TAYLOR: Thirty-five going once, thirty-five going twice . . . sold to Kirk for thirty-five dollars.
KIRK: Yes, finally! You know, if it hadn’t have been for me I could’ve had it for twenty-five.
After Andrew withdraws from the bidding, Kirk wins Sookie’s basket, spending ten dollars more because he bid against himself. It seems as if Kirk didn’t really want either the food or Sookie, but simply the joy of winning something.
Sookie is naturally devastated, because Jackson didn’t talk about how he felt, but sulked and took petty revenge against her in public.
