Sheehan's in a weird headspace, too. Arthur dropped the "I love you" bomb on him AND he had a huge breakthrough/fight with his inmate, so it can go any place!
Perfect timing! And Sheehan has never done a violence in his life (I mean...aside from WW2) and considered banging really hard on his inmate's door as being a little overly aggressive
Random shit, mostly passive unless someone comes to change things up for him, around the Barge. He's doing research into modern times (guns) and relaxing and thinking about stupid recent shit that's on his mind.
come do violence with him. that will earn brownie points
