Out of Mind

S2, E22: Awakening from what seems like cryogenic suspension O'Neill finds himself in a futuristic version of the SGC surrounded by unfamiliar faces. He is told by doctors he has been frozen for 79 years and the rest of the SG-1 team perished long ago. The doctors hook O'Neill to a device which turns his memories into holographs then question him for information about races able to defeat the Goa'uld. The doctors claim they need all the help they can get in their current war against the Goa'ulds. When O'Neill overhears the doctors speaking in Goa'uld voices he realizes he maybe part of an elaborate set up. He escapes and discovers the SGC is actually a replica built inside a Goa'uld stronghold and that in nearby rooms Daniel and Carter are undergoing similar treatments. Attempting to escape the three are blocked by Hathor who enraged by their refusal prepares to implant one of them with a larvae.
