Castle Season 6 Speculation: Jerry Tyson aka 3XK Returning?

Meanwhile, the actor playing Jerry Tyson aka 3XK, Michael Mosley, is busy filming a new series called "Sirens." The new TV show is slated for 2014 programming on USA network. No future guest appearance on Castle is listed under Mosley's name on IMDB.
