“Pegasus” sends SG-1 to the lost city of Atlantis in the Stargate franchise’s first major crossover episode. “Insiders” brings back a major villain from SG-1‘s past, revisiting a key storyline from last season.
Watch out for significant spoilers below! Here’s how SCI FI describes these episodes:
THE PEGASUS PROJECT
Guest Stars: Joe Flanigan, Torri Higginson, David Hewlett
The SG-1 team travels to Atlantis to attempt to establish a stable wormhole to the Ori Supergate, which will prevent the Ori from sending more ships to Earth’s galaxy. In order to do so, Carter (Amanda Tapping) and McKay (David Hewlett) must detonate precisely calibrated nuclear warheads to cause a wormhole to “jump” from a nearby Spacegate to the Supergate, without destroying their ship, the Odyssey, in the process.
Meanwhile, Daniel (Michael Shanks) and Vala (Claudia Black) take advantage of their time at Atlantis to research the Atlantis database for clues to the location of Merlin’s weapon. During their research, they are met by Morgan Le Fay, an ascended Ancient posing as the Lantian holographic interface, who gives them the names of two planets where the device may be located. But can she be trusted?
Weir (Torri Higginson) detects a Wraith ship headed towards the Odyssey, and is unable to relay the message due to the interference of the nearby black hole. And the Odyssey detects an Ori ship headed toward the Supergate. Will the team be able to complete their mission before they are attacked?
INSIDERS
Guest Star: Cliff Simon
As SG-1 continues to piece together clues to the whereabouts of the elusive Ancient weapon that could defeat the Ori, an alien vessel streaks into Earth’s atmosphere towards Stargate Command (S.G.C.). When the vessel does not respond to hails, it is shot down and crash lands. To everyone’s surprise, the pilot is none other than Baal (Cliff Simon).
Baal informs SG-1 that his clones, which he had created to assist him, are now turning against him, and he is seeking SG-1’s help in tracking them down and obliterating them. In exchange, he promises to assist SG-1 by giving them the key to finding the planet on which the Ancient weapon is located.
Realizing that Baal’s clones might turn over the location of the weapon to the Ori, the team sets to work capturing the clones and bringing them back to the S.G.C. Soon, there are nearly 20 Baal clones in isolation at the S.G.C., all claiming to be the real Baal. Before the team members are able to elicit any useful information from the clones, they escape — turning Stargate Command into a battlefield.
“The Pegasus Project” will air on SCI FI in the United States on July 28, followed by “Insiders” on August 4. Learn more about these and other upcoming episodes in GateWorld’s Season Ten episode guide!
