Etahy, upon meeting with SG-1, enlisted the help of Daniel Jackson to save his son and took him to see Ulysses. The duo soon managed to free both SG-1 and Aemon from the clutches of Mars, and Aemon was reunitied with his father after Etahy had phased his hand through Mars' body, supposedly killing him; what none of them knew was that Mars' symbiote had in fact survived.
