Richard Speight Jr. will reprise his role as the trickster god, Loki, in The Winchesters, a prequel series to Supernatural, in which he previously appeared. Showrunner Robbie Thompson said that he was always planning to incorporate Speight into the series and suggested that Loki's return will be surprising for the characters. Set in 1972, The Winchesters follows the early stages of John and Mary Winchester's relationship, with several characters from the original series set to reappear, including Dean Winchester. Despite mixed reviews at first, the show is finding its stride, promising a bright future for the franchise.
