The sheriff approaches Joe Lockhart, who says he still hasn't found "the thing that took [his] Zeke." The sheriff asks if he really believes it. Lockhart says, "Yeah. How many people have to die, Sheriff, before you believe it too?" Could there be a more clichéd line? Well, only every other line in this episode, actually. The sheriff says he feels like he's in "a hole down in the dark somewhere." Lockhart starts to respond but then abruptly cuts off. Cut to Derek narrating that Lockhart immediately knew where the thing was that had killed his son -- right under his feet. But he wasn't going to let the Sheriff go with him. Lockhart fakes a swoon, and when the sheriff comes over to check on him, clocks the sheriff with the butt of his rifle. Now, if he would only do the same to Derek, Jason, and Chloe, we'd be getting somewhere. Lan can stay. I kinda like Lan, minus the whole Derek crush.
Speaking of Lan, she's on the phone, explaining about some letters she found in the Library of Congress. They were from a Civil War soldier and describe an encounter his regiment had with an "enormous creature" that was "within a shallow ravine in the northern heart of the forest" and that it's "underground." In case you didn't get that from the "under his feet" part earlier. Derek realizes that the ravine in question must be near Cassie and Brandon's campsite, since their Pig Hat map included a ravine.
When they get to the campsite, Derek does a quick inventory of the location and then takes off running in one direction. Jason and Chloe aren't quite sure where he went. There are many Blair Witch-esque shots of branches and the ground.
Derek approaches the mouth to a cave. Cut to Derek narrating that he should have waited for Jason and Chloe, but he had to see it. Cut to Derek, entering the cave. Of course, his flashlight goes out. After last week, wouldn't they get new flashlights? The light from his camera illuminates many bones and such on the ground. We see the silhouette of Joe Lockhart, kneeling on the ground up ahead. Derek approaches him. Lockhart turns around and he has some enormous claw marks on his head, and is bleeding profusely. He says, "Best be getting out of here, boy. She's in a bad, bad mood today." Are they kidding me with this dialogue?
