Stargate Atlantis 408 (The Seer)

Sigh... Teyla is in no danger! It turns out that she's pregnant. I think it's something they decided to work into the story because the actress, Rachel Luttrell is actually pregnant. But who's the father? That'll probably be answered in a future episode.

Back to the main plot of The Seer... this episode was another SG-1 concept recycled for Atlantis. The team comes across a man that can foresee glimpses of the future. So the Atlantis crew started to over-prepare for a wraith and replicator attack, in an attempt to change their fate. All of the events happen anyway, but the glimpses of the future ended up happening in different context. This idea was first seen in Prophesy, an episode in season 6 of Stargate SG-1 when Jonas Quinn gains the ability to see "clips" of the future, but not the events that lead to the visions.
