Castle

A former Vampire Diaries star will soon take a bite out of Castle.

Taylor Kinney, beloved by fans of that CW series for his role as Mason Lockwood, will guest star later this season on the latter ABC hit, stopping by as the husband of a character played by Sarah Jane Morris.

Here's the scoop on episode 17: it will be titled "Once Upon a Crime" and feature Morris as the sister of a woman - dressed as Red Riding Hood, the victim of an apparent wolf attack - found dead in Central Park.
