Just finished season 6
Went back and watched episode 1 again
Did anyone ever like Toby? I feel like I did for a while but I remember hating him at the start. He manipulates her when she sets boundaries into going at his pace all the time. Yes Kevin is often the third person in the marriage but without her family, Kate would have lost herself completely to Toby's dominant personality and controlling ways.
Also on a Kate theme what happened to the British husband at the end? He wasn't there for Rebecca's passing, was it implied that they split?
