First, Chris would sink even further into depression. If Barb dies in her sleep, he's going to be the one who finds the body and it would probably screw him up further. However, without Barb to worry about, Chris's mood might improve slightly one he realizes his movement isn't as restricted as it used to be, and part of his current depression seems to be the result of Barb's reaction to Bob's death. I think we'll have to wait and see what happens in the end, though.Jokes aside, what do you think would REALLY happen once Barb dies? Surely he would call 911 and probably bury her in the cheapest coffin possible with no funeral, but then what? Here is why I think Chris could not manage without Barb.
1. He would not be able to afford all the bills with his tugboat. Chris gets around $1300/ month, and Barb gets a little less, but combined they get a total of around $2,500. This is enough to pay the homes bills. But with Barb gone, her SSI goes away unless Chris cuts her up and stuffs her in the freezer to keep collecting her checks.
2. Chris would probably not know how to fix things such as leaky pipes if they break. 14 blc would be infested with mold of a pipe leaked.
3. With Barb gone, anyone could walk into 14 BLC as they please. Chris hates jerkops, and probably would not call them if someone broke in. He would cry and yell and curse Ye ha me ha, but that is pretty much it. He could get raped, kidnapped, or even worse.
4. If Barb dies before she pays all of her debts ( very likely ), the debts could be passed on to Chris should he choose to stay in 14 blc after her passing. On top of bills and nessesities, he would not be able to afford it.
5. If Chris went back to jail, Barb would not be there to bail him out.
Financially, Chris isnt dumb enough to neglect the electric bill in favor of vidya. He can make fixed, regular payments just fine, his problem is that any money that he doesn't set aside for bills and food is immediately transmuted into Lego and vidya. As a result, he keeps getting bitten in the ass by sudden, unexpected payments that he can't make because he doesn't know how to save up.
Also, Chris would hide and call the cops if someone broke in to 14BC.
