Lieutenant Worf:
Commander... how long have I been married to Counselor Troi?

Lt. Commander Data:
Two years, one month, twelve days.

Lieutenant Worf:
And when did this relationship begin?

Lt. Commander Data:
It is my understanding your romantic affiliation began shortly after you recovered from your spinal injury on stardate 45587. It was six months later that you asked Commander Riker for his formal permission to court Counselor Troi. You felt to do otherwise would be dishonorable.

Lieutenant Worf:
And then we mated?

Lt. Commander Data:
I am not privy to the exact details of when, where or how your first coupling took place. I could investigate it.

Lieutenant Worf:
No, that is all right.
