This was an outsanding episode. From the moment Laney said that the case might be connected to Beckett's murder I was engulfed into the episode. I love how they have used this subtle story in the background and brought it to the forefront of a random case in a random episode.
So many twists as well, in this. I was feeling really tense when they got to the parking lot as arranged thinking the killer would be unveiled finally, but to have Richard as the hitman? PERFECT twist, and something I really did not pick up on; him saying "her killer".
Great episode that had me in tears by the end, of sadness and frustration to the fact that Kate was so close but lost him.
Genuis writing, really is.
