Susan telling her dancing partner how much she loves her father and how she looks forward to the after-camp trip to the wilderness she always took annually with her father and Hecky.
Susan meeting her grandparents and mother for the first time in a long time.
Taking some close sniffs of her Grandfather and noting how she always wants to remember his signature scent of tobacco and peppermint. She is soaking her grandfather as much as possible. And he responds lovingly in kind.
Just that gasp of "Mother!" when she sees her mother; even Maggie greeting her daughter (despite thinking it's the daughter she kept) is shows a lot of excitement and affection like "I missed you so!"
Susan staring at her mother.
My! Are you beautiful!
Sharon's interactions with Mitch.
Ho, ho, ho. Welcome home kiddo.
Hecky and Verbena practically greet her as though she were their beloved niece.
After Susan reveals her identity, she notes how she just wanted to meet her mother, the family hugs her.
Maggie abandoning a day of plans to give Sharon (really Susan) The Talk, social obligations or no, her daughter needs her.
Maureen O'Hara singing "For Now, For Always" is this and a CMOA.
When Mitch thinks that it's time for Susan (really Sharon) to get The Talk, he's uncomfortable, he flusters, he stammers, he babbles, but what doesn't he do? Try to get out of it. Even though he probably figured that Verbina would take care of this (and granted, she probably did), he's going to face this challenge head-on.
Mitch: You can slug me in the eye any time you want.
When Sharon and Susan realize they're twins. Susan drops down on her bed in tears, clutching Maggie's picture. Sharon comes back into the cabin and touches her on the shoulder. Susan then sits up and the girls hug. They then have this exchange:
Sharon: I didn't know what to say.
Susan: Neither did I. (long pause) Golly! Sisters!
Lindsay Lohan version:
The moment when Annie and Hallie realize they're related and Hallie becomes overwhelmed with tears.
Hallie: So if your mom is my mom, and my dad is your dad, and we're both born on October 11, then that means you and I are like sisters.
Annie: Sisters? Hallie, we're like twins! (both hug each other)
More of a tearjerker for this troper, but Hallie on the plane to London praying that her mother will like her. And their first hug, she's so emotional and is only allowed to express it with double meanings.
Hallie: I've missed you so much!
Elizabeth: Oh, I know. It seems like it's been forever.
Hallie: You have no idea.
The scene where her mother is on the phone and Hallie explores her dressing table objects: makeup, perfume, jewelry, crystals, framed pictures. She's probably never been in a grown lady's bedroom before, and it reminds you that she's going to be a woman soon with no one to guide her on how to be one.
The adoration in her face as she watches her mother work, and the joy she gets in being a part of it.
Annie as Hallie exclaiming "Finally!" when she meets her father for the first time.
Chessy's reaction to discovering that "Hallie" was actually Annie, completely falling to pieces. She blurts out in front of Nick that she still remembers the twins' birth weight, and asks if she can hug "Hallie", before rushing off to make food Annie actually likes.
And the flip side: Hallie telling the truth to Elizabeth.
Elizabeth gets the truth out of Hallie in a sweet way, by playfully tickling her.
Elizabeth: Oh, I see, and where might Annie be? Hallie: In Napa, with her father, Nick Parker.
And this bit in the same scene.
Hallie: Because I love you so much, and I want you to love me as me, and not as Annie. Elizabeth: Oh, darling. I've loved you your whole life.
When Chessy meets up with Lizzie after so many years, Chessy greets her with "Hi, you probably don't remember me..." Instead, Lizzie gives her an enthusiastic greeting and a kiss on the cheek.
"I knew I always liked her!"
When Sammy bolts towards Hallie in the hotel elevator after not seeing her for weeks, and she squeals out his name.
When Hallie runs into her father in the hotel lobby. He thinks she's the Annie-Hallie he just saw upstairs, and she plays along with it because they're not ready to reveal themselves yet. But she can't resist stepping forward and giving him a big warm hug, despite the fact that he won't understand that she hasn't seen him in weeks.
The pride in Hallie's voice as she introduces Merideth to Elizabeth: "And this is our mother: Elizabeth James!"
"T-H-E-M. Them. Get the picture?"
The goodbyes as Elizabeth and Annie leave California. How do you say goodbye to the daughter you haven't seen in eleven years, or the sister you just found out you had?
Natasha Richardson's speech at the end of the movie, and Dennis Quaid's response.
Hallie: It took us around thirty seconds after you guys left for us to realize we didn't want to lose you two again. Lizzie: [wide-eyed] We? Nick: We. I made the mistake of not coming after you once, Lizzie. I'm not gonna do that again, no matter how brave you are. Lizzie: And I suppose you expect me to just go weak at the knees and fall into your arms and cry hysterically and say we'll figure this whole thing out, a bi-continental relationship with our daughters being raised here and there and... you and I just picking up where we left off and growing old together and... and... C'mon, Nick, what do you expect? To live happily ever after? Nick: Yes. To all of the above. [tenderly] Except you don't have to cry hysterically. Lizzie: [already in tears] Oh yes I do! [cue "Shut Up" Kiss and truly epic snog]
The name of the score for this particular scene on the movie's soundtrack: "We Actually Did It". It perfectly sums up both the Twins and the audience's feelings during this moment.
The ending montage of photos of Nick and Elizabeth's second marriage are all incredibly adorable, and in a couple of the photos, it shows that Annie and Hallie's parents aren't the only ones who live happily ever after: Martin proposes to Chessy, and judging by her overjoyed reaction, she says "yes".
