Fans of Netflix's Daredevil have been waiting almost two full years for another season of the superhero series. Although Matt Murdock and his pals did turn up in The Defenders (and Karen had a substantial role on The Punisher Season 1), the third season has yet to hit the web, and details have been relatively scarce. One thing that has been confirmed for Season 3 is the involvement of a character by the name of Sister Maggie, who fans of Marvel Comics know as none other than Matt's mother. Now, we know just who will bring the character to life on the small screen. Joanne Whalley of The White Princess is on board to play Sister Maggie in Daredevil Season 3.
