Adding onto the sharing thoughts soulmate au just imagine if OG Elias is still in there. (Which I honestly believe because it’s very beholding to make Jonahs victims watch.) And he’s annoying Jonah and and Jon has to deal with that on top of all the noise from the institute
I totally agree with you about Elias still being in there it makes total sense.
But can you imagine how much Elias being in there and Jon being able to hear him would wreck Jonah’s plans? Elias has probably been watching for years, maybe decades, and suddenly has a phone line directly to someone besides Jonah for the first time ever? Jon is going be told all sorts of things Jonah really doesn’t want his soulmate to know.
(Its even worse for Jonah if Elias notices Jon first, which is likely because he has less to distract him. Elias doing the mental equivalent of sneaking around to make sure Jon has the absolute most possible information.)
