Maternal Instinct (S03E20)

Bra'tac, accompanied by his battered Jaffa apprentice, arrives at Stargate Command pleading for medical assistance. He announces that Chulak, the home planet to himself and Teal'c, has been brutally attacked by Apophis, and he goes on to explain that it was as though Apophis was looking for something. Dr. Daniel Jackson deduces that the "something" had to be Harsesis, the child Apophis fathered with Sha're/Amaunet. This forbidden child would contain all the knowledge of the Goa'uld and, if he were to fall into the wrong hands, could be the Goa'uld's undoing. Using the combined knowledge of Bra'tac, Daniel and the available computer analysis, SG-1 decides the most likely planet on which Harsesis would take refuge is Kheb — a place from Jaffa and Goa'uld legend. Bra'tac and SG-1 travel to the planet in search of Harsesis. Realizing that Apophis could easily come to the same conclusion about Kheb, the SG-1 team knows it must hurry to find the child before Apophis does. (Metro-Goldwyn-Mayer (MGM))
