The odds of him getting on Section 8 are probably pretty low, for sure, but if he does manage it then it probably represents his last, best hope of getting a bae, any bae, to at least talk to him. Section 8 can be difficult to lose if you manage to do the bare minimum, and he'll undoubtedly have a caseworker to keep him in line. The only real trouble would be if someone who wasn't on the lease (say, a crackhead or homeless chick who convinced him to let her in and make her a copy of the key) was caught being there, but even that's tough to prove and there's a bunch of bureaucracy they'd have to wade through to do it.
I can just picture Lucas, in his infinite(ly small) wisdom, thinking he'd hit the jackpot when some mid-30s drug addict or whatever showed the slightest bit of interest in him and convinced him that they were gonna score once he let her move in, only to show up with a bunch of dudes and force him to live in a closet or something
