DEAN: This is my town, I’m not hiding. And I don’t have be remotely calm around you anymore, and I like that feeling. I like it a lot. Happy Thanksgiving, Jess.
Dean arrived in Stars Hollow only a year before Jess did, and Jess has family connections in the town, yet Dean now takes possession of the town – it’s his town, and Jess is the interloper. He warns Jess in no uncertain terms that he is not going to gracefully step aside and give Rory and Jess the space they need to form a good relationship.
I don’t think Jess did have a good Thanksgiving, really. He only saw his girlfriend for a short time, and she was too shy to give him more than a peck. When she came back, it was just to kiss him and say, “Later”. Both his girlfriend’s mother and his girlfriend’s ex-boyfriend have let him know he’s been watched by them. And he gets stuck with garbage duty.
Dean’s Thanksgiving wasn’t great either. He has no girlfriend, he had to work on Thanksgiving, and may have taken the shift to avoid his family, because he either hasn’t told them about Rory yet, or doesn’t want their pity.
Rory and Lorelai have a pretty rotten Thanksgiving as well, and Sookie’s is a nightmare. Only Lane and Dave have a happy Thanksgiving in this episode, and it’s about time Lane gets a happy story line!
