NCIS: Los Angeles - Absolution

Now this is more like it!  This is the high quality that I have come to expect with the NCIS shows. 
Absolution is the first of a two parter and is a great story but also has some fantastically funny banter between the team members, especially Deeks and Kensi.  Showing how they are growing as a partnership, he asks her to pick him up from his yoga class and act like she is dumping him so he will look good to the women in the class.  At first she plays along telling him it is over, then she hits him with the old one-two by saying he should never have cheated - with her brother!  Fantastic!!  Suffice to say, he strikes out with the girls!
This episode has some background on Hetty.  She was a devastating force when she was a secret agent in the Cold War and has been keeping a man a prisoner in an retirement home disguised as her husband.  He is in a wheelchair and blind (a result of being shot by Hetty) and is in the early stages of Alzheimer's.  He is the link with a book that hold vital information on spies and the international espionage world will do anything to get a hold of it.  One of the hunters is played by Jurgen Prochnow (Das Boot) who threatens to kill Hatty to get the location of the man in the retirement home.  At the end of the episode, Hetty goes to visit the prisoner, only to find him dead!  Is the killer still there?  How will they ever find the book now?  What other secrets is Hetty hiding?
One of the best episodes of NCIS: Los Angeles for some time.
