Storyline

SG-1 returns early from a mission only to realize that they and Gen. Landry aren't on the same page as far as the the mission they've just completed is concerned. The confusion is quickly resolved when the "real" SG-1 returns at the correct time. Dr. Lam examines them all and concludes that they are identical and thinks they might be clones. Sam however thinks they may have come from a parallel universe as the result of the black hole they created when they destroyed the Ori beachhead. As more SG-1 teams arrive from other alternate universes, one of them includes Dr. Fraiser and another includes the Tok'ra Martouf. It's left to Sam and Martouf to find a way to send them all home.

Trivia

Commonly thought of a plot hole, but evidence shows this is not the case.

In Stargate SG-1: Point of View (1999), when duplicates of Samantha Carter and Charles Kawalsky arrive through the Quantum Mirror, it was stated that alternate Samantha was suffering from "Entropic Cascade failure on the cellular level" as a result of both Samantha Carters co-existing in the same reality. This was explained as being a side-effect of travel through the Quantum Mirror.

In this story, there was no travel through the Quantum Mirror, but the cause of the confluence of realities was explained as... "... a supernova or Gamma Ray burst discharging at the exact millisecond that wormhole passed through that singularity...". In the Stargate story-line, this is the reason all 16 stranded SG-1 teams were able to co-exist with each other and with the original team of this reality. See more »

Goofs

It should have been immediately noticed that the first SG-1 team coming home through the gate had black uniforms instead of the normal green ones, and that something was definitely amiss. See more »

Quotes

Hank Landry: We've had teams gate in from locations on the other side of that black hole in our universe. Why weren't they affected?
Cameron Mitchell: I have one more stupid question.
[Landry turns around]
Cameron Mitchell: Sorry, yours was fine. Mine is stupid.

Love Stargate!! but this was just very bad writing
6 July 2015 | by dimbostSee all my reviews

Hey guys, you know that i usually review movies, or series as a whole, but being a huge Stargate fan and re watching all of it back to back, just had to review this really poorly and "Fun" but stupid episode of SG1 Season 9 episode 13. So why do i love and hate this episode? Well i love it, because we got to see many variations of SG1, although they should have mixed it up more and included Jack on one of the teams, also could've shown more interaction that each one has with their different selves. The reason i hated it, and was surprised at how badly the episode was written was because in season 3 episode 6 "Point of View" Stargate world clearly establishes a law, that no two person can exist in one universe! Carter started to suffer entropic cascade failure at the cellular level because their were two of her in one reality. However in this episode there is stated that there are 18 Different SG1 teams at Stargate command, and by multi verse theory law, that universe should destroy it self, or have all of the duplicates die off. But we do not see that, and there is no mention of any one starting to suffer from being in one universe.

I love Stargate, but i did feel that this episode was poorly written and could have been avoided.
