I'm cautiously optimistic for the presence of non-origin companions. Hopefully this will mean "companions without tadpoles" rather than "companions that have tadpoles, but just don't start on the MF ship." If so, it would make sense that the more egotistic/abrasive/evil characters are origin characters, as that gives them a reason to work with Tav & each other. Whereas the Good characters will want to help regardless of their personal plight.
