Finn is incredibly competent and after his recovery, is in on all the major strategy sessions for the Resistance, giving A+ intel and helping to come up with plans of attack that are VERY successful. He's rising up through the ranks quickly and everyone is noticing how awesome he is. And Poe finds it SO, SO HOT. And trying REALLY HARD not to jump Finn's bones right in the middle of the room.

(+1000 if Finn has totally noticed how hot and bothered Poe gets when he's doing Command-type things and is using it to his strategic advantage in his campaign to seduce the best pilot in the Resistance.)
