Unless she's working to onboard new species that have just reached the point where they can join the Planetary Union, I'm done with that character. One too many back and forth subplots. She never seemed to learn her lesson (as understandable as that was for someone in her position).
If she does return, it would be good to see her be like a Dr. Taylor from The Voyage Home, someone out of place in time (as it were) but putting her skills to use in the Union none-the-less.
