Alternate realities and alternate timelines

 * In another alternate reality, Jack O'Neill had been married to Dr. Samantha Carter for a year by 1999. He died in the Goa'uld invasion of Earth, having been killed by Teal'c, the First Prime of Apophis, in front of his master as well as Sam. His death had a huge emotional impact on his wife. It seems that he was very similar to his counterpart in our reality. It appears that he also frequently used the phrase "for crying out loud" and would not "have a clue" what to tell a woman in the middle of an emotional crisis. The Jack of our reality asked her how she could marry "such a loser." Major Charles Kawalsky considered Jack his best friend. Consequently, he reacted angrily upon seeing the Teal'c of our reality at Stargate Command, though he eventually came to trust him.
