My mistake about the mention of a Romulan vessel...I think I mixed that up when it was being discussed on the bridge. The dialogue still dosn't give any indication that she reported the battle to a superior officer and then was dismissed. We don't even know where she immediately came from when she was changing her outfit. All I'm saying is that i would have liked to have seen an added line that she reported this...I'll have to go and watch the scene again
Gaila says that Uhura's back early, obviously from her job at communications where she monitored the transmission. Having her say, "I told my superior officer" is unnecessary since it's implied by the fact that she was sent home early.
