Emony (the gymnast) appears prominently in the Discovery novel ‘Die Standing’ that tells MU Georgiou’s journey between seasons one and two.
In the book, Emony had a covert identity as an operative for Starfleet Intelligence and was paired with Georgiou for a mission.
So, I have been hoping that Emony might appear in the S31 event movie.
While Chase Masterson’s Leeta took on Emony’s identity in the Trill zhian’tara ritual, there’s no reason to think she couldn’t be very different looking than Chase. So I am hoping Emony might be one of the yet-to-be-named female main characters.
