In order to catch the malicious time-shifting aliens, Picard and some crew-members use their knowledge of their time-travel technique to follow Data and the still unexperienced Guinan on Earth in the 19th century, where author Dr. Samuel Clemens' persistent inquisitive suspicion is on to them. When the aliens' time-shift back is tested, Samuel Clemens is transported back aboard with the crew and starts pondering the advances made in five centuries of human and intergalactic progress, while Data is only retrieved after decapitation.

Samuel Clemens: You got any passions, boy, any dreams?
Jack London: Well, I'd like to do some traveling, maybe go to sea. And Alaska - I've had the strangest notion to go see Alaska!
Samuel Clemens: That's a great idea, son, that's exactly what I would do if I were your age. Alaska, the Klondike, the aurora borealis, that's it! Follow your dreams, and write about them.
Jack London: Thank you, Mr. Clemens. You know, that is exactly what I'm gonna do.

Unexplained time gap
31 July 2016 | by (United States) – See all my reviews

Time travel episodes usually are annoying because they depend on logically impossible cyclical relations, as this one does. However, given that violation of logic, this episode does a good job of remaining logically consistent within its particular logically impossible structure, so it is entertaining and draws the viewer in to wonder what comes next.

One thing, though, seems inexplicable. Where did Deanna pick up such a great tan between the end of Part 1 and the beginning of Part 2? Compare her appearance at 8:45 in Part 1 with her appearance at 30:25 or 35:30 in Part 2. There seems to be a time gap in the plot where unexplained events transpire. Harrumph. Well, maybe it's just the effect of waves on Betazoid melanin. Harrumph.
