They\'ve been desperately searching for her, but they risk their lives every time they enter a world. Xander has traveled back to visit Uncle Jesse as a boy, but that turns out to be the last place Xander wants to be. Jesse tells him David died. But Xander\'s not about to let that happen--even if it already did. It doesn\'t matter how many worlds he has to go to or what it takes, he is going to find a way to change the future.
