Yep, those are perfectly sane individuals alright. Definitely not completely batshit. Absolutely normal.

So, aaanyway, does that thing think it can rip a femur out of human body with its bare hands, or does it imply it has a knife AND a pipe, but instead of giving the friend one of those weapons it'll use the knife to get the femur, which would make for an inferior weapon due to being wet with blood which can't be good for the grip?
