Misha Collins has revealed that Castiel could potentially return to the Supernatural franchise in future episodes of The Winchesters. Although discussions about involving Castiel in The Winchesters season 1 took place, it was unable to become a reality. However, Collins and executive producer Jensen Ackles are open to exploring Castiel's return in subsequent seasons of The Winchesters. As an angel capable of resurrection and time travel, Castiel's appearance could happen at any point, and his previous role as a fan-favorite character makes his potential return all the more exciting for fans.
