NCIS: Los Angeles - Standoff

Standoff was a pretty run of the mill episode for NCIS-LA, which usually has a very high standard of show.  Don't get me wrong, there was nothing wrong with the episode, it just wasn't brilliant.
The story is Callen's ex-CIA partner (who was his 'wife' when they were undercover) takes a Naval recruitment centre under siege in order to get Callen's attention, as you do.  Apparently there was no sane way to contact him!  She believed she was being double-crossed by teh FBI regarding an arms shipment.  Other than that, there was not a lot to this episode.  Not bad, but just not great.
