OK, I spent the whole show excited that they got Joe Morton to play Dr. Wickfield, thinking what a great casting coup... but it wasn't him!! It was Tim Russ. How embarrassing. Still it made me happy for a while. This was a fun episode to be sure, although I was sorry we had to lose Esposito and Ryan (mostly) to make room for the rest of the plot. And my daughter is a senior in high school this year so Castle's interactions with Alexis are definitely hitting home for me. I wish they hadn't bailed on the FBI plotline so soon; I felt like there was more there and it would have been fun to explore it. But I'm glad they haven't fallen into the trap of Castle and Beckett having relationship problems.
