You grab first aid kit in another room. You think he need to treat his wound. It looks deep and painful. You hurry over to him and place the kit on table.

"Here, change into this. After that we'll tend to your wound." He thanks you and grab the stuff.

He enters the bathroom again leaving you all alone in your living room. You start wondering where he got that injuries. You should ask him later. It will be bad if its infected.
