Will a revelation of Castle whereabouts cause a rift in his marriage to Beckett and just how far can the family fair with the state of change surrounding them daily and just how will New York famous family adapt with all this in this new season.
The opening murder scene had just the right mix of mystery and shock value without having to be gory. That's an art few shows can pull off, and I appreciate how well they did it here.
Given all that had transpired between the two over the course of eight seasons, it's reasonable to suggest that Castle itself was really a love story built inside the framework of a typical procedural.
