Stargate SG-1

General Hammond summons Colonel Jack O'Neill out of retirement to embark on a secret rescue mission. O'Neill confesses that he disobeyed orders to destroy the Stargate on Planet Abydos, and that scientist Daniel Jackson may still be alive. Arriving on Abydos with his team, O'Neill meets up once again with the scientist, who has discovered a giant elaborate cartouche in hieroglyphics. All signs point to the fact that this is a map of many Stargates that exist throughout the galaxy - a development that makes the dream of the SG-1 team to travel throughout the universe in time a reality.  Written by Sean Fitzgibbons

Ba'al admits not to know its secret name, while Daniel believes that that probably holds power over it; while they guess, Cam thinks of luring the dragon to blow it up, but the explosion barely impresses its digestion; Daniel makes it disappear by using Morgan LeFay's name in Ancient. They find it had guarded the frozen 'grave' of the realm's arch-magician 'Myrrdin', but Vala accidentally triggers a mechanism which revives Merlin, but also transports the whole room to another planet.

Then Adria's search for them -each time a bit quicker, one planet behind them- is visible on the Stargate dial, Merlin's corpse disappears, and they are again transported to another planet.

Daniel explains how he temporarily has Merlin's personality and knowledge in himself, and had deliberately allowed Adria to turn him into a Prior, while delaying to finish Merlin's weapon she'd wanted, meanwhile hoping to get an Ori ship for Earth's side. But time is running out, since the team took unexpectedly long to capture him. Still, the generals, Carter, and Vala are most reluctant to go along with releasing him and opening the wormhole he needs to bring the weapon through. Even the White House wants to kill him, or at best, keep him in stasis until he is reverted to his human nature by Merlin's genetic manipulation. But then his plan is wasted- unless the others can be trained to do it in his place (so only they are at risk, not the entire galaxy in case Daniel is Adria's Trojan Horse). After giving them the necessary information, Daniel suddenly frees himself while Richard Woolsey is with him and takes control of a space ship after beaming up Jack too, just after the others have undertaken their mission to Adria's lair, where Daniel, about to be genetically reverted, arrives just in time to tip the balance in favor of...

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.

Adria takes her along as she hears the team still plans to visit the address, by starship. Upon arrival, they are trapped by SG-1, which however finds itself surrounded by lord Ba'al's troops. Ba'al uses the rings to beam up Adria into an electromagnetic cage in his starship. Back on Earth, General Landry worries what damage the two might do together and wants Adria back. Daniel and Sam now show Vala she has been implanted by Galaran technology with fake recollections of her entire adventure 'til the meeting with Adria.

The team finds Ba'al's Jaffa and clones killed by symbiote poison, except one Jaffa who secretly used tretonin. The team ring-beams from the cloaked Odyssey starship into Ba'al's, shoots him and captures Adria, but back on Earth, she is found to be under the control of his symbiote. Instead of just killing the evil double, they contact the Tok'ra which send Ta'Seem to extract the symbiote and replace it with a Tok'ra one, but Ba'al manages to poison Adria, who has to be put down. Suddenly Adria wakes up, uses mind-power barricading herself in the sick bay with Vala, tells them she needs time to prepare for ascension, as Daniel guesses outside, and succeeds before the team can cut their way in by blow torch.

If not, she may have gained all their former powers, and at least one clone of Ba'al still remains...
