Here's something that's always puzzled me about The Wrath Of Khan... why is Sulu never left in charge of the Enterprise bridge when Kirk/Spock aren't around? He holds the rank of Commander and is clearly a very experienced officer, yet Lieutenant Saavik has the Conn and even an unnamed Navigator sits in the Captain's chair whilst Sulu is at the helm.
Does anyone know the reason why?
