Hey, Castle fans! ABC has released a behind-the-scenes photo of Rick Castle’s dad, who will finally make an appearance on the show in Season 5, Episode 16: “Hunt.”

That’s right! According to TVGuide, James Brolin will not only guest star as Rick Castle’s dad, but will also play an “interesting” and integral part of the kidnapping and rescuing of our darling Alexis.

TVGuide also featured a photo earlier this week of James wearing all black, wielding a weapon. It almost looks like daddy Castle is in full-on war mode. Giving us a glimmer of those alleged CIA skills, grandpa? We’ll just have to wait to see!

Castle Season 5, Episode 16 “Hunt” airs Feb. 25, 2013 on ABC at 10 p.m. ET.
