One of the best episodes. A big fan of Leonard Nimoy`s Spock,here we see a different aspect of him as a Vulcan. Was it written by a woman I wonder. Loved the depth of emotion between spock and Zarabeth. Brilliant. Great series and films.

I grew up with this series. As Leonard from the big bang series said ' original series over TNG and Picard over Kirk'. Brilliant series. Way, way ahead of it's time.
