Darth Vader may return in the season finale of Star Wars Rebels, if the last seconds of the video above from the official Disney XD YouTube channel is any indication.

The finale, “It All Comes Down to This,” will air March 2 on Disney XD. If the video’s tease proves accurate, it will mark the Sith Lord’s second appearance in the animated series. James Earl Jones reprised his role in an expanded version of the hour-long premier, “Spark of the Rebellion,” when it re-aired on ABC last October.

Star Wars Rebels premiered last fall as part of the science fiction universe’s newly codified canon, which Lucasfilm announced last year. Set around the time of the original Star Wars trilogy, other characters from that era have appeared and been voiced by their original actors, including Frank Oz as Yoda and Billy Dee Williams as Lando Calrissian.
