Today I'm thinking about Stan running into something extremely supernatural and fucked up during the 10 ish years he's spent on his own. Think Magnus Archives kind of horror where whatever happened marked him and he's no longer quite human. [This works with werewolves, vampires and other classic supernatural elements as long as Stan's fucked up, I'm not picky.] For this post let's say he was touched by the Stranger.
He has so many identities, he burns through them like a pack of cheap cigarettes and it feels good, to never be recognized. It feels safe too, to inspire fear instear of being terrified himself.
But then Ford finds him because if anyone can find Stan, it would be his twin. And he asks him for help. Stan shows up, of course he does. Monster or not, Ford's his weak spot and the only thing he ever wanted was to reunite with him.
When Ford opens the door however, he can't recognize Stan for a second and almost shoots him on sight. But then Stan speaks and Ford would recognize that fucked up voice anywhere so he lowers his crossbow.
He does the full paranoia checkup thing on Stan and he can't settle down because this is Stan, it has to be, but it's also not quite correct and he can't figure out if this is because he's forgotten details of his twin or if it's because this is an imposter. Could Bill even recreate a copy of Stan?
Stan tells him not to worry about it and eventually Ford does, because he has bigger things to worry about so he goes through the whole portal explanation and he guides Stan downstairs to see it.
The moment Stan sees the portal though, that monster part of him awakens and he knows he needs to bail or something terrible will happen. He can feel himself loosing control, the pull of the portal bringing the horrors forward.
Ford is too busy talking to notice. Stan tries to tell him but once Ford has started talking, it's almost impossible to stop him, Stan knows. He's unraveling at the seams though and he tries to step back but his body isn't his own anymore. He feels like a stranger in his own skin, a side effect of his condition he's gotten used to and can usually contain but not now. He thinks he may have started screaming because everything hurts so much, he feels split in half and isn't sure how much of it is literal.
He thinks this is the end, that he will die here. Or maybe this will somehow fix him, if it doesn't kill him. He feels something pulling him back, helping him get out even as part of himself lurches forward to get closer. He's not entirely sure what happens after that but when his thoughts clear, he's in a cage in a room he doesn't recognize and Ford is sitting on a chair opposite him, looking at him in fear.
