Over the first two seasons of the sci-fi drama "Fringe," Peter and Olivia's connection grew from reluctant allies to a tenuous, tentative romance. When Peter lands in a parallel universe, Olivia goes after him. Her plea for him to come back with her, "because you belong with me," doesn't fix the problems of two universes, but it does lead to a kiss two years in the making!
