They find Finn's world and Finn's family. Turns out Finn has 4 older siblings and they are all (almost) as attractive as Finn is. They're also a lot more confident and aware of their looks with healthy egos and lots of charm. So Finn is ecstatic to meet them, but also kind of wary because they are hitting on Poe hard and Finn, Finn isn't sure if he can compete.

But if Finn is good at anything it's defeating the odds, so he responds to his very attractive siblings' intentions towards the pilot he's been trying to woo by swallowing his fears and stepping up his game. He won't lose Poe without a fight!
