Question: fire emblem three houses is it possible to recruit after timeskip?
Answer: Specifically, each House is able to recruit one student post-timeskip. If you recruited them before the timeskip, you'll have to get them again. They are: Lysithea for the Black Eagles, Lorenz for the Blue Lions, and Ashe for the Golden Deer. Some of your options at the monastery will change post-timeskip, too.
