  • Sam leaps into a young Al, who is being tried for the murder of his commanding officer's wife.

    One of my favorite episodes of the entire series. We get to see Al Calavicci as a young man which is interesting, revealing, and humorous at times. We also get an unexpected twist when Al counts down Sam's percentages of successfully completing his mission. My favorite moment of this series is probably when he counts down to zero and we hear Roddy McDowell's voice. Just an overall entertaining episode that also showed how much Sam needed and cared for Al. I think this is more entertaining if you've watched a few episodes first, but this could also serve as a great "introduction episode" to Quantum Leap.moreless

Trivia, Notes, Quotes and Allusions


  • TRIVIA (2)

    • This episode takes place in 1957, and Al comments that in that time he was 23 years old. This would make Al born in 1934, making his "present" age 65 (as the present is referred to as 1999 at this point of the series).

    • This episode suggests that Project Quantum Leap would still exist without Al, although it would be radically different from the Quantum Leap with which we are familiar.

      Such changes include Sam having a different observer (St. John), Ziggy being called "Alpha", and Tina being married to Gooshie.

  • QUOTES (5)

    • Al: It's going up Sam! Ninety-six percent! Ninety-seven! Ninety-eight! Ninety-nine!...
      (Al's voice suddenly changes and Edward St. John now stands where Al had been as Sam turns to the new voice)
      Edward: ...One hundred... a one hundred percent chance that Albert Calavicci will be sent to the gas chamber.

    • Sam: I've changed history. Oh my God, I've killed Al!

    • Sam: But you're married!
      Lisa: Yes, and so is my husband but it hasn't stopped him from landing in every blonde from here to Norway!

    • Sam: This guy's got more women than you do.
      Al: That's funny. That IS funny. That's hysterical. Have you looked in the mirror…you haven't looked in the mirror yet, have you?!

    • Lisa: I love you Bingo.
      Sam: Bingo?
      Lisa: (they kiss) Bingo Bango Bongo!

  • NOTES (5)

    • In this episode, Sam does many unprecedented things:

      -He leaps into Al
      -He leaps into a dream
      -He, through his own confusion, dramatically changes Project Quantum Leap (and successfully changes it back)
      -He leaps young Al into himself

      This is the second and last time Sam leaps into someone who directly is a part of Project Quantum Leap. The first was, of course, when he leaped into himself during Season Three's "The Leap Home".

      Also, Sam's leaping into a dream is possible because he still has some simul-leaping connections with Al, and, while in his friend's body, he doesn't disrupt his state of mind (such as being immediately confused and disorientated when leaping into a stranger).

      Interestingly enough, after this episode, Al seems to have no recollection of leaping as a younger man, disproving the theory of the "leapees" remembering their time in the Waiting Room.

    • Sam tells Al "Success [of the mission] has nothing to do with leaping. You know that!"

      However, throughout the series both Sam and Al have been afraid of Sam getting stuck in a person after failing to complete a leap.

    • This is the second time Charles Rocket has starred in an episode of Quantum Leap. The first episode was season three's A Little Miracle.

    • Though James Walters played the young version of Al physically, Dean Stockwell provided the voice.

    • This episode co-stars Terry Farrell (from Star Trek: DS9). By a stranger coincidence, though perhaps not on purpose, one of the characters is named Commander Riker.
