After Kirk and company return from inside Regula I and are booking it to the Mutara Nebula. Khan fires a torpedo from the Reliant to "warn" them. The torpedo explodes and a short clip of McCoy and the Doctors Marcus in sick-bay is seen. McCoy is seen shaking from the impact and David Marcus is shown almost falling. Cut to the bridge, we see the bridge crew shaking from the shot and Kirk commenting about Khan "not wanting them to go in there." Before he finishes talking, a shapely young crewman is seen walking behind him. Then, David Marcus steps onto the bridge from the turbo-lift, while the same young woman is walking around the bridge. He sure got up there from sick-bay mighty fast!!
