Hi to all.
BN rookie here. I wouldn't watch the show at first being a MAJOR John le Carre and Graham Greene fan from way back. I admit, also, as a former denizen of the outer fringes of le Carre's "Secret World", I was harboring some kind of hateful grudge against the show. My wife, the baseball witch, Dogwomanyan got me to watch it on the marathons and we were hooked. Very cool, very sexy and both Michael and Fiona have real chemistry with the rest of the ensemble equally sterling.
Of course, for me Michael's new handler Carla is an homage to le Carre's arch-nemesis, Karla, George Smiley's eternal foe and based on East German Intelligence head Markus Wolf. I liked the clue about Kurdish Arabic and found their info on the Muslim world to track my experiences in the region. Her character is still undeveloped but I would suggest to the producers that they talk to someone with real experience in the field and who's also blonde, like this nice lady here:

That would be New Mexico's newest ex-spook, Valerie Plame-Wilson, who I met a few months back at her book signing in Albuquerque.
I met her husband, Ambassador Joe Wilson, pictured here:

I found out he was from Santa Barbara, so as a native-born Venturan, I asked the one question I'm sure every secret agent fan and foreign policy wonk wants to know.
"What are Joe Wilson's Favorite surf breaks in Ventura and Santa Barbara counties?"
It seems we both agreed Gaviota had a good break but Rincon point was our personal favorite.
I also had another take on Anwar's Fiona character. She reminded me of this film and another fearless Irish girl named Fiona:

Now I wonder if she has a little brother named Wee Jamie?
