Pent and Louise (and any of their family, if you like), holidays - because I think your family fic is cute, and even if you don't know Klein and Clarine from FE6, there's still Erk :3

Lucius and, idk, anybody you like, sharing a meal

Harken and Elbert, knightly duties

Renning, either pre-Bertram, or post, sparring with Geoffrey :DDD
