In " New Kidney in Town ", he dognaps Brian to prevent the pet from giving the dying Peter his kidneys, and tells him, "I won't let you give your life for the fat man," in which Brian responds, "You can live without a dog but you can't live without a father." Stewie cries and embraces Brian, who gets covered with mucus dripping from the baby's nose. In " Yug Ylimaf ", Brian (inadvertently) names Stewie. This was after Brian accidentally reverses the flow of time and Stewie is unborn. After correcting his mistake, Brian rushes to the hospital just in time to see Stewie's rebirth. As he arrives he asks "Where's Stewie?", confusing the family. The family then decides to stick with the name Brian mentioned, therefore re-giving Stewie his name.
