Castle Fall Finale Sneak Peek: Kate Ponders Second Anniversary Plans...?

The sheets have barely cooled from her and Rick’s carefully negotiated first wedding anniversary celebration, and already Castle‘s Kate has designs on next year?

In this Monday’s fall finale, titled “Mr. & Mrs. Castle” and airing at 10/9c on ABC, Castle and Beckett investigate the murder of a cruise ship entertainer, and thus are aboard the docked vessel, digging up clues, in the above sneak peek. After Rick channels his inner Jack Dawson, he and Kate wind up wondering if their second anniversary could possibly compare to their recent and torrid “time out from the time out.”

And based on a final twist in the clip above, they may have plenty of “alone” time to further that discussion!
