Castle | Remember (of course you do) how Rick let down Kate by obliging her wishes and not coughing up a Christmas gift? That “oops” will be revisited as the couple celebrates their first Valentine’s Day together. In that February sweeps episode – the same one guest-starring Firefly alum Gina Torres as the star of a Real Housewives-like reality mess – “Castle and Beckett are talking about what they got each other, and there’s a subtle competition between the two of them,” shares show boss Andrew Marlowe. And as Rick strikes to make good on his Yuletide faux pas, “That in and of itself brings its own complications…. Let’s just say that some wild hijinks ensue as he tries to deliver her present.” Hmm, bigger than a breadbox? Or (ahem) tiny enough to fall down a sewer grate?
