… and So Is Number 1
The other big departure during season one’s finale was not by choice, however. It was revealed earlier in the season that Commander Una Chin-Riley, aka Number One (Rebecca Romijn) is actually secretly an Illyrian, a species of near-human genetic augments that re-engineered their bodies to suit the worlds they colonized. In the wake of the Eugenics Wars, the Federation and Starfleet banned augments entirely, including the Illyrians, who were forbidden from Federation membership or joining Starfleet. Oopsie, Una!
While Captain Pike kept her secret and stopped Number One from resigning her commission when he learned, eventually things came to a head when Starfleet discovered it too, arresting Una at the climax of season one.
