Exclusive Castle Sneak Peek: Castle and Beckett Booze It Up

This season of Castle has been a serious roller-coaster ride that recently hit a fresh peak, with Beckett (Stana Katic) moving back in with Castle (Nathan Fillion) so the two can go after LokSat together.

But the couple moving back in together doesn't just mean a joining of forces. It also means the rekindled magic of Beckett and Castle banter, as seen in the the exclusive clip above from Monday's episode.

Castle Exclusive: even the Russians are upset about Castle and Beckett being apart.

Castle airs Mondays at 10/9c on ABC.
