(Im not puttin a characters thing, bc it's just ed and roy right? if NOT you can add the character thing and everyoe can have different issues idc)
^from what I Know and Want To Do, maybe roy is recently blind? and Struggling with the adaptation and doesn't have any friends or family near so maybe its a VA thing, so the person that looks out for him is like well we have this thing where we pair different veteran's up that have different issues and they help each other out to reach their equilibrium again, is that something you might be interested in giving a shot? We have housing here for it and everything^
