Padmé telling Anakin she's pregnant. His grin absolutely makes it. And then there's the way he reacts when she worries about how they're going to handle it (a perfectly justified worry, considering that Jedi aren't allowed to marry and thus Anakin would be EXPELLED FROM THE ORDER if the Council were to find out.):
Padmé: What are we going to do?!
Anakin: We're not going to worry about it. This is a happy moment, the happiest moment of my life.
This becomes even more so in light of The Clone Wars: The lost Padawan he loves like a sister has returned and will hopefully be back by his side soon (she just has to roll up one last loose end). With Dooku gone, peace will finally return to the Galaxy, the closest thing he has to a family is about to be reunited, and now he's going to be a father? This really is the highest point of his entire life.
The novelization includes an absolutely ADORABLE moment between Anakin and Padmé wherein the former comes to the latter's apartment and inquires as to how she's doing. She responds that "he" keeps kicking, to which a surprised Anakin asks how she knows the baby's a boy since she had asked her medical droid not to "spoil the surprise". Padmé says it's her motherly intuition, then places Anakin's hand on her belly so he can feel their unborn child's kicks for himself. As soon as he does, he teases his wife by remarking that, with a kick that strong, the baby is "definitely a girl". Turns out, of course, that they're BOTH right. And seriously, the idea of ANAKIN freaking SKYWALKER wanting a little girl is just way too sweet!
Shortly before this, during the opening dogfight over Coruscant, Obi-Wan urges Anakin to leave him behind and save himself and Anakin replies "I'm not leaving without you, master". This is likely one of the times Obi-Wan was referring to when he told Luke that his father "was a good friend".
In the novelization, Palpatine attempts several times to make Anakin fall further to the dark side after killing Dooku. He tells him to leave Obi-Wan there, he plays up his fragile old man act so Anakin will have to drop Obi-Wan to his death to save him, he pushes him to kill Grievous by playing on his desire to become a great war hero (lying that he could make it an order), etc. But each time he does this, not only does Anakin refuse out of his friendship with Obi-Wan, he realizes that he does not like Palpatine at all when he makes these suggestions. Their friendship is so great that it almost allows Anakin to see through Sidious's doting old man act.
During the opening battle, when Anakin hears their clone wingmen are taking a battering from droid fighters, he's willing to break off from their mission and help the clones fight off their attackers. Obi-Wan reminds him rescuing the Chancellor is more important and the clones are willingly sacrificing themselves so they can complete their objective, but Anakin is clearly saddened at having to abandon comrades in arms, showing how much appreciation and consideration that he and the rest of the Jedi had come to feel for the clones.
And like the above example with Obi-Wan, the fact that Anakin's empathy for the troops under his command is enough for him to try and prioritize their safety over Palpatine's. It's really a pity that it took the Jedi so long to figure out who Palpatine truly was...
The moment when Anakin asks Obi-Wan's forgiveness for not being a good student. And Obi-Wan praises him. Also a Tear Jerker - it is their last moment as friends... (in life, anyway.)
This moment is even better in the novelization, and doubles as a Tear Jerker, because Anakin somehow senses that in a few days, everything will have changed, and this will be his last chance to say something like this. He sees his master off because he is desperate for his old master not to leave, and because he can feel that he will need his master to show him the way amidst the confusion. The implication is clear: Obi-Wan and Anakin's bond is so strong that, if Obi-Wan didn’t have to leave to take down Grievous and hopefully end the war, everything would have been fine and Palpatine would have lost.
Similarly, after successfully pulling off a landing that Obi-Wan considers to be "textbook impossible," the very first thing Anakin does is to look to Obi-Wan for approval. He just did something that 99% of pilots would've considered a pipe dream, but he doesn't smile and relax until Obi-Wan's "another happy landing" line.
The ending of the novel is brilliant. Each of the chapters has Dark Side-ish introductions, but at the end...
In another one that doubles as a Tear Jerkerand a Call-Forward, Obi-Wan reflecting that he always expected that, when he died, Anakin would be with him.
Near the start of the film, Anakin verbally defends R2-D2 when he thinks Obi-Wan may be (unintentionally) insulting the droid, telling his former Master, "No loose-wire jokes," and declaring that R2-D2 is "Doing his best." It's really heartwarming, especially since we didn't get to see that much of this part of Anakin's personality until The Clone Wars premiered and retroactively presented him with this type of personality.
A subtle one, but after Obi-Wan's duel with Anakin on Mustafar, he returns to Padmé's ship and Threepio is out there waiting for him. When Threepio suggests they should leave, Obi-Wan just gives him a weary pat on the shoulder. It's a small but very touching moment.
Doubles as a call-forward to A New Hope in which Luke gives Threepio a similar pat when the latter is forced to wait outside the Cantina.
The opening of the novelization describes the people of the Republic reeling from the attack on Coruscant and trying to comfort their children. Only, the children don't need comforting. In fact, most of them are reassuring their parents that everything will be all right. For one simple reason; "Anakin and Obi-Wan will be there any minute." Even as the galaxy is slowly turning on the Jedi Order, kids still view its champions as superheroes that will make the bad guys regret getting out of bed in the morning.
Similarly, the Jedi youngling turning to Anakin/Vader as he enters the Council chamber and asking him what to do. From their perspective, they were terrified, but now Master Skywalker is here, and everything's all right. Of course, then the Mood Whiplash hits...
Anakin and Obi-Wan bickering like the Vitriolic Best Buds and Bash Brothers they are after rescuing Palpatine, where Anakin insists that Obi-Wan should hang out with the Senators and Obi-Wan somehow manages to be both snarky and humble at the same time, telling Anakin that he deserves all the credit and to "enjoy his glorious day with the politicians."
Anakin: All right. But you owe me one, and not for saving your skin for the tenth time.
Obi-Wan: Ninth time. That business on Cato Neimodia doesn't...doesn't count.note The Legends novel Labyrinth of Evil describes the event in question. Basically, Obi-Wan accidentally inhales gas during a battle that causes him to go ga-ga. Much to his embarrassment, Hilarity Ensues. Turns out Obi-wan is a Drunken Master with a lightsaber. Guess that explains why he felt comfortable enough to stop for a drink when they chased the bounty hunter Zam Wessel into a bar in Episode II.
Worried by his dreams of Padmé dying, Anakin goes to Yoda. While it's no secret that Yoda's very busy due to the war, he takes the time to listen to Anakin's fears and tries to comfort him. YMMV on how good his advice was, particularly because Anakin is evasively leaving outkey details about his problems, but he took time out of his busy schedule to genuinely try to help Anakin, and that's very kind. It's also touching that despite the tense relationship between Anakin and the council around this time, he genuinely sought out Yoda's advice thinking it would help — even though he wound up not using it.
There’s a very brief scene with Anakin and Padmé sitting together in her apartment and Anakin has his arms around her, with his hand apparently on her pregnant stomach to feel their unborn baby. It’s just a very short but heartwarming scene of them being a happy, normal family before the storm hits.
When Anakin disrupts Mace’s fight with Palpatine, Mace holds out his hand to Anakin to warn him to stay back. One gets the impression that, despite not seeing eye-to-eye with Anakin and clashing with him a lot, Mace still doesn’t want to see him hurt and is trying to protect him from Palpatine. It becomes something of a Tearjerker when the viewer considers what Anakin does to Mace moments later…
It's a subtle moment, but when Obi-Wan comes to see Padme about Anakin after his fall to the Dark Side, Padmé has been told that the Jedi are traitors and criminals, both by her husband and by Palpatine. They should probably be reported to the authorities straight away and not doing so could be seen as an act of treason in itself…and yet Padmé never seemed to even consider turning Obi-Wan in, letting him into her home willingly.
The ending of the film as Luke and Leia are passed on to their adoptive parents, promising that despite all of the evil that has won for now, the galaxy still has a new hope waiting for it.
Bail Organa's words when he offers to adopt Leia. And we know he kept his word and that Leia was Happily Adopted and raised to be the Lady of War we all know and love.
Bail: My wife and I will take the girl. We've always talked about adopting a baby girl. She will be loved with us.
The final shot of the film has Owen and Beru holding baby Luke, as they look at the binary sunset, in a touching Call-Forward to A New Hope.
During the meeting in which they discuss what to do with the twins, Obi-Wan is understandably crestfallen: his Order has fallen and he has had to kill or maim his best friend. But then Yoda tells him he has training for him, training he learned from an old friend who has returned from the netherworld of The Force, Obi’s old master. Obi-Wan’s face lights up in surprise as he gets the first bit of positive news in what has to be days.
Obi-Wan:Qui-Gon?
It's implied in the film, and stated outright in the novelization, that Obi-Wan knew all along that Padmé and Anakin were a couple, but he chose not to say anything due to the fact that she was about the only thing that made him genuinely happy. He then goes on to say that Padme loves Anakin so much her eyes visibly light up at the mention of his name.
Moreover, when he discovers that Padmé is pregnant- and thus his instincts were correct- he reacts not with anger but with compassion and understanding. You can practically feel his heart breaking for her. Definitely a bit of a Tear Jerker as well.
Obi-Wan: Anakin is the father, isn't he? [beat] I'm so sorry.
While the circumstances are tragic, the last thing Obi-Wan says to Anakin before he has no choice but to thoroughly mutilate him is "Don't try it" in a seriously pleading tone. Right up until the very end, Obi-Wan didn't give up on redeeming Anakin.
In fact, throughout the final duel Obi-Wan is constantly trying to break through to Anakin. And his final words?
"You were my brother, Anakin. I loved you."
During the birth of the twins, Obi-Wan ends up taking the newborn Luke and showing him to Padmé. Despite still being in labour and dying, Padme is able to smile and gently touch her son, showing she really did love her children.
