I hope so. I want Toby and Kate together. I just keep thinking of the last finale when Toby was lying in bed alone depressed. Also, people say he did not have a wedding ring on in last nights episode.I had the same thought about Tess' situation. I was so glad Kevin filled her in that she's in the same boat as her peers as far as trying to figure things out.
I think Kevin's east coast house might explain the Kate and Toby situation also. It could be relatively new and Kate and Jack flew in earlier than Toby to see Rebecca and Toby stayed behind for work and is now joining the family.
Like a pp, I also wondered about Kate loosing weight. I was thinking the actress may lose a significant amount of weight for the role. I think there was talk of that in the beginning of the series. They would not be able to hide it though as she would be out and about in her real life and be photographed.
