au where john doesn't go missing, dean never gets sam from stanford, and almost five years from when sam walked out on them and never looked back, dean gets a call from a sobbing woman telling him that sam's missing and she needs his help
dean and john go to palo alto where they meet jessica, an engagement ring and a thin gold band on her left hand, which is how they find out that there's one more person out there carrying the winchester name
they don't even get to linger over the fact that sam's married, that they're talking to his wife, because she tells him that he just disappeared, that she came home and he was missing but their living room was covered in sulpher
she tells him about the past two years, about how sam has been getting visions of other psychic children like him, some who had mothers that died in their nursery at six months, others that didn't. they met a lot of them, kept in regular contact, but the past few months they've been disappearing one by one and now sam's gone too
(jess keeps the telekinesis to herself, keeps the information about the demon to herself, doesn't breathe a word about the mind control or the super strength or electric shock or any of things that the other children could do that they'd been slowly testing to see if sam could do too. she's gone to dean and john because she has to but she doesn't forget that there's a reason sam hadn't gone to them when this all started happening, that instead he'd come clean to her about every lie about his life and told her to run, that something was coming for her and for him too
she hadn't run then and she won't now)
dean is losing his mind, all these things about his brother that he didn't know about and has to deal with, meanwhile john is quietly having a little mental breakdown, realizing this is the moment, where if he can't save his son then he's going to have to kill him
jess refuses to be left behind, reminds them pointedly that she's sam's wife and they're either doing this with her or not all
so dean and john have to deal with their sister in law / daughter in law tagging along and helping them track sam all while obviously not liking or trusting them an inch
