TheSupernatural(SPN) prequel seriesThe Winchestershas finally begun airing, and another familiar face is returning to the SPN universe for the new series. PerTV Insider, franchise alumRichard Speight Jr.is set to reprise his role as The Trickster, aka Loki. At this time, there’s no information regarding which specific episode Loki will return.

Speight Jr. is a well-known face to theSupernaturalfandom after he first appeared near the end of the show’s second season. Though he was only known as The Trickster for just a few episodes, his tricks and deceptions became a defining quality of the character. As the series continued, The Trickster’s true identity was revealed to be the archangel Gabriel (and later also confirmed as Loki). GivenSupernatural’s 320+ episode run, Speight had a relatively small recurring role, but it was certainly a memorable one. Beyond acting for the series, Speight Jr. returned in later seasons to direct a handful of episodes.

Executive producer, showrunner, and writerRobbie Thompsontold TV Insider that Speight’s return was inevitable; it was “a question of when, not if.” He expressed his excitement about reading some of the writers' notes, saying, “it felt like [they’d come up with] an opportunity for us to welcome a friend that we’ve seen before, but maybe not in a way that folks are, are expecting.” Thompson has also teased that other familiar characters may return, though it’s currently unclear how many more he and the team have up their sleeves. With hundreds ofSupernaturalepisodes and memorable and integral characters to pull from, anything is possible.

The series starsMeg Donnelly,Drake Rodger,Jojo Fleites,Nida Khurshid,Demetria McKinney,Biana Kajlich, and is narrated by Ackles.
