The Real World

S3, E6: Waking up in a psychiatric hospital outside of Washington D.C. Dr. Elizabeth Weir (Torri Higginson) is shocked to discover that her entire experience in Atlantis over the last two years was solely a figment of her imagination. Through the help of her psychiatrist Dr. Fletcher (Alan Ruck) she learns that a car accident that killed her fiance left her in a near catatonic state and suffering from delusional psychosis. Forced to come to terms with this new reality Weir is visited by her mother and General Jack O'Neill (Richard Dean Anderson) who assures her that he has never heard of a Stargate program let alone the lost city of Atlantis. Yet as she starts to pick up the pieces of her life she continues to have unsettling visions warning her that she must return to Atlantis. Back on Atlantis the team holds vigil for the comatose Weir who in reality has been infected by replicator nanites that are quickly taking over her body and mind. Even with the medical expertise of Dr. Carson Beckett (Paul McGillion) and the emotional support of Lt. Colonel John Sheppard (Joe Flanigan) it is ultimately up to Dr. Weir to save herself and find a way back to the real world.
