The razor blade - why would Brody make things easy for the fellow who had humiliated him in captivity? would have suffered more if kept alive.
Or is Brody very humane?
(How quickly an hour can pass when you're enjoying the show)
Yes a conclusion is met and there is obviously room for the next season - I was satisfied with the ending, which for me is unusual as nearly all tv/film is so predictable that you feel you wasted your time watching it (or at least I do) but the non obvious twists were worth it! There are however quite a few things not addressed in the season but I am unsure whether that is for the audience to speculate on or whether they will get deeper into it in the next season
Excellent episode tonight, I'm really really enjoying this which is unusual for me. I don't follow who the couple are though (that moved to near the airport). Think I was doing my nails when they first appeared.
