I hope Alicia goes back to Peter and they live happily ever after. But that is just me selfishly wanting to see more of Chris Noth.
I haven't seen the show for a while - got hijacked by Downton Abbey and then didn't get back into the habit until a couple weeks ago - so I'm not terribly invested in the characters like I was once. i do think that Alicial will go with Cary when he makes the break and am up in the air about whether Robyn or Kalinda join them. It would make another "happy family" if Kalinda goes with them but no drama.
Either way, more Chris Noth, please!!!
