I wanna talk about my headcanons for PeterJonElias because it's fun, and I have been posting a lot for the tag, so I am allowed. This can be read as projection, or it can be read as just headcanons.
Jon: short, thin, British-Indian, and either non-binary or somewhere around there, with long greying brown hair. They/he/it Jon who is confident in their inhumanity. I also believe in monster Jon. He gave up on preserving his humanity, and it was gifted a giant spinx-type form that is fluffy and has black and green coloring. Brown eyes that kinda go green in the light. They are huge on physical touch and just generally spending time with their partners. It doesn't have to talk to them. He just wants to know they are there. I also headcanon autistic Jon because I am autistic, and I say so. Jon can go between the full Archive Monster form and the human form. However, they prefer one or the other. Jon, of course, is 29-30. Old Lady Hobbies.
Elias/Jonah: I am partial to Jonah being a long-haired trans redhead. She was a pretty little bastard who had men wrapped around his finger, and she knew it. Elias, however, has slightly more muscle, taller but not much, brown hair, and some graying in it. He's a rich twunk. Also, he/she Jonah, I've seen someone making content for transfem Jonah lately, and I love it. Jonah is some flavour of trans, and idc which. Elias has tanned skin, and Jonah was pale as hell. She is a cuddle person. He is a little possessive but would 100% give up on a relationship out of pure curiosity. She likes watching her partners and just knowing the things they enjoy and the little details that make them who they are. Jonah just has his many eyes, and he's happy with that. Elias is 48, Jonah is 245.
Peter: Blue eyes, pale skin, longer white hair. He is around 45 but looks closer to the late 30s range. He's fat, and he's taller, and he takes advantage of it. There's a document one of his husbands wants? Too bad, it's on the fridge now. He just likes having something to miss because he feels like it makes him closer to his God. He didn't pick his partners. He was half roped into dating James, and then James became Elias, and Elias brought in Jon. He doesn't know how this happened, but he's fine with it. He will also occasionally, and without warning, give them random gifts. It will just be there, no context, and no explanation. I also like Peter being autistic.
Peter kinda just drags the other two into his lap for quiet cuddles. Jon plays a stupid game on his phone, might occasionally get him to look at something, or just leaves him 'alone' completely. They both have artsy projects they enjoy as well. Jon can quietly sit crocheting something while Peter sits and makes a Ship In A Bottle or something. They can just sit and enjoy each other's company while staying silent. Elias will hang out with them but needs to either lay on someone or be active in a conversation with someone. No one is allowed to forget that she is there. He always wants one person's eye on him. Elias might put on an inaccurate documentary just so that she can yell at the TV about it and to make sure they know he is there. Elias likes being seen.
This is all for now, but I love the three of them, and they deserve to be awful and love each other over it.
Let me know if anything is written weird or doesn't make sense, and I will try to clarify it. :)
