Stargate Command readies for an unscheduled incoming wormhole when a sudden unusual energy spike surprises everyone. The IDC confirms that SG-1 is returning early from a mission, and they step out of the stargate in their black off-world uniforms. During their debriefing, they mention several details that strike Landry as anomalous. Before they can resolve the discrepancy, the stargate activates again – and the SGC once again receives SG-1’s IDC, this time on schedule. Landry orders the iris opened, and SG-1 emerges from the wormhole wearing green off-world uniforms.
Genetic tests confirm that both teams are the real SG-1, but the green team’s mission and memories sync up with the history experienced by Landry and the rest of the SGC. The green team interviews the members of the black team to try and figure out what is going on. Landry suspects that Baal’s cloning technology may be at work, but Green Carter argues that an anomaly may have caused the wormhole to jump between parallel realities. When additional SG-1s begin contacting SGC asking to be let home, the hypothesis is pretty much confirmed. Green Carter and Black Carter theorize that a wormhole that interacted with the black hole created by the Ori’s attempt to create a super-gate to the Milky Way may have established the anomaly. Now those alternate realities that are relatively close to Green SG-1’s are being funneled there. Landry orders all gate travel suspended, except for emergencies – which still allows over a dozen alternate SG-1s to reach this reality.
One of those teams, whose members include Martouf and Dr. Fraiser, is searching for a cure for the Ori plague. But even a team of eighteen Samantha Carters can’t figure out a way to reverse the anomaly and return the stranded teams to their own realities, so Landry reluctantly concludes that in the name of protecting this reality, the anomaly must be eliminated even if it strands the other teams. Kvasir of the Asgard offers assistance in devising a plan to do so, but Landry is not the only one who is willing to take whatever steps are necessary to defend the home reality – whichever reality that is.

Notes: The Ori created the black hole in this season’s Beachhead and the SGC found a cure for the Ori plague in The Fourth Horseman, Part 2. The Carters referred to the black-hole-created time dilation effect that occurred in season 2’s A Matter of Time and the time travel effect from that season’s 1969. Black Mitchell referred to the Goa’uld plot to trick SG-1 into thinking they had returned to a far-future SGC in season 2’s Out of Mind and to the Atlantis expedition’s experience in the Stargate Atlantis season 1 episode Home. The home-reality’s Dr. Fraiser was killed in season seven’s Heroes, Part 2. The home-reality’s Martouf died in season 4’s Divide and Conquer.
