I enjoyed the episode. I am curious as to how it plays out next week. I enjoyed the Sam/Callen goofing off and I enjoyed the opening Kensi/Deeks scene with them sparring.
I like most episodes where Granger is around. Though I feel many will probably scoff at the episode because I have found a lot of people bored by the "Mystery" of Hetty. I still enjoyed this though.
Its no worse then the ongoing "who is Callen's father" crap.
