Salem’s “Children Be Afraid” is a mixed bag of action and intrigue as Increase Mather’s (Stephen Lang) witch hunt continues, wreaking havoc and stirring up more tension among the Salem townspeople. Meanwhile, Mary Sibley (Janet Montgomery), Tituba (Ashley Madekwe), and Mercy Lewis (Elise Eberle) rush to find a solution in dealing with George Sibley (Michael Mulheren), who will be the coven’s demise should he awaken from his coma-like state. With so many critical moments this week, it’s a pleasant surprise to find some lighter scenes in between the darker ones.
