Stargate Command is stunned to discover a strange civilization living on an inhospitable planet when they send a probe through. There is a society living beneath a dome on an otherwise completely unwelcoming world.

So of course, the team investigates.

Revisions was written by Joseph Mallozzi and Paul Mullie and first aired on 11 July, 2003.

The population are all connected together via an implant on their head, a neural link. They are able to access all information in their libraries instantly. But there is something odd going on here. One of the citizens vanished overnight, and no one remembers her existing except SG-1.

O’Neill (Richard Dean Anderson), Carter (Amanda Tapping), Daniel (Michael Shanks) and Teal’c (Christopher Judge) become suspicious of the link, the computer running it, and the society’s tiny existence.

As people and locations change around them, Carter attempts to understand what the computer system is doing to the people through the link. The dome they live under is shrinking as the computer loses power, and it is re-writing the memories of those within to forget they existed.

Can SG-1 fix the computer? Or save the society?

I really liked this episode once it kicked into high gear. Once SG-1 figures out what is going on, it’s fun to see how they work to save everyone. It’s smart, fun, and I love the interactions of the team. And hey, there’s Christopher Heyerdahl who pops up in lots of genre work.

I like the location, and I love the fact that the series is seven seasons in, and is still incredibly entertaining.

Lifeboat lets Michael Shanks shine. SG-1 arrives on a planet where they discover a crashed ship filled with bodies being kept in stasis. When the entire team is rendered unconscious, Daniel awakes with several of the personalities of the frozen crew download into his mind.

Written by one of the showrunners, Brad Wright, this episode was first broadcast on 18 July, 2003. It was directed by Peter DeLuise, who has a cameo as one of the bodies in a cryogenic chamber.

The team is recovered and taken to the SGC infirmary, where Fraiser (Teryl Rothery) tries to figure out what is going on. Daniel is being seen over, but he is increasingly erratic as personalities shift within him – something that Shanks was given an acting award for.

As Fraiser and Daniel’s inhabitants make some headway, one of them reveals that the only way that could have happened is if the original host body was dead. So what will happen to the souls inhabiting Daniel?

But is everyone on the ship really dead? Carter and Teal’c go back to investigate, while O’Neill watches over Daniel’s sessions.

Carter discovers a couple of survivors, who also has a number of personalities in his head, and between them, they may figure out a way to save them all, or perhaps let them finally rest in peace.

A solid episode, and Shanks does a wonderful job.
