That was a good episode this week. Beckett straddling the line between the law and justice for her mother. And the moment when she sees the crying sister and knows she has to get the killer instead of letting him finish his job.
And I'm with Castle. I would have watched.
And now the Senator thinks he owes Kate a favor. I doubt she would ever cash in on it, but it does open up possibilities.
And does anyone really think the Captain bought Castle's story about Kate just trying to relate the suspect? I don't.
