> 3. "Secrets", "Forever in a Day" (season 3 episode 10) and "Maternal Instinct" would answer these questions I think. Basically Harsesis is the offspring of 2 Goauld, it's supposed to have all their genetic memory, and is really special because of that. Yes, the boy in "Absolute Power" is Sha're/Ammonet and Apophis' son, the one who was taken away by the ascended being at the end of "Maternal Instinct". I'm almost positive it is the last episode with that kid, Oma makes future appearances though.
