Em and the others were shocked to run into a pig. Desperate for food, the kids made the instant decision to kill it, but it escaped, biting Latu in the shoulder and badly wounding her as it did. Against Em’s orders, Bishop ran after the pig, leaving Em no choice but to follow him. They tracked the wounded animal to a room with something the kids have never seen before — plants, a dense thicket wall. The pig’s blood trail leads through a shallow tunnel gnawed through that thicket, so that’s where Bishop and Em must go.
