The week-long national syndication window opens for the 22nd episode of Star Trek: The Next Generation. This marks the final appearance of Denise Crosby as series regular Lt. Tasha Yar; the actress has decided to move on to less limited roles. Crosby returns to TNG several times, and later hosts several documentaries on the Star Trek phenomenon. 
Stardate 41601.3: The Enterprise rushes to rescue a shuttlecraft carrying Troi, and the Away Team discovers that Armus, an evil entity, is preventing them from saving Troi and the shuttle pilot. To make sure that its point is clear, Armus kills Tasha Yar and torments Troi and the rest of the crew.
