While Poe is off on a mission, an urgent and vital mission comes up where Finn needs to infiltrate a First Order outpost by pretending to be a Stormtrooper again. It needs to be Finn due to his internal knowledge of the First order and Stormtrooper protocals. He hates the whole idea, but knows how important it is and agrees to go.
When Poe gets back, he finds out that Finn was sent out on this mission. He also finds out that he was due back 2 days ago and hasn't been heard from at all.
Poe is pissed, and nothing will stop him mounting a rescue mission, by himself in a stolen X-wing if he has to.
Poe/Finn or Poe&Finn: Finn MIA.
