Jacek was absent for the first three years of Vala's life, running scams out of the Nylus sector. Jacek would occasionally return home to lay low and hide from people he had scammed, always bringing back a trinket for Vala. In 2007 Jacek contacted Stargate Command and traded the location of several of Arkad's Naquadah-heavy Cargo ships destined to attack Earth in exchange for sanctuary on Earth. Jacek spent three weeks on Earth, constantly trying to contact his daughter, running a charity phone scam, writing a diet book and marketing glitter shavings as "Stardust".
Jacek met with a Jaffa contact on Earth hoping to sell the Naquadah he had in his possession but was caught out, having to help SG-1 locate this ship. Jacek, under the guise of disabling the ships self-destruct, left Earth with the Naquadah. However SG-1 had anticipated this and had a decoy Cargo ship filled with Lead bars in place of the Naquadah. Jacek attempted to sell the "Naquadah" but when he discovered the switch, instead sold the packing peanuts in the containers as "Jibbaran virility enhancers". (SG1: "Family Ties")
