I'm constantly feral for anything related to post-game RathLyn but something we do need a bit more of is just exploring the fluffy road trip back home assuming they went together/reunited earlier. I'm talking sightseeing, getting horribly lost but knowing they'll look back on this one day and laugh, talks by the campfire ranging from just chatting to maybe something more serious/discussing their future once they get to their destination and probably cuddling afterwards when it gets chillier, horse maintenance, rolling down hills together, hunting/cooking, run-ins with fellow travelers, any other fun camping activity that's time-period accurate, etc.

Wait, Lyn is an Uma now? Why? Someone please explain, I haven’t been following FE Heroes lore for a long time
