"Ripple Effect" is an episode from Season 9 of the science fiction television series Stargate SG-1.
[edit] Plot
After an unscheduled Stargate activation, the first of many SG-1 teams originating from many parallel universes arrive at the SGC. While more and more alternate SG-1 teams arrive (each conveniently clothed in a different color uniform) Col. Carter and Dr. Lee, with help from alternate (brown) versions of Carter and Martouf (who never died in his world), try to find a way to bring those teams back to their own reality. When they fail to find a solution, SG-1, with help of the Asgard, decide to stop the black hole which is responsible from diverting the teams out of their realities. The native SG-1 (in green) and the first alternate SG-1 team which came through the gate (in black) use the Prometheus to reach the black hole. However, the alternate team take over the ship and heads to Atlantis to steal the ZPM. The black alternate team explain that they need the ZPM to power their defenses in their reality, and planned this entire situation to steal it from this reality. The native green SG-1 manage to retake command of the Prometheus by impersonation and turning an attempted trap back on their counterparts, and return to Earth, where they use information from the alternate team to send all the parallel universe teams home.
[edit] Notes
- This episode features Dr. Fraiser being alive and part of another reality's SG-1.
- Thor is unavailable for help because he is on an unspecified mission in another galaxy. A new Asgard character is introduced to assist, Kvasir, whose attitude is best described as pompous, which causes Daniel Jackson to muse "I miss Thor" (possibly an injoke, as Michael Shanks provides the voice of Thor).
- Carter learns that she had a relationship with Martouf in another reality but, due to the long-distance factor, among other things, it did not work out there either.
- Carter is married and on maternity leave in another reality.
- Selmak is alive in one of the alternate realities.
- The first three teams to arrive all wear different uniforms - first black, then green, then brown camouflage - yet the first team to arrive is mistaken for the real team that is wearing green.
- The first Mitchell to go through the gate (in the black uniform) leaves with a cryptic remark to his counterpart in our reality; "when the time comes, cut the green one." According to Joseph Mallozzi in his blog, the meaning of this remark will not be revealed in the series but might come up in the Stargate SG-1 sequels, Stargate: The Ark of Truth and Stargate: Continuum.
- While on the Prometheus, Mitchell makes a reference to the Star Trek episode "Mirror, Mirror" where the mirror Spock had a beard. "You don't have beards, so you're not from the evil twin universe."
- An alternate SG-1, composed of several un-named members, appears to be wearing the Atoniek armbands ("Upgrades").
- It is hypothesized by Dr. Lee that the close proximity of the realities explains how the alternate SG-1 teams don't suffer from entropic cascade failure as an alternate Carter did in another episode dealing with alternate realities, "Point of View".
- At one point in the episode, when the original Col. Carter is talking to Dr. Lee, an alternate Carter is seen eating green Jell-O in the background while the original Carter always eats blue.
- This episode was overly long, so many scenes had to be edited and even cut for time. Joseph Mallozzi posted script sections of all cut scenes in his producer installment on Gateworld.
