Is Castle New Tonight, Monday, Dec. 10, 2012?

After riding out last week’s Caskett Christmas high, it’s time to get back to reality. Brace yourself, Castle fans: Our favorite show isn’t new tonight.

Castle and Beckett are taking a few weeks off during the show’s winter hiatus, but don’t fret — our favorite show returns in a few weeks on Jan. 7, 2013.

And in the new year, things are heating up; in fact, they’ll be red hot when Rick’s ex-wife, Meredith, drops by! As seen in the dramatic promo for Castle Season 5, Episode 10: “Significant Others,” both Kate and Mere will be shacking up with Castle — and no one is happy about it.

The next episode will also feature warring ex-lovers — played by Weeds’ Brendan Ford and General Hospital’s Nancy Lee Grahn — which is sure to make the episode even crazier!

But for now, we’ll be watching that 20-second promo on repeat. What will you do to cope with your Castle-less Monday? Tell us below!

Original Air Date: Castle Season 5, Episode 10: “Significant Others” airs on Monday, Jan. 7, 2013 at 10 p.m. ET on ABC.
