[Lorelai sees Rory across the gym, and she walks over to her]
LORELAI: Rory, what happened? Where did you go? [sees that Rory is crying] Oh, Rory, honey! Oh.
[Lorelai and Rory hug while Kirk runs around the gym with the trophy]
Despite ruining Lorelai’s chances of winning, Lorelai only thinks of comforting her daughter when she sees how upset Rory is. Nothing stops Kirk’s victory lap – he has no problems celebrating as a teenage girl sobs in her mother’s arms!
Kirk’s dance partner is Donna Delain, who he has danced with for the past five years. She is presumably a good friend, or possibly a relative, but we never hear of her again. Kirk does not include Donna in the celebrations, and he keeps the trophy, even though her dancing has helped him to win! Also note that Kirk is wearing a Doose’s Market logo on his back – perhaps Taylor is sponsoring him?
