poor kieren, when it rains it pours etc…! i'm totally fine with a good serious injury of some kind; he's got a lot of layers, so his hands and neck are most vulnerable unless they get into some sort of scuffle or it happens indoors to have his arms fair game. maybe his shooting arm, force him to get a new hobby until he heals LMAO

even if he couldn't knock him out proper, he'd figure out how to restrain him and then hide him at his cabin; especially if other people are gonna be mad at kieren — he'd kind of look at it in terms of kieren had his back so he has a debt to repay.

additional canon things: i dont know if maccready is technically irradiated, but i'm sure he won't taste good regardless
