That is what I posted in brackets in my post #25.
Castle was a toss-up for renewal. They had already decided to write Becket and another female character out, if they had another season.
Ironcially, Castle was almost cancelled after the first season. They didn’t. Since then, many episodes have had the highest viewership for the evening. Castle helped save ABC.
Ehhh...not missing much. I will miss the show. Not this season, but prior seasons were quite enjoyable.
