Moebius (Stargate SG-1)
"Moebius" is about the discovery of a Zero Point Module (ZPM) by SG-1, the only problem is that it was taken by Ra after the Earth revolt more than five thousand years ago.
The team decides to travel back in time to get the ZPM and leave without changing history (based on the fact that Ra and company were most likely unaware of the ZPM's purpose), but they are unable to travel back to present time so they record a video for the United States government to find.
Samantha "Sam" Carter reveals the existence of the Daedalus: a new Earth-built battlecruiser which is capable of reaching the Pegasus Galaxy and is larger and more advanced than the Prometheus.
The video contains a recording of the original SG-1, explaining who they are and what they were doing, as well as a number of things that are true in their timeline, such as recent political events, Presidents and personal details.
Their plan is that if things have changed in the future, then SG-1's alternative selves will travel back in time and fix the past.
and use the Stargate to pass from Chulak to Ancient Egypt where the original versions of SG-1 were stranded and where Ra is still alive and ruling.
The rebellion ultimately succeeds, but not before alternate Carter and alternate-O'Neill show their feelings for each other with a kiss, uncertain if they will survive.
[2] They ultimately agreed on about ten initial episodes, two of which should make a two-hour premiere to address left-open issues of the season seven finale.
[3] O'Neill's last line in "Moebius", "Close enough" is a homage to The Simpsons episode "Treehouse of Horror V" that involves Homer Simpson time traveling and unintentionally making numerous changes to history; upon returning to a timeline where his family has snake tongues but everything else is otherwise normal, he says "eh, close enough".
Alternatively, this line could be a reference to Ray Bradbury's A Sound of Thunder, the original science fiction story that involved changes in a timeline caused by stepping on an insect, which influenced the Simpsons episode.)
[4] "Moebius" was supposed to be the Stargate SG-1 series finale (like the two previous season finales), so many actors reprised their roles from past episodes: Don S. Davis as George Hammond, Peter Williams as Apophis, Colin Cunningham as Major Davis, and Jay Acovone as Charles Kawalsky.
This is the last episode to feature Richard Dean Anderson character Brigadier General Jonathan "Jack" O'Neill as a main cast member of Stargate SG-1.
[6] Christine Mooney won a Leo Award in the category "Dramatic Series - Best Costume Design" for "Moebius" (Part 2).
