You are a navigator on the USS Enterprise, you regularly work along the helmsman and your partner, Sulu, today is one of those days. You both feel tired, you both have been working since 1100 and it is currently 2100, almost 10 whole hours of nonstop observing and navigating, with another hour to go before you can both descend to your respective quarters.

You look behind your shoulder, noticing Captain Kirk isn't currently seated in his command seat. An idea surfaces in your mind and you are quick to act, you turn around and place a gentle hand onto Sulu's, you glance at him, he glances back.
