A Starfleet cadet who passed a loyalty test set by Christopher Pike and earned a place aboard the Enterprise.
Thira Sidhu was a Starfleet cadet at Starbase 28 when the station came under attack. She was ordered to guard a prisoner accused of mutiny, who turned out to be Captain Christopher Pike of the Enterprise.
Pike pressed her to release him, but she held firm and followed her orders. He then revealed the attack and the charges were part of a simulated test, which she had passed, and she was granted a posting aboard the Enterprise. She was played by Amrit Kaur.
