Monkey - Season 2 Episode 26 At the Top of the Mountain

Tripitaka has an ominous dream that his mother is dying, and becomes very preoccupied the next day. Concerned about his master, Monkey cloud-flies back to China, and finds Tripitaka's mother, Wing-Chow, infected with a deadly plague. Just before dying, she tells Monkey that her son, original name Hsüan Tsang, must continue his journey to India. Monkey returns and impersonates Wing-Chow, to pretend she's alive, fearing that Tripitaka would stop his journey and return to China if he knew the truth.
