The Enterprise is ordered to undergo a series of tests and fine tuning designed to increase the efficiency and speed of their warp engines, but Riker and the chief engineer have serious misgivings. It turns out that the equations really are bogus, and that it's Kosinksi's assistant, "The Traveler" who is really tweaking the engines using undisclosed methods. Something goes wrong when the assistant lets Wesley touch the axillary controls and the Enterprise is flung first far away, and then into another dimension altogether. The adults finally figure out that the assistant is behind it all, as Wesley tried to tell them, and The Traveler sacrifices himself to get them back home.
Wesleeeeeey! This episode is all about him, and I have a soft spot for coming of age genius characters. This episode certainly hits on that feeling that all teenagers have, that adults never listen to them no matter how important it is. "Not right now, Wesley," Riker tells him when he tries to draw their attention to the real architect of their adventure, the assistant - who, by the way, sounds like John Malchovich even though it's Eric Menyuk. And Kosinski? Totally Dr. Kroger from Monk (Stanley Kamel).
While we're talking about famous actors, omg Wil Wheaton! He's so young!
Ahem. So, the episode. The Traveler tells Picard that Wesley is a genius and should be encouraged, and all the adults are sorry for treating Wesley like a stupid kid. He's even made an ensign and allowed on the bridge again! But, have the adults really learned their lesson? Guess we'll find out in upcoming episodes.
