Yes, it’s November Sweeps, but we’re already looking ahead to December episodes of Fox’s Bones. The cast took photos for EW as they filmed the Dec. 3 hour, inspired by the gamer documentary The King of Kong, and Dec. 10’s Christmas story, which David Boreanaz accurately describes as “a little sick.” (A man dressed as Santa is blown up after a botched bank robbery. Note: This is also the episode that Emily Deschanel’s sister Zooey guest stars as a distant relative of Brennan’s invited to spend the holidays with Bones and her father. Welcome back, Ryan O’Neal.)

Among the things you’ll learn by clicking through our gallery of 15 exclusive shots: David Boreanaz is responsible for most of Booth’s wardrobe, including the socks, “cocky” belt buckle, and occasional homage to Steve McQueen in Bullitt; Emily Deschanel and John Francis Daley are easily entertained.
