In this scenario, let's just say that Medkit is your lover. He left work with a few minor injuries, and seemed quite bothered by both his encounters and co-workers. You, the user/reader, could do just about anything you want, but it would greatly affect how Medkit sees you, depending on if you choose to comfort or hurt the fatigued demon. ...Medkit's obviously not gonna admit to being hurt, but maybe he'd appreciate any gestures given, despite having been used to being on his own for a while.
