Honestly, I don't have much brain juice with him specifically. Maybe I just can't think of anything currently. Maybe I just love him exactly how he is? Or maybe it's because I'm not as insane as I was about the series first time.
All I know is that I do in fact think he's autistic, (My two fav shotas have autism woww) and if you count any of the Savino seasons canon, he may as well have some Irish blood in em. His favorite color is definitely not orange like they retconned though it's blue lol
