Having regained control of the X-303, the SG-1 team finds itself in an unknown part of space. Rescue comes in the form of the Asgard, specifically Thor, who needs their help. The Asgard home world has been overrun by the Replicators and they require SG-1's help as well as the relatively low tech X-303. The Asgard had set a trap for the Replicators and hoped to use a time dilation device that would give them the time they need to find a way to defeat them. The problem is that the Replicators have turned off the device and the Asgard want SG-1 to go in and activate it. They accept the assignment but to meet their objective, O'Neill will face a moral dilemma. Written by garykmcd

Saving humanity ?
11 June 2010 | by (France) – See all my reviews

Although the episode picks up right where "Prometheus" ended, there is little connection between both eps. Instead of Goa'ulds and NID traitors, we're now dealing with the Asgaard's favorite toy robots, the Replicators. There is a rather lengthy bit of catching-up as Thor explains the current situation, then the real action starts. It's rather fun to see how blasé the SGC crew have become with the Asgaard's rather cavalier interferences. Saving galaxies is now something they do at lunchtime --if they don't have an appointment to kick some Goa'uld butt first.

Anyway, the second part of the episode is much more disturbing as we discover what the Replicators have been up to. It also raises a lot of fascinating questions about what humanity is... but regrettably, once again one episode is much too short to properly deal with them. The interesting point is that even though SG-1 obviously get away with it, they don't exactly do so with honours. (Daniel would never have agreed.) And even though O'Neill has repeatedly denied that robots might be treated as humans, he clearly feels bad at having "done the right thing".

Now I hope that there will be some follow-up on that story, as it concludes a really huge arc and could have major repercussions on both the series and its ethical stance. But maybe that's too much to ask.
