Fortunately Reston's nausea does not last long, and he and Navidson can spend the rest of the day pushing deeper and deeper into the labyrinth.

Initially, they follow the scant remains of the first team and then continue on by following their instincts. Based on the fact that there was very little evidence of the first team's descent remaining on the stairs, Navidson determines that the neon markers and fishing line last at most six days before they are entirely consumed by the house.

When they finally make camp, both men are disheartened and exhausted. Nevertheless, each agrees to alternately serve as watch. Navidson takes the first shift, spending his time removing the dark blotched gauze around his toes—clearly a painful process—before reapplying ointment and a fresh dressing. Reston spends his time tinkering with his chair and the mount on the Arriflex.

Except for their own restlessness, neither one hears anything during the night.

Toward the end of their second day inside (making this the ninth day since Holloway's team set out into the house), both men seem uncertain whether to continue or return.

It is only as they are making camp for the second night that Navidson hears something. A voice, maybe a cry, but so fleeting were it not for Reston's confirmation, it probably would have been shrugged off as just a high note of the imagination.

Leaving most of their equipment behind, the two men head out in pursuit of the sound. For forty minutes they hear nothing and are about to give up when their ears are again rewarded with another distant cry. Based on the rapidly changing video time stamp, we can see another three hours passes as they weave in and out of more rooms and corridors, often moving very quickly, though never failing to mark their course with neon arrows and ample amounts of fishing line.

At one point, Navidson manages to get Tom on the radio, only to leam that there is something the matter with Karen. Unfortunately, the signal decays before he can get more details. Finally, Reston stops his wheelchair and jabs a finger at a wall. On Hi 8, we witness his gruff assertion: "How we get through it, I don't have a clue. But that crying's coming from the other side."
