BB-8 really wants its human to be happy and in love, and who better than Finn? Finn was all Poe would talk about when he came back from Jakku, and after Finn woke up from his coma, Poe hardly left his side when he wasn't on a mission. Now, the two are inseparable, sharing a jacket and a room.
Unfortunately, Finn seems resistant to all of BB-8's machinations, which include tripping Finn into Poe's arms, dumping a bucket of cold water over Finn's head so that Poe can warm him up somehow, leaving sappy romantic holovids in Finn's bunk to give him ideas, etc.
Turns out Poe and Finn are already together.
+They both catch on but don't say anything because BB-8's matchmaking attempts are amusing ++BB-8 starts leaving holoporn, which they put to good use +++Rey somehow finds out about this
Finn/Poe (+ Rey), BB-8, matchmaking gone wrong
