Season 7
133 :07x01 - Fallen (1) (Jun/13/2003)
.Jonas Quinn finds what he thinks to be the information needed to find the Lost City of the Ancients. After letting General Hammond know this, SG-1 heads off to the planet in question, where they find some ruins. While there, they meet a group of travelers who have taken up refuge. This also leads to the discovery that Daniel Jackson has returned to corporeal form, but apparently with no memories whatsoever of his past.

After a bit of convincing from Jack and Sam, Daniel decides to return with them to Earth to try to recover his past memories. While Daniel is doing this, an extensive search is made of the ruins, but they come up empty handed.

Slowly but surely, Daniel begins to remember parts of his past life, and rejoins SG-1. Then he finds that he is able to read a Ancient tablet that was found, and realizes that the planet SG-1 is searching for is in fact the wrong planet.

With Anubis still becoming more and more powerful, SG-1 and the Tok'ra devise a plan to lure him to this planet with a fake tablet so that they can take out his new super weapon. Teal'c then heads off to the system lord Yu, to forge an alliance so the full force of the combined system Lord’s fleet can attack Anubis, once his super weapon is destroyed.

This leads to Daniel and Jonas to ring up to Anubis’ ship, to get the coordinates for the shield generator, while O'Neill and Carter fly a F-302 in close to take out a ventilation port to destroy the weapon. Unfortunately, a growingly senile Lord Yu orders his fleet to a different system, so there is nobody around to attack Anubis once the weapon is gone.

After this happens, Jonas is captured and Daniel manages to climb into an air vent, but both are still on Anubis' ship as it escapes into hyperspace.
