* Mayuri's ending. [[spoiler: She tells Okabe that she feels like she had a very important friend but can't remember who it is, and hears this friend's voice telling her to "find happiness" (heavily implied to be Kurisu).]]
** [[spoiler: Okabe begging her not to leave him in both worlds, and her declaring that she never will.]]
* Ruka's ending. [[spoiler: [[YouCantFightFate Okabe gives up trying to save Mayuri]] but in order to give Mayuri some happiness before she dies, he sends Ruka back in time a few days so she can cosplay for Mayuri.]] Doubles as a TearJerker.
** [[spoiler: [[BabiesEverAfter The post-credits CG image.]]]]
* Suzuha's ending, where [[spoiler: she wants Okabe to accompany her to 1975 so she doesn't fail in her mission and hang herself, even though they may both lose their memories and cannot return to the present day]]. He does.
** [[spoiler: In addition, WordOfGod has said that they do indeed end up having a HappyEnding together, despite the ambiguous nature of the ending.]]
* The final CG image [[spoiler: all the primary cast around a cake saying "Congratulations"]]
* In episode 3, Mayuri opens up the microwave mid-experiment, causing it to go haywire and spit out arcs of electricity. Okabe ''immediately'' grabs her and throws them both to the ground, using his body as a shield.
* Many interactions between Okabe and Kurisu in the second half of the TV series, particularly:
** In episode 14, when Kurisu makes a MadScientist impersonation (complete with InsaneLaugh) in order to cheer Okabe up.
*** This is even better when you realize it's [[http://www.youtube.com/watch?v=SbOfCx0RcO8 a shot-for-shot recreation]] of a pose he did from the first episode.
** In episode 22, the whole scene where Okabe [[spoiler: declares his love for Kurisu]].
** When Okabe sees the D-mail from [[spoiler: his future self. Hearing that all the heartache and sacrifice that time travel put them all through is what opened the path to the Stein's Gate timeline.]] "It all meant something," indeed.
** In episode 23, when Okabe meets Kurisu again [[spoiler:after thinking he had lost her forever]]. Doubles as TearJerker.
*** How he saves her. Also a CrowningMomentOfAwesome and a TearJerker. He [[spoiler:''gets himself stabbed'' by her insane father, tranquillises her, and then ''sprays his blood all over her'' so that past him won't see any difference, thus avoiding a potential TemporalParadox.]]
* After everything Okabe's been through, he's finally given hope in Episode 23, when Suzuha [[spoiler:shows him the video of his [[FutureBadass future self]] giving him a pep talk, telling him that all of his suffering wasn't for naught, and reveals that the time machine was named "Christina" after Kurisu. It's all capped with future Okabe revealing the significance of calling the perfect timeline "Steins Gate": nothing at all. He then closes out with "El Psy Congroo", giving Okabe the motivation to realize that all of his stupid behavior and phrasing can become a reality]].
* From episode 24, [[spoiler:Okabe giving Moeka a lab member badge, despite what she had done in several alternate world lines]].
** When Kurisu and Okabe are reunited at the end of episode 24:
--->'''Kurisu:''' "It... it's you. I've been looking everywhere for you. I don't even know how to begin to say what I want to, but..."\\
'''Okabe:''' *talking into his phone* "It's me. The jig is up, she's wise to us. Do what? [[DeclarationOfProtection What do you mean, you want me to protect her? Very well, just never let it be said I don't indulge you people to a fault.]] Yes, I'm aware, and if that's its choice, far be it from me to argue. Alright then, El Psy Congroo."
** And even before they're reunited, [[spoiler: although he bumps into her only a few moments later on the street, hearing the speech Okabe gives, where he discusses how he's made his own peace with the fact that he might never see Kurisu again but is happy as long he's ensured a world where she lives on "doing her thing," is an extremely heartwarming sign of the selfless love he has for her.]]
** The final line in [[BonusEpisode episode 25]], an obvious CallBack to episode 22 [[spoiler:("Close your eyes.")]]
* About half of Kurisu and Okabe's interactions at the barbecue party. [[AwLookTheyReallyDoLoveEachOther She missed him! He got her a present, too!]]
* During the party, [[AboveTheInfluence despite the fact that Kurisu is clearly drunk at the time]], [[InVinoVeritas it's still adorable that she acts far more affectionate towards Okabe, rubbing against his cheeks and getting much more touchy-feely]].
* [[spoiler: The name of future-Kurisu's time machine.]]
* [[spoiler: All the lab mems recalling Okabe despite not really remembering who he is. Special mention goes to Mayuri, who says that saying Okarin makes her feel warm inside.]]
* [[spoiler: Kurisu finally succeeding in bringing Okabe back to the Steins Gate world line.]]
