Insurgents from Hollow Earth resurface in the next episode of "Sanctuary," resulting in a happy reunion and an unexpected betrayal.
Kate Freelander is back on Earth, instead of inside it. (The best part of that news, however, is that Agam Darshi is back on "Sanctuary." I've missed her these past few episodes.) In the sneak peek for "Acolyte," airing at 9 p.m. Dec. 9 on Syfy, Kate and Will (Robin Dunne) interrogate an abnormal who is part of the Hollow Earth team plotting an above-ground attack. As you can see, they get no cooperation.
