He is the father of Samantha and Mark Carter. He also was a two-star general. He learned that he was afflicted with lymphoma, a rare form of cancer. Since there is no cure, Jacob accepted an offer from General Hammond and Samantha to become host to Selmak. He now is a liaison between the Tok'ra and Tau'ri. Since blending, he has become far wiser and less stubborn, though also more arrogant than Sam would have wanted.
