'Homeland' Season 3 Trailer Has Lots Of Sad People

Looks like a lot of healing is going on. Judging from this long, emotionally exhausting trailer, we see that the folks from Homeland are recovering from just about everything that's rocked them over the past two seasons. Brody's family is more or less in mourning, Carrie's heartbroken, Saul is playing his usual Eeyore self, and Brody's a man on the move. I'm not too eager to share my thoughts on the plot of season three because a) who the hell knows, and b) I don't want to spoil anything for those who aren't caught up. So watch the trailer and see if you can make some sense of what's going on.
