Castle and Beckett's nuptials may have just gotten a little more complicated.
The Warehouse 13 alum, whose credits also include Modern Family and The Mentalist, will play small town hustler Rogan O'Leary who shares a complicated past with Beckett (Stana Katic), according to TVLine. Could he play spolier at the (presumed) wedding?
McClintock first announced his casting on Instagam
