RORY: What guy?
LORELAI: I don’t know – maybe the guy who hangs out in our trees all day waiting for you to come home?
RORY: Dean does not hang out in trees.
LORELAI: He bashed his head on a branch last week when I came out of the house too quickly.
The first hint from Lorelai that Dean has obsessive or even stalker-ish tendencies toward Rory.
