Elle's Sorority sisters band together to help Elle out when they realize she's serious about getting into law school. They study late with her, act as quiz masters for her, and throw a huge party when her qualifying grades are announced.
Professor Stromwell: If you're gonna let one stupid prick ruin your life, you're not the girl I thought you were.
At one point in the film, Elle overhears her friend David being cruelly rejected by an Alpha Bitch he was asking out. Knowing how sweet he's been to her up to that point, she takes this opportunity to repay him by pretending to be his spurned girlfriend in front of the other girl to help make him look impressive, and it works. He also helps her represent Brooke at the trial by researching the laws on students defending a client.
Elle's graduation speech at the end of the film, which shows how much she matured during the film and the Time Skip. But as the very last bit shows, she's still the same happy-go-lucky Elle Woods.
Elle: "Congratulations, Class of 2004. *flashes big, goofy smile* We did it!!!
The simple fact that Kyle, the handsome delivery man, is so obviously interested in Paulette, a woman who's self-worth could not be more low. By the Time Skip, they're married and she is expecting their first child who will be named after Elle.
Elle's sorority sisters come to see her in her trial and are super excited to be there, eagerly showing up on their own free will. After how shallow these girls were portrayed throughout the movie, you can tell at this point that they really are Elle's true friends. Doubles as a Crowning Moment of Funny.
You see Elle's parents applauding her at the end. It shows that, despite them not thinking she's serious enough for law school, they're super proud of their daughter for graduating from Harvard.
It's also possible to see Enid among the students. This implies that Enid too warmed up to Elle and possibly became friends with her.
Elle telling her mom she got the internship - "Look at my name in black and white! Your daughter's doing something right!"
Some theatre groups that do the show add a moment between Vivienne and Elle during "So Much Better," when both are so ecstatic about getting the internship that they hug each other! Before Vivenne's Heel–Face Turn, no less!
Elle and Emmett - "You were the best thing about this place..." and the rest of "Legally Blonde."
While most of the song is a Tear Jerker, there's a subtle heartwarming moment to it: after Callahan sexually harasses her, revealing that this is the only reason he made her an intern in the first place, and due to a misunderstanding Warner accuses her of sleeping her way to the top (and Vivienne, who knows what actually happened, remains silent at that point), Elle is devastated...but she at least trusts Emmet enough to give him a heartfelt thank you for his help, say goodbye to him and know that he won't judge her as harshly as the others. And she's right.
The song "Legally Blonde Remix" in its entirety. Where to begin? First we get Vivienne admitting that she's wrong and making up with Elle, which was great. Elle decides to be herself in her truly awesome pink suit. Then Paulette gets her Irish Step Dancing UPS Man - It Makes Sense in Context, I swear! Then Brooke fires Callahan and hires Elle... That scene is one moment of heartwarming after another!
Vivienne telling Elle to get back in that courtroom and kick ass, because she can. (Also, she has the best frickin' shoes.)
