A mini "Grey's Anatomy" reunion is coming to ABC drama "The Catch," with news that T.R. Knight will join the Shonda Rhimes series in a recurring role.



The announcement came on Tuesday that Knight would appear on the show's sophomore season, playing a mysterious role that was "created and written especially for him," according to executive producer and showrunner Allan Heinberg. No other details about the character were provided.



Knight and Rhimes -- who produces "The Catch" under her Shondaland banner -- first worked together on "Grey's Anatomy," the long-running ABC medical procedural on which Knight was an original star. The actor played Dr. George O'Malley, who was killed off in 2009 after five seasons, when he was hit by a bus. Despite that brutal end -- and some behind-the-scenes drama with fellow star Isaiah Washington -- it appears that neither Knight nor Rhimes are holding any grudges, with both stars saying they are thrilled to collaborate onscreen again. (Guess Knight isn't the actor Rhimes admitted to killing off because she didn't like him or her.)



"This has been a thrilling secret to keep!" Rhimes said in a statement. "One of my favorite family members is home!"



"Working with Shonda, Betsy , and Allan again fills me with immense joy," Knight said in his own statement. "I am heartened to be returning to Shondaland and excited to work with this exceptional cast!"



There's no word yet on a premiere date for "The Catch" season two.
