I'm not the biggest Miranda fan, but I thought her bringing up the problem with Aidan and then backing off perplexed and scared when Carrie reacted so negatively was reminiscent of the best of SATC. Both of them are annoying, but neither is wrong, and the way they dance around the issue is an interesting reflection on the boundaries of their friendship.
Loved Harry finally telling the truth and acknowledging that Charlotte needed to be able to talk to her friends openly; it should have always been obvious but at least now it's out in the open. I also really liked the dynamic of a more-assertive-than-usual Rock very confidently telling big sister Lily to get it together for Charlotte's sake.
I think Seema looks good in anything, but she is very much a powder keg about to explode, however that ends up happening!
