In Like Flynn
We had to time-travel back to the 1940s to get an extended look at what Castle and Beckett would look like as a couple. They went by the names Joe Flynn and Vera Mulqueen back in the days when a necklace called the Blue Butterfly was at the center of a twisting tale of passion, deception and murder. Castle believes that Joe and Veraβs love story is the stuff dreams are made of. If only he could be like Flynn with Beckett already.
