Finn and Poe are captured by the First Order and Kylo decides to interrogate/torture them. While "searching" through Poe's mind, he finds out that Poe is in love with Finn but has been keeping it a secret from Finn. In order to torment Finn, he tells this to Finn and about how Poe feels heartbroken/depressed cause he feels like Finn will never love him cause he's in love with Rey.
+100 if Kylo reveals that Poe has either attempted or considered suicide cause he couldn't deal with the heartbreak
+1000 if he tries to see if he can make Poe die of a broken heart by seperating him from Finn and bombarding him with depressing feelings till he loses the will to live.
