I like it! :) And I also like these lines from Catherine Madison in the episode Witch as well after she and Amy are back in their own bodies: "How dare you raise your hand to your mother? I gave you birth. I gave up my life so you could drag that worthless carcass around and call it living!"
I'm sure that Robin Riker had a lot of fun bringing Catherine to life, and also did an awesome job with memorizing those lines as well. :)
