Maia/ Xoti Fate?

I guess this could technically be under companion spoilers but it’s about the endgame cutscenes. If I romance either Maia or Xoti would they go with the Watcher at the end of the game, I remember playing first time and finishing the game that Mara ended up going back to the Navy even though I romanced her. Then the same thing for Xoti, does she stay with the Watcher at the end? I know it’s not really important but I like those little details the game has.

Also how do I romance Xoti? Each time I try to start a relationship with her it doesn’t seem to work…
