howdy! I'm Joie, one of the other mods around here, and i have five characters!
Justine already mentioned, Mina (sagacious) went to college in Michigan so there is the potential for them to have a past connection. And if not, then there is also the potential for him to get involved with the LBJ's education department. Savannah (jurisdoctor) acted as shelter leader for the past year but now with the new government shift, she'll be the district representative and overseeing activiites in the lbj district. If Keagan is interested in getting involved in the new educational programs opening, that would be awesome!
Those two are the most obvious connections but we could definitely throw Keagan against Marina, Bea or Isaac and see what happens!
