I've been thinking of classic showdowns on Knots that stick in my mind. My favourite is Abby and Karen's final scene. With all the years of animosity between them, there was a lot of stuff that could have been dragged up. But I think they did it perfectly. Karen references the key ones: stealing Gary, trying to steal Meg and cheating her out of Lotus Point, but the scene ends perfectly - Abby getting emotional and asking for a favor was a lovely curve ball that managed to touch Karen, and Abby's final half-smile as she goes out the door was great too. I've come up with a poll of the major ones. Which one comes top for you?
