It's also a relief to finally get an Alexis-heavy episode again. She's been largely absent for most of the season, I'd guess because of Molly C. Quinn's academic commitments. It's good to see her featured more again, though I am getting a little tired both of Castle being unjustifiably suspicious/protective of his daughter and of Alexis being so idealized. I mean, I love it that she's such a great person, but sometimes it's a little hagiographic.
She also recently did a Disney Channel movie, I believe, and I kinda guessed that her gaps on Castle were when she was filming that, though it very well may not have been.
Neither my wife or I had any problem with Castle keeping tabs on Alexis anyway, FWIW.
