You know what Bahorel Definitely took Eponine to prom at some point
He found out she’d never gone so took her out to get the Perfect dress, did her hair and makeup himself, literally cried while taking pictures as if she were his daughter and then had Combeferre sneak them into the gymnasium of the school he was student teaching at (knowing full well his entire career could be destroyed because he wanted Ep to have a nice experience) they somehow didn’t get caught? Even though they’re both in their mid twenties and very obviously could not dance like teenagers without losing their breath despite being decently fit people and ending up getting into a political debate with one of the teachers wherein both of them discussed real life experiences they’ve had and Bahorel even brought up law school. They had fun, importantly Eponine had fun acting as a kid at a school dance without having to worry about what she’s going home to. Combeferre is convinced he should not be student teaching at that school but him and Bahorel have never felt better because of being able to see Eponine happy.
Eponine said it was one of her happiest memories and will cherish the ridiculously cliche photbooth pictures forever
