This alternate Jack O'Neill was almost identical to the main reality O'Neill. He married Doctor Samantha Carter in 1998. Just when they were celebrating their first year of marriage, he was called back on duty as some Goa'uld ships were present in the solar system. The two of them went in Cheyenne Mountain Complex, leaving the table. There, he died before her eyes, executed by an alternate Teal'c (SG1: "Point of View").
In the SGC infirmary, Doctor Samantha Carter is confused when she sees Colonel Jack O'Neill, who is confused as well when he sees that Major Carter has changed (the hair). Dr. Carter states that she never expected that his "Jack" would be alive in this variation.
Later, when O'Neill tells Dr. Carter that her and the alternate Major Kawalsky can stay at Stargate Command, Dr. Carter starts crying and tells her Jack's story to O'Neill. O'Neill is getting confused. Yet, he understand her husband's loss and hugs her to comfort her.
After the Asgard have delivered the alternate Earth from the Goa'uld, it's time for farewell. Major Kawalsky says it was an honor to serve with O'Neill... again. Dr. Carter seems sad as this is her second goodbyes. According to her, her Jack had "the same face, same voice... same hands." Then O'Neill asks her why she could marry such a looser. She laughs and they stare each other for a moment, then Dr. Carter kisses him. She realises that O'Neill is really not her "Jack".
