Castle recently wrapped the first half of its current run with the episode "Cuffed," which found Castle (Fillion) and Beckett (Katic) handcuffed together with no recollection of how they got there. The crime drama returns with the second half of season 4 on Jan. 9.

When Katic spoke to THR in early November, she teased that in an upcoming episode of the show, viewers would finally "see Ryan finally get married" to Jenny.

Castle airs Mondays at 10 p.m. on ABC.
