I think future!Jon should have to deal with past!Jon age regressing. Oh my god. Oh my god. It’d be a fucking trainwreck.
They are being given the opportunity to show a version of their child self the kindness and affection they desperately craved but never had. They will likely never experience it themselves. This is the person they hate the most. This is them, the person who will make every stupid, awful decision they made in their own time. The incompetent prick who can’t even hold himself together enough to act like an adult at work. Having the gall to act small and scared and pathetic like he’s suffered a fraction if the pain he (they) cause others. Like he has the right. This is a person who doesn’t understand why they hate him except that he has never been enough, and the adults in his life have rarely liked him. He’s so vulnerable right now. Would be so easy to hurt and the Archivist can smell his simple, childish fear. Mr. Spider a fresh, raw wound they could so easily sink their teeth into. Genuinely holy fuck there’s soooo much potential here.
They could hold their past self in their lap. They could hold him and tell him that he’s a good boy and gently rock him while they read him something nice until he fell asleep and tuck him into the cot and not say anything when he wakes up mortified and ashamed.
Or maybe could take advantage of him. Probably they wouldn’t. But they could. Could put him on his knees and make him lick them open, unsure and confused and not understanding but eager to please. To be good. They’re so small and pathetic and naive and innocent and something about it is making future!Jon so. So angry. But they could tell him to kneel and to put his face in their folds and lick. And when he got wet, started squirming, reached a hand down to touch himself, they could slide their foot between his legs and make him hump it. Could call him a slut and he wouldn’t even understand, not right then, not really. And wouldn’t it just be so easy? To lash out? To sully this man? To ruin all the things that make them so uncomfortable and unsure? The softness, the childishness, the smallness?
And if they were feeling vindictive they could just… take out all their anger on him. They could lash out with cruelty. And he wouldn’t fight back, not like this. Wouldn’t argue. Wouldn’t know what vulnerabilities to strike, wouldn’t be able to being their shame and misery to the surface so easily. No clever words or sharp tongue now. And the sobbing would make future!Jon feel guilty, and the guilt would make them cold and distant. Have them leaving him to have his little fit all alone. To pick up the pieces until he could come back when he was feeling grown, when he would understand that future!Jon had neither the time nor the patience to deal with his bizarre, childish meltdowns.
Or maybe if they didn’t think they could be trusted with him like this. Couldn’t bring themselves to be kind or cruel they’d just. Ignore him. Snippy when he was bold enough to demand their attention but otherwise acting cold and distant and unbothered. Or maybe, perhaps, he’d feel uncomfortable enough to pass them off to someone else. Would be willing to risk leaving them to Elias’ tender mercies, if they felt it would be easier.
