Years into her Jedi training, Rey is an integral part of the resistance while she and Finn (or she, Finn and Poe) raise their surprise kid (Poe gave them the safe sex talk just a leeetle too late).
Luke has never approved of her relationship with Finn, fearing it will make Rey vulnerable to the dark side. She never agreed - until she's ambushed by the First Order while travelling with her family, and Kylo Ren snatches her kid and hyperdrives out of there.
Ren *wants* Rey to go mad with rage and chase him to the end of the universe, so that she succumbs to the dark side and joins him.
But Finn manages to keep her level and true.
(Could be Poe and Finn instead of just Finn of course, ot3 all the way)
Finn/Rey, or Finn/Rey/Poe, child kidnapping, Finn pulls Rey back from the dark side
