Well. Here's what's going on: there are no people at the producers' base camp. But there's a lot of blood all over the place, so something ominous clearly happened. And for some reason, Sabina is lurking around in the production truck. There's a radio, but something's jamming the signal so they can't call for help. Johnny loads up all the supplies he can find and they get out of there. When they get to the camp, the Revealer gives them a gas mask, which everyone finds kind of worrying. They knock the Revealer down and crack it open, but it's apparently operated by clockwork, so it distributes things on a predetermined schedule. It also has a label that says "Behavior/Reward Simulator Test Group C," which isn't good news no matter how you look at it.
For a while, everyone works together to build a giant signal fire, but Sabina puts the fire out two seconds after it's started. So the only real effect is that everyone learns that Johnny has a lighter. Sam finds Miljan's secret notebook, which causes Miljan quite a lot of distress. But Sam can read some of it, so he lets everyone know that in 1927, there was a dangerous group of natives they need to avoid. So that'll come in handy if they find themselves in 1927, which might not be as crazy as it sounds.
Daniel is sad that Irene is so injured, and he wanders into the woods to be unhappy. And it's a good thing he does, because he sees a mysterious tower with a flashing red light! The next day, he, Johnny, Sam, and Joyce (née Carolina) set out to walk what they think will be about ten or fifteen miles to get there. But on the way, they come upon what looks like the site of a giant explosion. In Tunguska? That's crazy!
Oh, and they come up with a flimsy excuse to justify the camera crews all continuing to film everyone. The idea is that they're going to want evidence when they get back to civilization. This doesn't explain what the cameramen eat or where they sleep or anything, but at least it's a nod in the direction of realism.
Previously: Johnny, Sam and Joyce (no longer Carolina) went to the producers' base camp to see what was up.
Now: the base camp has been vacated. There are some blue pieces of paper on the ground, but no one seems interested in examining them. Joyce wants to go back to Irene, but Johnny has the good sense to insist on picking up all the food and water they can find. The people operating the cameras keep doing their jobs, rather than displaying any concern about all their coworkers vanishing and their food being taken in front of their eyes. Johnny finds a producer's notebook, which suggests that Joyce and Johnny have a love story. He's not thrilled by this.
Joyce checks a tent and screams. Johnny runs over, and there's blood all over the place. Clearly, this place has undergone a catastrophe of some sort. Specifically the cheap sort, since it took place off screen. They start to go back to their own camp, and there's a noise from what looks like a mobile production office. Everyone takes tent poles (they're the only weapon available) and investigates. Sabina's inside! Well, that's weird. She sure gets around, huh? She says she doesn't know anything. Aside from her, there's a computer with blood on it and a radio. The existence of the radio distracts them from the lack of bodies. Sabina tries to send a few distress signals, but there's no answer. She says, "Someone's jamming the signal."
Opening credits! They still list Joyce as "Carolina." But they're already committed to keeping the credits unchanged, since various dead and exited people are also still included.
Neeko, Annie, Miljan and Esther are sitting around the campfire. Everyone's mad at Esther for tricking the other crowd into quitting, but she's quite pleased with herself. And then the other crowd appears out of the woods, carrying Irene. Now everyone's yelling at Esther. Even Joyce is mad at Esther for lying, which is a little rich, coming from the person who's been lying to everyone since the first episode. Esther insists that it's not her fault the helicopter didn't show up. It's true; she may have used Irene's injury for her own benefit, but she didn't cause it or make it worse. She just thought other people would be taken out of the game along with Irene. Johnny tells everyone that the panic button is fake. Miljan points out that it worked before, which is a good point. Johnny can't explain that, and he doesn't even try, because the button clearly doesn't work now. He also relates how the producers' base camp is also a wreck. Neeko thinks this could all be a lie, which is not unreasonable at this point. People have been lying to Neeko a lot. Johnny shows him the backpack full of supplies he got at base camp, which goes a long way to justifying his claims. You'd think Neeko could just go look for himself. It might not be a bad idea to go see if they missed any supplies. They might want those tents later on.
