TREK-A-DAY: The Changeling
EPISODE THIRTY-THREE: The Changeling
Well, there’s not really a whole lot to say about this episode. The ship encounters an Earth probe that has merged with an alien probe and crossed their programming. The Earth probe was sent to seek out new life, the alien probe to destroy imperfect soil samples. The result is a murderous satellie that seeks out new life and destroys it if it is “imperfect.”
The action of the episode revolves around the probe Nomad acting as a logic puzzle for Spock and Kirk, who ultimately outsmart the probe and convince it to destroy itself. But not before it kills Scotty (whose stuntman has been getting a tonne of work this season) and revives him, as well as COMPLETELY WIPING UHURA’S BRAIN. But it’s okay, they re-taught her everything she needed to know in a week. Yep.
It’s just not a great episode. The final logic challenge between the probe and Kirk is fun and there’s a cute ending line about how it thought Kirk was its mother, but ultimately it is yet another “something immensely powerful fucks with the crew and kills a bunch of red shirts until they get rid of it” episode. But its not handled as well as Charlie X and thus is just kinda there.
It did, however, lead to one of the greatest Clone High moments of all time, so we can thank it for that. (It happens at 3.38 in the video)
