* 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 who had previously fled town because she couldn't deal with the humiliation. 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. As Sam is sitting on the porch lamenting the turn of events, the rapist shows up and proceed to attack her/him again. Sam tells Al, "I think I know the reason I'm here", and 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=]."
* 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.
