Castle | Ausiello in recent weeks has been taunting you with one of his patented asterisk quizzes, about a four-letter word that threatens to keep Rick and Kate apart on Christmas. Now that I have screened Monday’s episode –aka the ABC drama’s first such Yuletide outing –I can say that although many (OK, most?) of you have since solved the asterisk quiz, you do not know the very interesting reason why Beckett’s “*ork” comes into play. I can also tell you the episode features one of the (faint praise alert!) more amusing subplots for Captain Gates; you won’t ever guess with whom Javy spends the holiday; Beckett has very specific instructions about her gift from Castle; and, yes, a “sexy Santa” costume is part of someone’s itinerary. There’s also a fun line where Rick invites Kate over for “a Christmas movie marathon… or some other kind of marathon that makes life wonderful.” The “dead’ Santa” case itself is a bit clunky, but the close of the hour IMO makes up for it. P.S. Did we know that Leslie Hope was a guest star?
