What do we think about. A jonelias sharing pain au. "I know i'm putting you through the horrors for my own selfish goals but let me take some of your pain. No, I don't have a reason to do this. Let me help you"
i think yes. i’m a big fan of mind link (or physical in this case) jonelias scenarios.
i think in this one sharing the pain might be a way for jonah to feel more like a part of the ritual. yes, he orchestrated it, but jon got a more active role. elias shares his pain to mark both of them with it, to tie them together. they will suffer together and they will get their reward together too.
you can go further and make their connection more straightforward. for every scar jon earns, elias gets a matching one. i would say on his original body, but by this point there’s probably not a lot of… skin left.
