Right.
I think Aisha (sp?) isn't really Abu N's son. Abu N 'adopted' him and made Brody teach him to get Brody emotionally attached to the kid.
Abu N then had the school blown up and the kid killed. Then he made Brody watch the American TV broadcast of the vice-president saying (truthfully) that the explosion was nothing to do with the US. He turned Brody by exploiting B's attachment to the kid and making him believe that the US was responsible for the explosion and that the vice-pres was lying and therefore Brody must become a war hero and be pursued by cynical American political operators to run for some kind of office. From the inside he will then assassinate the vice-pres (who is of course now running for president).
His hair and beard had grown again and he looked terrible and terrified because, after the explosion (which was three years ago e.g. five years into his imprisonment), he was put back in the hole, with his agreement, so that he'd have plenty of time to grow his hair and look manky again before the Americans were allowed to find him. This accounts for the final three years of his detainment.
I think Saul is a bad lot, although I don't yet know how/why. I love him a little bit regardless.
Mike may also be a bad lot.
Estes is clueless.
Brody's wife, as someone has said, has one facial expression. She's v v annoying.
Damien L looks like a piranha.
I have a mini girl crush on Claire Danes and her huge eyes, her cheekbones, her lovely slim-fitting suits and her toned upper arms.
