The return of Col. Mann! Though I disliked Gibbs being a guy who would say "I'll call you" and after 4 weeks still not have called.
Impressive that they managed to make every line in that conversation at the crypt about their relationship as well as about the case.
And the team noting that she's not a redhead.
Oh, Director and your past relationship with Gibbs. Bourbon!
Neat trivia about shooting the air to ward off evil spirits evolving into the military volley.
I don't understand why the guy came by to lay flowers at his mother's dismembered remains. Though I suppose people are complicated -- you can love someone and still be relieved at their death (hello, primary caregiver for an elder with dementia? that's intense) even complete with causing said death and dismembering the body.
I thought the whole "getting away with it must have been the shocking part -- and a new career is born" idea was really interesting.
And Natalie was wicked off at the authorization form meeting, so I endorse her being the butcher. (Though it seems a little weird that they wouldn't have gotten a work address for her when they were tracking her down as next-of-kin.)
