La’an’s Out of Action…

The Enterprise was rocked by a series of organizational re-shuffles at the end of season one beyond Hemmer’s death. Its head of security, La’an Noonien Singh (yes, of those Noonien Singhs), after multiple harrowing encounters with the Gorn throughout the first season—dredging up trauma from her past, having been captured by them as a child—stepped down from duty to go on a leave of absence to help another young survivor of a Gorn attack, Oriana, find her home.
Pike forced La’an to promise she’d return to duty some day, and it seems like that moment’s going to be sooner in season two rather than later, considering freshly released images from the premiere see the crew reunited with La’an during a new mission.
