Robin was the hardest to pinpoint. He would have been very EASY to spoil just by making him a DnD character. I had to decide if I should actually do the body or the Demon. I decided that we would just go with the body and what the body would be considered. IDK if there's a way to be possessed by your patron in DnD, but if there is, that would probably be how he is, probably switching between Robin (the body) and the Fiend (Which would be the Robin, you guys know).

Make sure you look at all the intermissions before this starting from Intermission 50
