For this connection , Eric’s ex should have originally been apart of the Prophets but what group they are a part of now is completely UTP . I imagine that the two didn’t have too serious of a relationship but they enjoyed each other’s company and eventually had a son ( Boomi who in game is about 4 or 5 years old ) . The relationship between them seemed to go down hill quick after that and she eventually left . The reason for this can be UTP . Maybe she didn’t think trying to raise a family with the Prophets was the right choice , or maybe she didn’t like being in the group any more, or maybe the uncertainty of trying to raise a family with the way the world is got to her . Those are just some ideas but it’s really up to you !
