Well the title of this episode says it all, "Don't ask, just listen to it."

The boys travel through the gateway again, only this time one of the robots accidentally comes with them. They find themselves in a strange jungle, but have the strong feeling they are being watched.

Arguing that the robots are concerned that the boys may have been damaged by the remnants of the power system that the original inhabitants had built. The robots insist that the boys are scanned, but they do not want to be scanned.
