Janeway's inconsistency drives me crazy
6 June 2019 | by tessarekSee all my reviews

In the beginning of the episode we witness Tom's demotion. I don't want to give away any spoilers, but suffice it to say, he did not violate the Prime Directive. If you really think about it, you will come to the same conclusion. It was merly bending the spirit of the law. Funny fact, the Prime Directive did not even apply in this situation.

Janeway's irrational and overly dramatic punishment for Tom is nothing more than another sign of her holier-than-thou mentality. Otherwise she would have had to demote Tuvok in the first season's episode "Prime Factors" and put him in the brig for longer than 30 days. However, she did not, which only proves my point.

Other than that I really enjoyed this episode, which develops Tom's character even further.
