Forever in a Day

S3, E10: During a rescue of captured Abydonians including his father-in-law Kasuf Dr. Daniel Jackson sees his long-lost wife Sha're watching the activity from a nearby tent. He follows her inside where Sha're — who is actually the Goa'uld Amaunet — takes Daniel in the grip of a Goa'uld ribbon device. Teal'c enters the tent with his staff weapon as Daniel falls unconscious. Daniel awakens in the Stargate Command infirmary where Teal'c sadly admits he was forced to kill Sha're to save Daniel's life. Daniel refuses to believe this until he is shown Sha're's body. Distraught over his wife's death and angry at Teal'c for causing it Daniel pulls away from his friends and resigns from the Stargate program. When Sha're starts appearing to him in vivid dreams Daniel must overcome his grief if he is to understand her desperate message.
