What can you tell me about Castle’s midseason finale? Will it deal with Castle’s disappearance at all? — Caleb

Executive producer David Amann suggests that the writers won’t be picking up that mystery again until probably February, during this season’s big two-parter episode. But the midseason finale should pack plenty of punch. Because it serves as this season’s Christmas episode, it has a bit of a lighter touch…right up until the end. “We’re looking at a bit of a game-changer for Castle at the end of the episode,” Amann teases, although he promises that Castle and Beckett aren’t getting a quickie divorce. “The events of the episode will cause a shift…in Castle’s life in a fairly significant way.” Bah humbug! (Also, guesses?)
