Brian turns down a chance to see "Disney on Ice" with Jillian, so she decides to give his ticket to Peter. Brian claims to be relieved, telling Lois he has been feeling smothered lately and needs to focus on his writing. After Peter and Jillian spend the entire day together and greatly enjoy each other's company, Peter convinces Jillian to either force Brian to let her move in with him or leave him. Brian is angry at Peter for doing this, as he feels it is too soon for them to have a committed relationship, but after Lois warns him that he is not being fair on Jillian, he agrees to get an apartment with her. Much to his surprise, Brian has a good time living with Jillian, but he comes to the realization that there is no way he can pay the rent by himself and he decides to allow Stewie to move in with them, who now makes money with his own paper route.
