This is episode 2 of series 10 and it's off to a good start. Episode one has the job of trying to bridge the gap from the previous series; it has the job of reminding the viewers where we are in the story-history and also kick off the story lines for the upcoming series. So episode two is where we get the first full story.
There are two story threads. Vala has to prove to Major Landry that she can be a team player and has to pass a psychological test. Mitchell, Jackson, Carter and Teal'c follow a lead to an empty village to go through it's library for clues to three places where a weapon may be found that can defeat the Ori. Unfortunately, what they find is a sleeping sickness that infects them all. They can't go back while infected; they can't stay or the sickness will kill them... There are lots of good moments in this episode. Claudia Black (as Vala) is just a wonder to watch in a role that she's obviously having fun with. I sincerely hope that she's going to be a permanent addition to SG1. The second Psycho-babble question she looks up in order to 'cram' for the 'test' is from Blade Runner - 'You see a turtle upside down in the backing sun... Why aren't you helping it?'. Her answer: 'Because you are a turtle too'. Magic! Mitchell's 'Are they the Knights who say "Ni"?' is from Monty Python's Holy Grail (or 'Spamalot'). With Arthur featuring highly in series 10 this surely is the start of a whole series of Monty Python and the Holy Grail quotes!
Morpheus is, of course, the god of sleep.
