Castle creator Andrew Marlowe loves his themed episodes as much as the fans. I previously spoiled that season 6 will featuring a nostalgic Saved By The Bell-esque installment. Soap alum Antonio Sabato Jr. is set to guest-star as Ramon Russo, an actor best known for his role on the fictional '90s sitcom 2 Cool For School. Sabato's character is slatted to premiere in the third episode of Castle, "Need To Know".
As the cast of the Saved By the Bell-esque sitcom prepares to reunite for a movie, the Screech-like character is murdered. Enter Castle (Nathan FIllion), Ryan (Seamus Dever) and Esposito (Jon Huertas), who take on the case until a familiar face returns to lead the investigation.
Castle's sixth season premieres Monday, September 23rd @ 10/9c on ABC.
