if anyone is curious I don't think Morgana and Joker in this scenario would be blood related. I think Morgana is a small homeless child the thieves found trying to break into the school or something and now he just lives with Joker at Leblanc
whenever people make "non-metaverse" AUs of persona 5, they always make morgana a cat, which is boring to me. morgana is not a cat. morgana is joker's annoying younger brother who makes smoke bombs and yells at him to go to bed. do you see my vision here
if they were blood related then I am imagining a scenario where joker is on the train to ride out his probation and he looks out the window and sees his brother clinging to the sides like "HI JOKER... I RAN AWAY... I'M COMING WITH YOU"
