Au where Jon is somehow gifted natural ‘immortality’ (not real, but his body has ceased to age and he won’t die unless killed) and also him and Jonah are married.
So when Jonah (who was not given such gifts) needs to body hop again he shows Jon the candidates to get their eyes scooped and replaced and he’s like ‘which one is the hottest, be honest. which one would you be ok being married to’ and Jon tries to as blunt as his husband wants him to be. But the truth is that all of them would be handsome if gifted with Jonah’s eyes, for they’re Jon’s favorite thing about any body he’s ever had.
And Jonah has absolutely no idea how to react with knowing the love of his life loves the only remaining part of his true body more than the body of any other man so he just rolls the eyes Jon loves so much and says ‘very helpful, Jon.’
