Forget the critics on the police procedure stuff when it comes to Castle. Who cares? As a writer, I am only interested in the characters. And last night, when Castle and Beckett were in the isolation chamber due to supposed exposure to radiation, the expressions said it all. Castle wanted to confess his true feelings for Beckett. He was ready, his eyes, his expression showed that he planned to do it...and then they were rudely interrupted...well, to tell them they were not going to die. And the look on Castle's face then, the disappointment, the frustration, wow.
I sure wish I could write that. I'm going to study the DVR until I learn to capture that "look" in words.
