I'm surprised Martha didn't let Meredith have it from the beginning. Sure she didn't want Alexis to get upset. It was her mom by the way. But to let her come in and take over kinda. I don't believe Martha Rodgers would just step aside.
Richard coming home to set her(Meredith) straight was funny. I knew he wouldn't do it.
As others have said, Lainey, and Espo, and Ryan trying to give advice was so cute. Castle and Beckett need to know more about each other. Even though I find my wife has more history she won't tell, and we have been together for 30 years. But it's no deal breaker.
The case at hand, The wife (Leanne Piper) changing her name and hiding was a little odd. I didn't see it coming. And the scene with Walter and Samantha Voss destroying the valuables and Them being arrested after Kate warned them.
