Tim honestly can't imagine Jack ever taking a bus. It's just... wrong, a square peg in a round hole. Jack's all about the conspicuous consumption, having the fanciest things and the newest tech, so having to get around by public transit or on foot must be a blow to his ego.

And just about every fiber of Tim's being is telling him not to accept Jack's so generous offer of a guest bedroom-- not just because he doesn't want to live with Jack, even if only temporarily, but also because everything he knows about Jack is telling him that this is some kind of trap. He's not sure how, but Jack doesn't just like... do nice things out of the goodness of his heart. There's always an angle.

But he also doesn't have anywhere else to go, which sucks.

"Uh, yeah, okay?" He honestly probably wouldn't have even thought to look in the garage if Jack hadn't mentioned it. "I'll try not to be a bother for too long."

Basically, get his own damn place ASAP.
