Rory, fresh from an unresolved argument with Lane over not telling her that her science partner was Dean, now confronts her mother about getting back with Max without telling her. Lorelai says she was just trying to protect her feelings after her break up with Dean, but Rory does not press her on why she felt the need to share Rory’s private life with her on-again off-again boyfriend.
Instead Rory decides to attack her mother for her lack of commitment and constant breaking up with boyfriends after just a couple of months. It seems out of the blue, but in fact Rory must be very angry with her mother for setting her such a poor example when it comes to maintaining relationships. On some level, she must be angry that she couldn’t say “I love you” to Dean, and at least partly blames her mother for that.
