Remnants

"Remnants" is the fifteenth episode of the fifth season of Stargate Atlantis.

Summary
John Sheppard has been abducted. He regains consciousness, finding himself in a forest on the mainland of Atlantis's new home planet, to which the city was relocated a year and a half earlier. His hands and feet are bound, and Sheppard shuffles himself toward a sharp rock to try and free himself from his bonds.

Back in the city, Richard Woolsey encounters a new member of the expedition in a transporter chamber. She introduces herself as Dr. Vanessa Conrad, a scientist who has recently arrived on the Apollo. Woolsey is immediately smitten, and breaks the ice by telling her about Atlantis's regular social activities -- Yahtzee tournaments, movie screenings, organized sports, and more.

Soon, the two are on a first name basis. But there is certainly more to this woman than meets the eye.

Colonel Sheppard manages to free himself, and returns cautiously to his Puddle Jumper. He soon discovers who it is who tied him up: Acastus Kolya, the former Genii commander and torture master whom he shot dead two years ago.

In Atlantis, Woolsey, McKay, and the rest of the team are about to make a shocking discovery -- a discovery about about an ancient race, Atlantis's fellow residents on this new planet, and what they need to survive.
