0.25 adds about 7000 words of Badon with Charles, the priest at the church!
I don't know exactly when, but Olivia (the girl from Ashley's Badon date) is getting art and content, and Celica/Sarah are getting some as well. Ina will return after Deepwoods finale, which is almost certainly this upcoming update, 0.26.
Sam and Celica are.... trying to get along well enough to function, which isn't saying much, but they're trying! In general, everyone is getting pushed out of their comfort zones, so you may see some weird combos.
