Every time someone makes a comment like this, drink…

No, that lame twist is no longer likely.

Did you just say that a show has to be crazy and/or bad for you to sit down and pay attention?

1) Yet another possibility. Brody taking advantage of the most likely scenario, that Affi will take his life before revealing too much is enough reason to pass him the razorblade. I believe it was Brody and that's the intention behind it, for whatever motivation. 
Either for his own protection, his revenge or because…

"Unknown internal moles that conveniently tip off the bad guys at the last minute."
They were tipped off when Carrie tailed Faisell, that was long before they even got back on his track. No evidence of a mole. You have to assume they are monitored and whoever is in charge of this noticed the tail.

But Affi would not admit to that. He might not even know that much. He doesn't "work" for Al Nazir directly. That is no connection.

Brody already being a fully-formed terrorist would be the most boring outcome. 
He may be a sleeper, waiting to be activated. That's still one of the most obvious ways for this to develop.

They probably have better job offers and/or are not affordable?

As I already mentioned several times, that's how I remember it.

To be fair, they don't always work the first time around and if you don't double-check, it's a mess. There seem to be quite a few problems with this board.

It was explicitly nine months ago. From the pilot it's not clear, if they kept going, although it seems more like they didn't, recently. Maybe there was someone else. That would create more drama, when Malcolm finds out.

Yes, that makes perfect sense. You are forgiven to mention it twice. ;)

No, it's not. They look nothing alike, except for being both blonde…although apparently half the board would beg to differ.

I need characters I care about. Just the weekly case is not enough. Even if there is a serialized element or the show is a pure serial, it all falls apart if the characters don't bring it (see The Event for the perfect example in my opinion).
Personally, I don't care about these people.

That's entirely possible and my favorite theory. 
Because I don't think it was Saul and hiding the razorblade in the shoe undetected should not be possible. And hopefully there is no mole in the CIA. I think it must have been Brody.
I think that Al Nasir believes that he converted Brody. Affi also believes this and,…

Yeah, that wig looked much better…

You know what? I'm not sure. Because I see this reply at the top of the page and I don't see my previous comment and I don't feel like searching for my original comment.

How they tried to implicate Saul and how to argue against it :
1. "You messed up my rug." (like he might have a thing about (prayer) rugs) - easily just a throw-away line
2. his prayer (which might sound Arabic and which might make you wonder why he prays for someone who tortured Brody (allegedly?) for years) - he is…

I think it's embarassing that you think being an adult is the reason for being embarassed watching a zombie show…

"(I'm continually flabbergasted when Aliens gets more props than the Ridley Scott-directed original, which IMO is superior in every way. But that's another debate entirely.)"
Between this and your view on Lost and this type of show, I feel on the same wave length with you.
