NCIS - Enemies Domestic

The explosive second half of a brilliant two parter.  This is one of the best episodes of NCIS and just confirms why this is one of the finest television shows on air today. 
The story continues with Director Vance injured, Director David's bodyguard dead and the Israeli MOSSAD leader missing.
It appears the conference has been orchestrated by Vance and David to expose whoever wanted Vance dead on his first NIS (yes, it's not a typo but it was before they put the 'C' in their title!) mission in Amsterdam where he met David.  We went back to 1991 and saw the whole story play out with some fantastic makeup allowing Vance and David to look twenty years younger.  We even got to see Vance and Gibbs meeting for the first time some years later.
One of the highlights was seeing Ziva get into a girl fight with another female MOSSAD agent, in a synagogue no less!
This was another exceptional episode.
