Star Trek The Next Generation - Vol. 4.2 [VHS] [1990]

After reading the preview of "LEGACY", I was keen to compare Ishara Yar with her sister, Tasha, when I got to see the episode. There was definitely a resemblance between the two. The Yars came from a colony on Turkana IV where constant fighting between the two factions was a fact of life. Due to these circumstances, these two girls became warriors themselves, learning to fight to the end for their cause. Unfortunately, Ishara's cause was one of hate. Tasha was killed in "Skin of Evil" three years earlier.
The Enterprise enters orbit around Turkana IV to rescue two Starfleet crewmen who have crashed landed on the planet. Great caution is taken due to the constant war going on between the Alliance and the Coalition. The away team meet Ishara and Data is especially interested to hear her opinion of Tasha. Ishara tells the crew that she thought that Tasha was a coward for running away from the fight, but Picard strikes back explaining that he has never met a more courageous woman than Tasha.
Doctor Crusher performs an operation on Ishara that will allow her to enter into enemy territory in order for the away team to recover their missing crew. But Ishara betrays them and turns off the oppositions defenses in order for her party to enter their territory.
The best part for me was in the last scene where Data speaks to Riker about trust and explains how Ishara betrayed his trust. Riker explains that despite the risk involved with trusting someone, he is still willing to put himself out everytime.

"REMEMBER ME" puts Doctor Crusher under pressure once again where she is forced to think her way out of a problem that she's in.
Wesley's warp bubble experiment turns hostile when his mother is caught in the experiment and transferred into another reality where the crew begin to disappear.
Slowly the crew count becomes less and less, until it's only Crusher left on the ship. After doing some research she realizes that she is caught in this bubble and that it is collapsing. Meanwhile in our reality, the Traveler appears in Engineering and assists Wesley in retrieving his mother from the warp bubble before it completely collapses and kills her.
The Traveler will eventually be the one who convinces Wesley to leave Starfleet and seek his fortune elsewhere in "Journey's End".
It's not very often that the women of Star Trek (before Voyager) get put in pressure situations, so I was glad when this episode was made.
