'Salem': Mary Issues a Final Warning (Exclusive Video)
THR premieres a scene from Sunday's episode, which features guest star Stephen Lang.
Mary Sibley has had enough on WGN America's Salem.
After discovering that the coven is conspiring behind her back, Mary (Janet Montgomery) -- in a scene from Sunday's episode exclusive to The Hollywood Reporter -- takes matters into her own hands.
In a tense confrontation with Magistrate Hale (Xander Berkeley), Mary lays down the law. After all, it's her who got the witches on the path to achieving the Grand Rite, a point she has no problem making.
"Much worse for you, you underestimated me," Mary says.
"Do you have any idea what you've done?" Hale pleads.
"Question isn't whether I understand what I've done, but whether you understand what you must now do," Mary says in a final warning.
Salem airs Sundays at 10 p.m. on WGN America.
