  • One of Star Trek's best

  • One of the bests of Trek - easily a (if not THE) TNG favorite of mine....

  • Past enterprise enters a time-rift and alters the present. With a unique insight only Guinan can provide, the Captain realizes the only way to set things right is to return the ship and its crew, to what will surely be its demise.

  • Quotes (6)

    • Castillo: Most everyone calls me "Castillo"... my mother calls me "Richard."
      Tasha: Okay, Castillo.
      Castillo: No... I think maybe I'd like it better if you called me "Richard."
      Tasha: Richard.

    • Guinan: You always drink alone. It wouldn't hurt you to seek out a little...companionship. Worf: I would require a Klingon woman for companionship. Earth females are too fragile.

    • Klingon Commander: Federation ship, surrender your vessel and prepare to be boarded. Picard: That'll be the day.

    • Picard: Let's make sure history never forgets the name...Enterprise.

    • Worf: Prune juice: a warrior's drink!

    Notes (7)

    • The episode won an Emmy Award for¬†Outstanding Sound Editing for a Series.

    • This episode provides a previously unseen glimpse into the development of the Starfleet comm badge. In TOS, communicators were handheld, with a Starfleet insignia embroidered onto the uniform. In the TOS movies, the Starfleet insignia became a badge pinned onto the uniform, while communicators remained handheld. Communicator badges were only first seen in TNG. However, as seen in this episode, although the TOS movie era uniforms (slightly modified) were still used in the time of the Enterprise-C, the Starfleet badge pinned to the uniform had become a communicator as well.

    • In the alternate timeline, although the senior officers wear modified versions of the newer TNG-style uniforms, many extras wear slightly modified versions of the early TNG uniforms.

    • This is the first of only two episodes of Star Trek to feature two different Enterprises. The second is the Star Trek: Enterprise series finale "These Are the Voyages..." in which both the Enterprise NX-01 and the U.S.S. Enterprise NCC-1701-D appear.

    • This is the last episode of the series to feature all nine of the original cast members.

    Trivia (14)

    • In the scene where Lt. Yar requests a transfer to the Enterprise-C from Captain Picard, watch the doors to the Ready Room very closely after Yar enters; they hit and bounce back just slightly.

    • When Lt. Yar is speaking to Lt. Castillo while walking through the ship, she states that the Enterprise-D is the first Galaxy-class warship built by the Federation. However, naval tradition dictates that the class is named after the first ship built of the type. Therefore, if this was the first ship built of its type then it should be an Enterprise-class warship unless they have developed a different naming tradition for starships.

    • In the alternate timeline Picard begins his log entries with "Military log", however his computer monitor uses the term "Captain's Log," which is from the regular timeline.

    • Despite not wearing one even after a uniform change and when everyone else on the Enterprise-C appeared to have one, Lt. Castillo only has a comm badge when he needs to use it.

    • During the first attack by the Klingons on the Enterprise, Riker orders "Fire phasers" and Data acknowledges the order. However operating the weapons systems is the job of the Tactical Officer, not Data the Operations Office. The Tactical Officer remains quiet throughout the engagement and doesn't seem to do anything.
