After seeing Onion Friend I’m convinced that Onion is meant to be autistic. 

The way he acts reminds a lot of an autistic child. He speaks only to his family and has his own odd way of doing things that works for him. Steven is uncomfortable around him but his family obviously loves and accepts him the way he is. I think Onion broke into Steven’s house and stole his chips because he wanted Steven to play with him. 

Onion tries to do things he likes to do with Steven, and when he didn’t respond well to the snake or the birthing video, Onion decides to show him his secret stash of GUYS and GALS. That must be Onion’s special interest, something precious to him that he knows he and Steven have in common. That moment when he gives him one of his toys proves to me that he wants Steven’s friendship for real, he just has an unconventional way of expressing that.

So uh… Can we please not compare Onion to the spawn of Satan anymore? It’s really uncomfortable for me as an autistic woman.
