The Ark

S3 E16: Investigating what appears to be an abandoned space station inside a hollowed out moon Rodney McKay (David Hewlett) mistakenly brings one of it's scientists out of stasis. The scientist Henrick (Joris Jarsky) explains to the team that the base was the last effort by his people to avoid the repeated culling they've endured for generations at the hands of the Wraith. Using the Wraith stasis technology they modified a chamber to hold a large number of their people for thousands of years in the hope the wraith would find their empty planet and believe they had disappeared. But when Henrick discovers only half the number of stasis pods are present he extracts his people's leader Jamus (Kenneth Welsh) to explain. Learning that the Wraith attack had come sooner than expected Jamus sacrificed the last pod to conceal the whereabouts of the space station from the Wraith. Unable to deal with the loss of his wife and children who were in the lost pod Henrick tries to vent the space station by igniting the remaining spaceships rockets.
