Everybody goes to sleep, and so they miss the time-lapse view of some shadowy native action. It is those guys Jahel was talking about! Maybe they should have been nicer to AJ. Maybe it wouldn't matter anyway, though, because apparently these dudes have nothing better to do besides hunt, gather, and steal people's eyeballs for being idiots like some kind of Fetishized Other Neighborhood Watch.
Everybody: "Hey, what are these insane diagrams outside all of our tents, from which AJ's ostracizing has kept him safe? Bone totems and poisonous powders and whatnot."
Jahel: "You know what, I bet it's those dudes I won't stop warning you about."
Everybody: "No, I'm sure it's just fine. It is weird that it's in the shape of eyeballs, though. Like how you keep saying."
Lincoln looks a lot better with his shorter hair and for this episode only, apparently, he will be translating for Jahel. We revisit the basics of what just happened and then that Emilio has vanished. Maybe he's in jail again... you know how he is.
...But no! He is just going blind against some random tree. Jahel cries and thinks probably this has to do with those dudes. They talk about it for awhile, how he just was going to pee and then suddenly he was blind, and Lincoln asks if maybe this is something having to do with the fact that they are in a mysterious rain forest. Just in case, he says, they should head back to the Magus.
Kurt gives Clark a gun first thing, which he immediately uses to kill a warthog that he thinks is a Morcego. Jahel points out that this will make Captain Planet cry and they are all going to end up blinded. Meanwhile, the dudes trash one of AJ's cameras when he's not looking, which is really just a plot reason for everybody to hate him more for no real reason. While everybody flips out about the fact that they are going blind and being hunted like dogs, that little tick-tock countdown in your head that tells you Tess is about to succumb to whatever the thing is this week goes off.
Tess: "My eyes are tingling and I can't see out of them! Perhaps this is related."
BACK ON THE MAGUS
Tess can't even manage to get up the ladder onto the boat without pratfalling all over the place, and everybody acts super worried even though she is a nonstop liability. Feeling jealous of the attention, Lena determines that she too is going blind, and then acts all put off when Lincoln tries to survey the situation by snatching at her eyeballs with his medical training.
