At a Silurian zoological research station, Velk is unimpressed by Nagara and Guruz's display of the captive apes and of his attempts to force pre-human apes to learn and display intelligence. He is more concerned with a call to all Silurians to take to the shelters to avoid the predicted collision with of Earth and its planetary neighbour.
Kin, leader of the apes, strangles Guruz in response to another beating. Nagura returns to set the Apes free. Believing the Apes to be thanking him for the discipline he offered them, he accepts a woven headband like Kin's. Only when the headband is in place does he realises his third eye is blocked by a stone at the front and he is powerless. The apes exact their revenge for their brutal captivity.
