The CW has shifted one of its actor over to Riverdale. It's been confirmed that Sam Witwer will join the cast of the Archie Comic's inspired show in its fourth season as Mr. Chipping. During Comic-Con, Cole Sprouse explained that Jughead will be shipped off to a prep school, or in the actor's words, to a place of "the bane of [Jughead's] existence." Sprouse had this to say about the subplot.

"Jughead gets whisked away on a scholarship to a very sort of Gossip Girl Upper East Side preppy, pretentious, richy-rich silver spoon [school] and he's going to be the new blood...But yeah, I think it's fun. And the school also kind of serves -- I assume, maybe I'm just speaking out of turn here -- but it serves as the setting for the flash-forward."

It seems Sam Witwer will be one of the prestigious school's lecturers, a recurring character known as Mr. Chipping. The news was confirmed with the following official character description:

"Handsome, bookish and cool, Mr. Chipping teaches creative writing at a prestigious prep school near Riverdale. He recruits Jughead for his seminar, and while he's eminently inspiring to his students, there's a darkness hidden far beneath the surface..."

Most fans recognize Witwer from his role as Agent Liberty on The CW's Supergirl, but he has been around comic book and genre world for quite a while. After a series of guest and voice roles, Witwer portrayed the Triton refugee, Crashdown, in the reimagined Battlestar Galactica. He made a name for himself on the small screen as Davis Bloome on Smallville. This eventually led to the starring role in the US version of Being Human where played the vampire with a conscience, Aiden Waite, for its entire 4 season run. He continues to provide his voice to multiple Star Wars video games as Palpatine as well as Maul/Darth Maul in the series Star Wars: Rebels and Star Wars: The Clone Wars and film Solo: A Star Wars Story.

There is no word yet about Witwer's importance to the overall plot of Riverdale, but Sprouse's claim at a flash-forward hints at a new mystery. Season 4 will see our characters' high school years coming to an end, but after a season of serial killers, suicides, secret societies, cults, organ stealing, underground boxing matches and relationship drama, we aren't expecting anything calm or normal from Mr. Chipping.

Riverdale stars KJ Apa, Lili Reinhart, Camila Mendes, Cole Sprouse, Marisol Nichols, Madelaine Petsch, Mark Consuelos, Casey Cott, Charles Melton, Vanessa Morgan, Skeet Ulrich, and Madchen Amick. Kerr Smith (The Fosters) has also been confirmed as a recurring guest star this season. The Final Destination star will play the High School's new principal, Mr. Honey. This season will also feature a special guest appearance from Shannen Doherty in honor of the late Luke Perry.

Season 4 will premier on October 9 on the CW. Check back with us for all of your updates on your CW shows. This news comes to us from
