2. Acting: Una confronts compromise
Rebecca Romijn gives one of her strongest Una performances in the series because the episode makes her professional promotion personally uncomfortable. Una begins the mission as the newly promoted commander leading the landing party, but she quickly has to lie to Klingons, manipulate Roman, work with a resistance cell, and accept that her actions may put innocent people at risk.
The key emotional turn comes when Una realizes that following every rule would mean allowing the Klingons to complete the shield project. She cannot save everyone or preserve Starfleet procedure at the same time. M’Benga becomes the person who pushes her to accept that moral clarity does not always come with a clean solution.
Romijn makes Una’s discomfort matter. She does not suddenly become comfortable with deception because the mission demands it. At the end, even after the EMP gives the planet a fighting chance, she still has to process what it meant to use Roman as part of the plan. That lingering unease is what gives the episode its emotional weight.
