RORY: My wrist hurts and I’m grumpy and I just made a total idiot of myself in there so I just wanna go home.
LORELAI: All right, well, I’ll tell Mom, I’ll drive you.
RORY: No, it’s okay. It’s still early. I can catch my regular bus and . . . you go back in.
How can it be early enough that Rory is still able to catch her regular bus home to Stars Hollow? The scene at KC’s Annex showed Rory and Lorelai in Stars Hollow, and dressed for the party. Rory has already taken her regular bus home from school – that’s how she got home in the first place! She can catch a later bus home, maybe one that leaves around 6 or 6.30 pm instead of between 4 and 4.30 pm, but she cannot possibly catch the same bus home.
