'Castle' photos: James Brolin returns as Jackson Hunt in 'Deep Cover'
Castle and Beckett cross paths with Hunt after a young video-store clerk is murdered. It turns out that the man is also a high-level hacker -- one who may have had ties to the world of espionage.
Do the detectives have any clue of who they're about to meet when they go to this office?
Based on this greeting, it's likely that Beckett at least doesn't know.
Castle is having way too much fun with this.
Is Hunt going to give them any information?
Although Castle may be enjoying this encounter ...
Will Beckett feel the same when she finds out who this person of interest is?
"Deep Cover" airs Monday, Jan. 13 on ABC.
