Congratulations on your promotion, sir, I have no memory of it.

The last thing I remember was disembarking from the Enterprise after the war-criminal Nero was defeated. I went to sleep the following evening, around 2200 hours, and I awoke in the unfamiliar quarters.

As for the Captain, he does not even remember the escape from the gravitational pull of the black hole created by the red matter that ultimately destroyed Nero's ship.
