Early in the episode, General O'Neill describes Antarctica as "One of his least favorite continents." In the first season of Stargate SG-1, then-Colonel O'Neill and then-Captain Carter were stranded in Antarctica after a Stargate malfunction ("Solitudes"). Both were nearly killed in the incident. In the sixth season, he was infected with an alien virus in Antarctica ("Frozen"). In addition, in the seventh season finale ("Lost City 2"), after he defeats Anubis and his fleet, O'Neill entered a chamber which placed him in suspended animation, and, as shown by his double take when he passed it, the memory is not pleasant.
