Daniel is discovered naked and without memory on the planet Vis Uban in the season 7 opener "Fallen". Daniel rejoins SG-1 full-time one episode later, and Jonas returns to his people. Daniel spends much of season 7 trying to tap into his Ascended memories of his time of Ascension and to find the Lost City of the Ancients. This leads to the discovery of the Ancient Outpost at Antarctica in the season 7 finale "Lost City", contributing to the spin-off "Stargate Atlantis". In season 8's "Prometheus Unbound", Daniel meets Vala Mal Doran, who seizes the "Prometheus" with him on board. Although Daniel evades her sexual advances and thwarts her plans, she escapes. After Daniel's death at the hands of RepliCarter in "Reckoning (Part 2)", Oma Desala provides a path for Daniel to ascend in "Threads", but Daniel is descended back to Earth naked to live on as a human, this time with full memory of what just happened to him.
