quote:Before Comic-Con, Matalas had revealed that the villain for season 3 will be played by someone “familiar” but someone new to Star Trek, a new role played by a well-known actor. After it was revealed the villain was female during the Comic-Con panel, there was a lot of speculation about how it could be the return of a familiar Star Trek villain like Denise Crosby’s Sela. Matalas again clarified it is a new character, but said that there is a nod to Crosby’s Tasha Yar in season 3.
Also, "Not a huge star" but just someone well-known. And maybe someone who was in the 12 Monkeys TV show (just like James Callis was in s2, someone else who was in 12M has been cast in s3). Very few of whom strike me as well-known. Unless it's Hannah Waddingham. Oooh. I'm leaving that in in case it turns out to be correct...
