Dr. Alexx Woods. Too bad, she wasn't given enough story line until she was about to leave. KA is a great actress. In fact she is nominated for an Emmy this year. Miami - look what kind of actress you've let go. If only you have given her enough material... My other favorite is Calleigh. She's sweet, smart and tough. I just hope the writers would give her a weakness (or maybe I missed it?) aside from health.
