or less comfortable life for himself if he's careful. And if he got something like that he wouldn't even have to interact with customers, just put shit on shelves and empty trash bins. That's a pretty easy 6-8 hours of work right there.
Alas, Chris will not do that. So it's either he sells the house, sells the shit IN the house, then buys a small apartment somewhere and lives off the tugboat to the best of his ability, or he's homeless. And chris will not survive being homeless.
