I agree with the sentiment in this post - Season 2 / Episode 2 may have been the best episode of the entire series. I also agree that there is someone else working on the inside for Nazir, but I don't think it's Saul. The show's writers may be trying a little misdirection by dropping some hints that Saul may be a traitor - the incident with the lie detector test, the suicide of Nazir's lieutenant while in CIA custody, etc. At the end of the day, though, I think the secret traitor will come out of left field.
Two pet peeves about last night's episode:
(1) CIA & JSOC are planning an operation to take out the most wanted man in the world and they are having a conversation over Skype? Seriously? I'm no IT Security expert, but I don't think Skype is the most-secure communications medium. I guess even Homeland
needs product placement revenue
(2) When Brody & the Veep go into the Centcom command center at the Pentagon to watch the Beirut mission, why didn't they have to leave their cellphones outside the room? My understanding is this is standard across defense and intelligence - you cannot bring mobile phones into sensitive areas. I'm sure the writers & producers are aware of this (you can tell the show is very well researched), but Brody had to have some way of tipping off Nazir in such a short window of time.
