My Solo Boys
So Anakin was there and he stood up with his parents to witness or whatever. He was wearing Jedi robes, basically, and he would have been grinning the whole time. Afterwards everyone got a hug, his parents, Rey, & well, maybe not Ren. He kept an eye on the bonfire all night, but danced with Nico and probably most of his friends if they had the opportunity to dance.
On the other side of canon, we have Kylo who was there as his mom had asked him to be. He didn't smile a whole lot and probably looked as if he was ready to dart off at any moment. He was, notably, not in his regular costume for the first time since he arrived here. Eliot helped him pick out and get fitted a three piece dark suit, so he was wearing that, with a maroon shirt, and Eliot knows clothes so he probably looked pretty fine (example image, but obviously with maroon shirt and jacket) if hella awkward while looking it. He didn't really talk to anyone who didn't talk to him, but he also didn't create a scene probably, so that's growth, right?
