N.C.I.S. General Discussion

Should I add  a NCIS forum? I watch the show Too, I dont care for the LA version, but the regular one I have seen all 10 seasons.
I just found out that Cote de Pablo as Ziva David  is /has left the show.
Ep 11x02 was her last ep, she looked odd in it, no reason given for why she left!
I read they are going to intro some new characters, in this season, and one of them will get the regular cast spot.
the roles are like auditions.
Did you see S-1 and 2 with kate??
Those were the best, and she quit the show too, said she was "tired"  too much work.
So I dont know if Cote got tired too or what.
