To prepare for their bonding ceremony, Noa travelled to the Top Nest (a tall decaying building with a few eagle nests) with Soona and Anaya, the latter showing off his climbing skills. The three found an eagle nest with three eggs; Anaya propose they take all of them, but Noa remind him of the clan's law: always leave one egg. After debating that Soona and Anaya take the two eggs, Noa spotted another nest and went to investigate, leaping over a chasm using a rusted pipe to assist in climbing. He was joyed to see the nest had four eggs and as he reached to the one singing to him, the eagle that made the nest returned and attacked, knocking Noa off the nest and onto a weak ledge, leading to Noa falling along a slope. Anaya and Soona follow as Noa fell off the slope but managed to grab onto a nearby ledge and show his friends his own egg Returning to their horses on ground level, Soona noticed they are frightened, and Noa realized his blanket was missing until he heard a noise in a nearby bush. Soona used a bolo to throw a rock at the bush, which struck a strange figure that made it run. The chimps pursue the figure to a tunnel, and Noa spotted his blood soaked blanket on a branch and the figure as it ran deep inside, realizing it was an outsider. Anaya moved closer to investigate and smelled the blood, realizing the figure was not an ape and proposed it was an "Echo" (mute human). Anaya grabbed the blanket and screamed in fear with Noa and Soona as all three returned to their horses to head back home, with Noa and Soona joking about how Anaya was scared
