Deanna Troi was a half-Betazoid, half-Human Starfleet officer. Under the command of Captain Jean-Luc Picard, she served as ship's counselor aboard the USS Enterprise-D and the USS Enterprise-E. In 2379, Troi transferred to the USS Titan. (Star Trek: The Next Generation; Star Trek Nemesis)
A great scene, nice for the cast to get a chance to be funny. Certainly some of the real Marina Sirtis being brought to her character!
