James Brolin is set to make his grand return to Castle in tonight's episode of the ABC hit drama, but it's not exactly going to be a happy reunion. When a young video store clerk is murdered and his hacker history is revealed, Castle (Nathan Fillion) and Beckett's (Stana Katic) investigation leads them to, you guessed it, Castle's father, Jackson Hunt (Brolin)!
And in an exclusive sneak peek from tonight's outing, "Deep Cover," Kate comes face-to-face with her soon-to-be father-in-law, she just doesn't know it...and Castle doesn't want her to.
Can you say awkward?!
Seriously, how uncomfortable is Castle throughout Beckett's questioning of his CIA agent father, who is acting as Mr. Cross, the CEO of a major company, which happens to have ties to the victim in their case?
And he gets even more antsy when Beckett can't help but ask Cross if they've met before. "You just seem so familiar." Ruh-roh!
To see the Beckett's first (and oh-so-tense) interaction with Castle' father, watch our exclusive sneak peek above.
Castle airs Mondays at 10 p.m. on ABC.
