S4, E17: SG-1 is called to Abydos to investigate a strange phenomenon: a whirling sandstorm that seems to whisper Dr. Daniel Jackson's name. When they confront the twisting tempest it dissolves to reveal a young boy who introduces himself as Shifu the Harsesis. Shifu is brought back to Stargate Command where he undergoes a series of tests. The tests reveal that Shifu is physically normal but it is apparent to all that the young boy is wise beyond his years. Possessing the genetic memory of the Goa'uld he undoubtedly has the potential to become a powerful weapon against the system lords. Faced with this prospect the Harsesis child sets out to teach Daniel a lesson — by imbuing him with the sought-after genetic memories and launching him on a spiritual journey. Ultimately Daniel must face a difficult challenge. Will he use his newfound knowledge to change the world for the better? Or will he allow this knowledge to change him for the worse?
