 Stargate s HQ gets a video message from Vala s most unreliable father Jacek on the planet Robak- he claims to know about the late Arkad s plans to attack and blow up Earth, even about the several cloaked, naquadah-laden cargo ships in orbit, and offers details in exchange for sanctuary. General Landry asks Dr. Lam to help him resume contact with her mother Kim, his ex. Even after the cargoes are found and blown up, Vala abhors her dad s entry. The general asks her to go easy on him, realizing that he, too, neglected his daughter because of his career, even if Jacek s neglect was just criminal. When Cam and Daniel go tell Jacek he shouldn t scam people, he tricks them into talking to Vala for him. Vala goes over just for catharsis, telling him she s through picking up the pieces of his tricks, and he certainly keeps scamming- as Daniel also finds even with Terak, a Jaffa from an escaped cargo ship, who hopes to sell the naquadah. When they are apprehended, Jacek promises to help track it and override the rigging of the cargo ship. The Jaffa wait for Jacek and Vala, intending to eliminate them now that Terak is gone, but SG-1 saves them. Since there never was an override, he cheerfully flies away alone in the cargo ship, ignoring that his treachery was anticipated, it s a decoy...
