One of my complaints from season 5 was that there was absolutely no mention of the baby at any time during any of the shows, not even the one with the earthquake that had damaged their home. They were trying to keep the show hip and I understand that, but they most certainly could have continued mentioning the baby periodically in the same manner as they did for the season 4 finale.
I am also not sure that he would have been so ready to start dating again only 8 months after Sally died. Those two were very close and I speak from my own experience, that when I lost my husband I was devastated for more than 2 years before I could even remotely start living normally. It was even longer than that before I started to date again and I only did so because I had a young child to raise.
The episode was overall pretty good. A lot of little twists and turns.
