Well, those are good points Laura but she still comes across to me as one-dimensional. Even John's observation about her reaction, or lack of it, demonstrates that she can't jump out of her one track no matter what the circumstances.
Maybe it's the emotionless, monotone way she moves through the whole episode that contributes to my feelings. She clearly HAS emotions, otherwise she wouldn't have committed the crime of passion that she did, but she doesn't show them. She's like a robot with no emotion and a single motivation.
Laura that was very profound - i liked your deep thought of the episode and agree with it for the most part - i still didn't like Kay though, but your comments make me sympathize with her a litte (tiny) bit more.
