Martha is simply wonderful and the more extended air time she gets...the better it is for all of us. Molly Quinn did indeed have her most powerful acting scene of the season when she confronted Kate and revealed her fears about losing her family. Great Alexis scene, and a great pay off later on when family Castle is hugging and she exchanges a thank you look with Kate. I think that was one of Alexis only scenes with Kate and Molly and Stana executed it brilliantly.
I'd almost forgotten about Kate's mother's case. We've not really touched on it yet, so much has happened already this season. Next episode looks like it will be fun!
