Maeve and Hagan are siblings, so it makes sense they'll stick together, especially Maeve making sure that Hagan doesn't run off on his own again. They're still arrivals from the countryside and not born in Trunau, so Maeve would cultivate some friendships with natives like Halcyon to build some useful connections in town. Rhidia's a trickier one, I like Gunmetal's idea of having had an previous adventure with her.
