I wanted to say that I kept on laughing at "After Hours". It was totally not about the murder about the priest although I missed the first part of the episode. The whole cliche of the witness being the hit man seemed kind of worn out. Castle and Beckett keep on ragging at each other and it is very enjoyable.
I thought the best part was the end when Castle realizes that his mother is quite friendly with Beckett's father and his reaction to that.
