Aris is still poorly; the baby woolly monkey finally gets a name; and the alpha male chimps exert their authority. But could there be a coup brewing?

The Chilean capuchins finally arrive in the UK, and there is bad news in the orang-utan house. Something has gone seriously wrong for Aris since his knee operation.

Orang-utan Aris needs surgery as his knee injury is worse than expected. Chimp Patricia finally relaxes in the company of alpha male, Hananya. And chimpanzee Seamus is in for a shock when he meets big male, Paco.
