RORY: Let’s go …Wedding dress shopping …
LORELAI: Uh, you need to see Dean.
RORY: He’s playing softball.
We know from Christopher Returns that Dean plays softball on Saturday mornings, so this looks to be the very next day after the previous episode, and the fight that Rory had with her grandfather. Rory doesn’t seem to be upset any more, so perhaps her grandfather rang her almost immediately after she got home to apologise, as Emily told him to.
