but it is confirmed that the exiles are the midnight crew, snowman and also kind of supposed to be team sleuth, mk and the three female counterparts. which means she can't be an exile

Exiles are all the Prospitians and Dersites that leave the Session to go live on the destroyed planet. They may not find the capsules to contact with the Session, but is it so weird to imagine they made a little Prospitian Colony separate from Midnight City? Maybe like. High Noon Village.
