At first it was hard to see the relevance of the dead body for NCIS LA. At first it felt like Callen was bored and needed something to do, so he took the case from the rangers...
I felt sorry for the dead woman, she couldn't cope with the normal, uneventful life. I could understand the husband giving up on him too... Poor woman spotted spy-messages and told about them to the wrong person...
It took a while for the team to figure out how the messages were exchanged, I loved the JAG-intro and the return of Harm.
It was a really nice touch to have him fly again...
I watched the 2 episodes together, I don't remember where the first episode ended and the 2nd started. So I'm going to comment about the case under the next episode to stay on the safe side...
