I see your Poe Dameron admiring the hell out of Cassian Andor headcanons and love them, but raise you this: Poe telling Finn stories during his recovery about Bodhi Rook, a “nobody” Imperial cargo pilot who risked his life and left his probably relatively safe life to deliver a message that would change the tide of the rebellion and war against the Empire, a man who could have kept living his life none the wiser, but opened his eyes to the horror of the Empire and, even though he didn’t think he was brave enough, had a heart so big that he walked out on his own to brave the unknown and shape history. And Finn, who has struggled with his own fear and sense of self, realizes that he isn’t alone - that there was someone like him in the old Rebellion - and there is hope.
