This marks the first time in seven seasons the bespectacled Asian fellow who works at Luke's has spoken. He says "Hey Luke, I got the turntable. What's next?"
The outfit Emily is wearing at the party in Stars Hollow is one she has worn in several other season 3 episodes "Lorelai's Graduation Day", "Haunted Leg," and "Here Comes the Son".
Rory had the last line of the show. She says "I guess so" in response to Lorelai's "I guess they will just have to read your stuff" line.
When Luke is talking to his meat supplier he says he wants all the hot dogs and hamburgers delivered on Friday for the party. However after Lorelai and Rory leave the diner Saturday morning (because they had just heard of Rory's job offer the previous evening at Friday night dinner) Luke heads to the Inn to see Sookie and tells her that the food is being delivered that day, although it is Saturday and the food should be coming the following Friday.
When Lorelai and Rory are at the diner, Rory opens her coffee cup to put sugar in, she turns the paper and cup and puts the lid on her paper. But when the camera comes back to her, everything has moved.
When Rory is talking with Lorelai about the roller coasters, you notice that there is a stamp on the envelope, then when the shot returns to Rory, the stamp is gone, even though it is still the same envelope.
Lorelai and Rory's last time together, before Rory leaves for Iowa, is similar to the final scene in the pilot episode.
Lorelai is now driving her Jeep again.
This is the first time that Lorelai and Rory are seen ironing clothes.
Logan states that he remembers his graduation, and that he was tipsy and tripped and grabbed Marcia Hadley's gown. But in the last episode of season 6, "Partings", Rory talks to Lorelai after Logan's ceremony and tells her that "Logan looked great, very dignify, he didn't trip, he remembered to wear pants"
When Lorelai enters Weston's she says: "Hi Sue I'm here to pick up the cake", yet the saleswoman doesn't give her anything and she leaves empty-handed.
After the series ended, it was said that Matt Czuchry (Logan) was definitely slated to be part of Season 8, if there had been a Season 8. There weren't many details about the number of episodes he would have been in, nor information on what it would have meant for the Rory/Logan relationship, but many have indicated that the purpose would have been to give them more proper closure with each other.
Notice the scene where Rory is alone in her apartment, packing everything up, and she stops to take a cereal break. When she takes the bowl out and pours the cereal, you can totally tell that she literally pours hardly anything into the bowl. Then she sits down and pretends to be eating intently, but she's basically eating nothing. It's hard to believe she'd go to all the trouble to dig a bowl and spoon out of her packed boxes just for a couple pieces of cereal.
At the end of the episode, after Rory has broken up with Logan, Lorelai comforts her by telling her that one day, she'll meet someone that she'll just know is right for her, and she won't want to hesitate like she had to with Logan's proposal. It's a bit strange that Lorelai would give out advice like this to her daughter, given the fact that she allowed herself to marry Christopher impulsively just 6 months earlier. That was an instance in which Lorelai dived into the marriage without hesitation, and look how poorly it turned out. With that in mind, what she is now telling Rory seems somewhat contradictory, because obviously, acting without hesitating did not work so well for Lorelai.
edit: actually, Lorelai hesitated. After the proposal, she said she wasn't too sure of it, and maybe they should wait. Christopher was the one insisting. So, Lorelai didn't 'just knew it was right'.
Lorelai: Oh, wait, wait, oh shoot.
Richard: What's wrong?
Lorelai: I promised Patty and Babette that I would get lots of extra programs for the re-enactment.
Emily: Well, here, you can have mine.
Emily: Well what, it was hot.
Richard: Sweetheart, I'm sure I can use some of my many contacts to procure as many programs as you need.
This is the first time Richard has used any term of endearment (sweetheart) when speaking or referring to Lorelai. Emily has never referred to her as anything but Lorelai.
While Lorelai is speaking to Rory outside of the diner it can be easily noticed that the same navy blue car passes behind her twice.
Liz tells Luke that they won't put anything on the shelves because TJ made them, but in the season 6 episode "Fight Face," TJ builds wall shelves for Luke's Diner, and Luke seems quite happy with them.
This episode marks the fact that both Rory's high school and college graduations ended with a breakup. With the Chilton graduation, it was Jess, and now, at Yale, it was Logan.
In the scene where Zach tells Lane he's going to be playing guitar for 'Vapor Rub' you can see Lane take the bananas out of the shopping bag twice.
When Lorelai is on stage at KC's there is a sign behind her and to her right that says "BooZoo Barns". In "A Vineyard Valentine" BooZoo Barns and the Cajun Stompers were the zydeco band Lorelai had scheduled to audition to play at her and Luke's June 3rd wedding. Lorelai referred to them as "the last nail in the coffin of June 3rd".
