First of all, I am loving all of the conversation that has taken place about Emily thus far. I believe this episode - along with
Rory's Dance - sets the tone as to why Lorelai and Emily cannot put behind all of the baggage of the past. The fault is mutual. Emily has a highly critical and controlling nature which definitely made having her as a mother extremely hard for Lorelai growing up. I don't actually place blame on Lorelai for running away, as I feel it was something necessary for her at that moment as a coping mechanism to being a teenage mother. She needed a different environment. Where I do find fault with Lorelai is letting the relationship with her parents go for such a long time. It was mentioned that they came to visit a few times when she lived in the Independence Inn. We learn in the pilot that Lorelai and Rory only came to Hartford for major holidays. So, after a year or two of Lorelai licking her wounds it would have been good for her to try to forge some sort of relationship with Emily and Richard if for no other reason than for her young daughter to know her family. However, Lorelai and Emily share the characterisitic of being extremely prideful and neither are very good at backing down on their stance.
I think it was very telling that at the beginning of the episode Lorelai hung on to any small act of understanding Emily made. She kept repeating "pudding" when shopping with Emily to remind herself that Emily was indeed making an effort here. She was also very pleased that Emily was listening to her suggestions about Rory's gift. Of course, Emily and Rory's argument at the party brought all of the dysfunction back for her when she finds Rory upset in her room. I love when Rory says she now knows what it was like growing up in the Gilmore house and Lorelai says it's not official until your huddled in the corner eating your hair.

It always interests me that Lorelai is very aware of the differences in her relationship with her parents and Rory's. In her mind, Rory will never be able to truly understand what her childhood was like and really she is correct in that. Rory was raised in a different environment and whenever she experiences her grandparents' control issues it is in short glimpses (the longest glimpse, of course, coming in season 6 when she lives in the pool house). It was heartbreaking at the end when Emily realized how much of Lorelai's life she was not a part of -- I believe much of her regret lived inside of herself at that moment.
I really enjoyed this first "conflict" of the series between Rory and Emily. It is good to see Rory assert herself. She may have picked an inappropriate time to assert herself, but she is just sixteen - that seems fairly normal to me. As far as Emily getting angry with her -- I really felt that is the time where she should have been the adult in the situation and let it go for the time being and accept Rory's apology. Especially as it was Rory's birthday. She did go to a lot of trouble to make a nice party -- but she also pushed the idea of it and went full steam ahead without asking any input from Rory. Showing up at the Stars Hollow party was indeed a gesture that was wonderful -- Rory could feel better about the argument and know her grandparents loved her.
And - of course - I love Luke in this episode! I believe it is the first time in the series where he really shows he is more than a gruff guy who gives Lorelai a hard time about what she eats. His layer of generosity and caring - which become more and more apparent as the series progresses - glimpse out in this episode. The special birthday coffee cake and showing up with ice in order to try to be helpful in his own way were both lovely gestures.
Emily has Luke and Lorelai pegged from day one. She is very perceptive about them throughout the series.
Also, I think it was a brilliant ending to have Lorelai see Rory and Dean out the window and see her wondering how much she knows her daughter as well. Perfection.
