* Sam sees what seemed to be just a crusty prospector help save his friends, [[http://www.quantumleap-alsplace.com/img/episodeimages/mirrorimage/39.jpg then vanish in a blue light]]. Sam realizes that the old man was a Leaper, and the bartender (God) tells him that that's what ''guardian angels'' do.
* In "Animal Frat," Sam has to stop Vietnam student protesters from blowing up a school building, which wasn't going to be as empty as they thought it would be. One is a particular JerkAss that harasses Sam over the war. When Sam lets it slip his brother Tom died in the war, the JerkAss says he deserved to for being over there. Keep that moment in mind for later on when Sam beats that little punk silly.
** The scene where he thwarts the bombing is itself thrilling, with the normally peaceable Sam pinning the perpetrator to a table to guarantee that they'll all go down if the bomb goes off. But it's hard to fault him for taking this tack.
--> "Are you ready to die tonight, Duck?"
* In "Revenge of the Evil Leaper," after Alia escapes, Zoe intends to kill Sam as a consolation prize. Sam responds with this threat by shooting her with a shotgun.
* Sam getting up and ''walking'' to punch out an abusive orderly in the episode where he's leaped into a double amputee.
* In the episode "Raped", Sam leaps into a rape victim named Katie, who had previously fled town because she couldn't deal with the humiliation and fallout for failing to convince a jury that she had been raped by the town's football hero. Sam and Al think he's there to see to the prosecution of her rapist, only to have him acquitted because he's the mayor's son and all-American football hero. As Sam is sitting on the porch lamenting the turn of events, the rapist shows up and proceeds [[WouldHitAGirl to attack her/him again]]. Sam -- after kicking the rapist in the groin to stun him -- tells Al, "I think I know the reason I'm here", then proceeds to beat the punk within an inch of his life.
** And we get a CrowningMomentOfHeartwarming right afterwards, when the girl's family comes out and sees what happened. The father incredulously asks "You did all this?", to which Sam responds "Well, I ''am'' a [=McBain=]." [[note]]Although the new history is never revealed, it can be presumed that the [[=McBain=]] family has its name restored and that Katie, coming to terms with what happened, is able to live out a reasonably good future, while Kevin, disgraced as his true character is finally exposed, lives his life out in a persistent vegetative state, never again able to attack a woman and his goals dashed because of his criminal behavior.[[/note]]
* In "Future Boy", Sam leaps into an actor who plays the co-star of a 1950s sci-fi TV show, and his mission is to prevent the star from dying or being committed to an asylum because of his belief in time travel. Near the end of the episode, the man straps himself into the machine and fires it up...''and actually starts to leap'', much to Al's shock. The only reason he failed is because he didn't have enough power.
* The HalloweenEpisode was mostly just NightmareFuel, but the climax is, when you think about it, pure awesome. Turns out [[spoiler:that the "Al" we saw throughout the episode was [[DevilInDisguise actually the Devil]], and he's decided that it's time to off TheHero, and sets to strangling Sam. Sam Beckett, however, decides that he's not going to have that, and [[DidYouJustPunchOutCthulhu chokes the devil into oblivion]]]]. Repeat, [[spoiler:''[[AddedAlliterativeAppeal Sam strangles Satan]]'']].
* In "Killin' Time," Sam leaps into Leon Styles, a serial murderer, who escapes from the Waiting Room (and the project as a whole). Eventually, he makes his way back to the project compound-- and runs into Gushie, who's a rather timid, meek guy by nature. Styles demands that Gushie send him back to his own time, to which Gushie replies that it's not possible. Styles response is to point a gun at the base of Gushie's throat and tells him to send him back to his own time or he'll kill him. To which Gushie calmly replies, "Well, you're just gonna have to kill me then."
* In "Private Dancer", Sam letting his hair down and dancing with Debbie Allen's character. Considering how serious and focused he is most episodes, it was refreshing to see him have fun for a few minutes.
* In the season two premiere, Al has to defend the importance of Sam's leaping to a government committee, or their funding will be cut off and even if Sam keeps leaping, it'll be without Al's help. He's convinced their only chance is for Sam to create a change in history far bigger than the single lives he's helped, and at the time he's at now, the best chance is to stop the 1960 U2 Incident. Sam ultimately fails, but then [[spoiler:corrects the leapee's love interest on a practice question for getting a law degree, and she realizes that one mistake would have affected so many answers that she would have failed the exam without his help. Suddenly, Al's hearing changes from the announcement that the project is being shut down, to the woman saying it'll be kept running.]]
* At the end of "What Price, Gloria?" Sam wonders why he hasn't leaped. Al tells him that he wants to get revenge on Buddy for the sexual harassment he's been guilty of the entire episode. Sam pretends to seduce him, [[UnsettlingGenderReveal tells him that he's actually a man]] and punches him out.
* In "The Colour of Truth" the whites-only hospital was refusing to take Sam's granddaughter even though she was bleeding out. Ms Melny, who'd been previously willing to stay on the fence about racial issues, steps up and demands they take her. The hospital staff don't even blink before accepting her.
* In "The Leap Back" Al, having temporarily inherited a few of Sam's characteristics, manages to bust out Sam's classic spin kick.
* "Lee Harvey Oswald" - [[spoiler:leaping out of Oswald and into a Secret Service agent, thus saving the person he was meant to save - ''Jackie'' Kennedy.]]
* The cast as a whole. Scott Bakula for being able to wear dresses with a straight face (the handful of times he leaped into women) and the remainder of the cast for being able to react to this 6-foot tall white guy as though he were a woman, a black man, even a chimpanzee, with nary an indication that they saw him as otherwise, not to mention act completely unaware of Al's presence, even as he snarks at them.
