On later viewing I noticed crewmen Burke and Samno, when the klingons just arrived on board Enterprise, complaining about klingon hygiene etc. Suddenly they bump into val'eris, which asks: "don't you men have work".
I'm not quite sure if I interpreted correctly, but I'm pretty sure she told them to get on with boarding the klingon ship.
Wow! I never put that together before. You've just improved this film for me, and I already loved it. Thanks!
Have you got to the realization about why Valeris shoots a phaser in the galley rather than just reminding Chekov about the alarm?
