The Alpha pack is coming, and they're not alone in a new sneak peek video for Teen Wolf Season 3, Episode 7: "Currents." Derek (Tyler Hoechlin) learns they've taken Jennifer Blake, his new love interest. Unfortunately, Scott's (Tyler Posey) mentor, Dr. Deaton, has also been snatched. This is all bad news, because Deucalion (Gideon Emery) promises someone will die. He's an Alpha of his word. "They've found a body," Scott tells his friends, but whose? It's not all doom and gloom, though. Allison (Crystal Reed) and Scott are definitely getting close again.
