Episode cast overview:
Rickey D'Shon Collins ...


While the Enterprise makes an astronomical study of a 87 million year old rogue comet, it discovers a ship-like construction, possibly the nucleus, which contains alien artifacts constituting the 'archive' of an Ancient culture. From then on the aliens take over, 'possessing' Data's positronic network to give him several of their personalities, including the talkative Ehad and the feared queen Musaka. Alas they also transform matter and even genetics aboard, so as to turn the ship into a city their style. Picard resolves to stop that by understanding and playing the key alien characters.

Did You Know?


Director Robert Wiemer is also not fond of this episode. He said: "I always look to find a meaningful subtext of some kind in all the shows I do. More often than not they're little morality plays. I didn't find that here. It ended up an exotic adventure story but it didn't have any heart." See more »


While the comet is being described as a "rogue comet" (which means not bound to any one star system) the on-screen graphic shows it being in an elliptical orbit. See more »


[first lines]
Counselor Deanna Troi: How's it going, Data?
Lt. Cmdr. Data: I have finished. The dimensions are accurate to within 1.3%.
Counselor Deanna Troi: I'm sure they are.
Counselor Deanna Troi: Data, you obviously don't have a problem with realism. But, you're here to work on your imagination. Maybe you should try something a little more... abstract. Here.

Counselor Deanna Troi: I want you to start a new piece. I'd like you to sculpt...
Counselor Deanna Troi: Music.

No Earthly Sense
13 October 2014 | by (United States) – See all my reviews

Somehow, an Aztec-like culture invades the enterprise. They start by transporting artifacts and then use Data as a conduit to express their purposes. Why go through this whole complex procedure. Why not just do their will. Data begins to exhibit multiple personalities and Picard carries on discourse with him in an attempt to figure out what is going on. At least the Captain has been shown to be a true student of archaeology, a cosmic interpreter of mythology, an intergalactic Joseph Campbell. This gives him some sort of credibility. However, the whole thing bogs down when the creature/creatures become true forces. The solution is so simplistic. The conclusion is the worst of any episode I've seen. Watch at your own risk, although Brent Spiner is quite wonderful with his use of voices and his physicality. His Commander Data is one of the most entertaining and creative characters in all of science fiction.
