Jasmine waiting for Aladdin to return her hair piece. Unbeknownst to her, Aladdin was kidnapped by Jafar. She was starting to think he was more than a common thief, but doubt starts to creep in. She apparently feels silly for being fooled, but is too proud to admit it.
Unlike in the original, Genie isnt upset with Aladdin because he told him that hes not going to use his last wish to free him like he promised. Genie even outright states that he doesnt care about the wish... in this version, whats really left Genie heartbroken is what Aladdins become.
Genie: In ten thousand years... I have never called a master a friend
When he retreats to the lamp, it's more that he knows Aladdin really couldn't go back on his word and just needs some time to realize what he's doing. He's right; Aladdin was going to free him because it was the right thing to do. Then Jafar steals the lamp and rubs it. Cue the Oh, Crap! look on Genie's face when realizing "The guy" has him.
Aladdin's second Dark Reprise of "One Jump Ahead", where he admits to himself that constantly lying about being a prince will never work out for him in the long run. And this is after he declared to the Genie that he wouldn't use the last wish to free the latter. Jeez, how he trembles at the last words...
♫ "Riffraff," "Street rat" Would they think that If they look much closer? Still, I can't play a prince here No, sirree Gotta tell the truth, I can't pretend Even if it means this dream will end Even if she walks away from me... ♫
The ashamed look on Genie's face when Dalia recognizes him as her love-interest from before. The way he sees it, he's been exposed as less than human, a glorified, magical slave.
Borders on heartwarming, but the way Genie reacts when Jafar uses his new powers to torture poor Dalia. It may be Jafar torturing her, but Genie feels indirectly responsible for giving him those powers in the first place.
The horrified look (and yell) of Jasmine when she sees the (apparently painful) teleportation of Aladdin at the ends of the earth.
Tears of Joy when we realize that the Genie at the beginning of the story is telling his kids the story of how he became human and free, thanks to the kindness of one master. But it means that Genie and Dalia see Aladdin and Jasmine less often since boat travel takes a lot longer than genie magic.
Of course, in the novelization, it ends in the present with the Genie and his family visiting Aladdin and Jasmine to tell them they are officially making the harbors of Agrabah their new home.
In a real-life example, Gilbert Gottfried (original voice of Iago) has expressed his heartbreak over not being asked to reprise his beloved character, and has taken not-so-subtle shots at the 2019 movie. Fans of Iago and Gottfried himself have shared these sentiments via social media preceding and succeeding the film's release.
