RORY: You did all this for me.
DEAN: It’s not over yet.
RORY: This is just like that Christmas when I got a full set of illustrated encyclopedias. [Dean gives a confused look] I wanted them.
Another example of Dean and Rory just aren’t on the same page. When she says the experience of the anniversary dinner is just like getting a set of encyclopedias, Dean is confused – to him that means a really boring present. Rory has to explain that getting a full set of illustrated encyclopedias is actually a wonderful thing that made her happy. Apparently all the clues Rory has given him about loving books and knowledge still haven’t quite sunk in.
