[ as much as keith tends to make a habit of minding his own business, there's not a whole lot of stealth that a wheelchair can provide. which is to say, he watches as tony wheels himself from the door to the vending machine looking like a sickly man on a mission. he doesn't mean to stare exactly, but he can't help how his eyebrow starts going all the way up into his hairline either. ]

Uh... not that I can't understand wanting to get the hell out of medical, but are you sure you don't need to be wheeled back instead?

[ if he's really dying that is, anyway. what keith isn't saying here is that for a dying man, the dude sure is talkative. ]
