Star Trek: The Next Generation Easter Egg - Tasha Waves Goodbye

Near the end of an episode entitled "Symbiosis" in season one, Tasha Yar (played by Denise Crosby) can be seen waving to the camera far in the background as Picard and Crusher exit the cargo bay. This was Crosby's last scene as a regular on The Next Generation, hence the goodbye wave. The episode in which Tasha was killed, entitled "Skin of Evil," was filmed before "Symbiosis" even though it was obviously aired afterwards.
