Character mistake: It is mentioned the previous solar flare was 15000 years ago, and Shepard says that the ancients were in the middle of a war with the wraiths, but as stated in previous episodes the war lasted 200 years and ended 10000 years ago. (00:31:30 - 00:38:10)

Dr. Rodney McKay: All I know is that she's not who she's pretending to be.

Dr. Rodney McKay: What, I'm not allowed to have intuition?
Elizabeth Weir, Ph. D.: You? No.

Trivia: Richard Kind who plays Lucius Lavin in this episode also appears as Gary Meyers in the original Stargate movie.
Question: Why can't they use every last iota of energy they've got and dial earth and ask them to send them any ZPM's that they could find?
Answer: Because even all 4 Naquadah generators (one was destroyed) together is only enough to dial Earth for approximately 1.2 seconds (As seen in the episode "Letter from Pegasus"). Further, if Earth had found a ZPM, they would dial Atlantis and let them know. After all, the SGC has no other use for a ZPM than to dial Atlantis.
