Lowe, 45, plays Robert McCallister, a United States Senator, married to Flockhart’s Kitty Walker.
The pair hit the rocks last season after they adopted a baby, Robert had a heart attack and Kitty almost had an affair.
Season 3 ended with the two separating but Lowe says things will change in the new season.
“Last season was the study of a disintegration of a marriage and we begin this year worlds apart,” he said.
Lowe says a tragedy will strike early on that ultimately help bring the two together.
“It’s going to be what they needed to try to put the pieces back together … and pretty romantic,” he said.
The fourth season of ‘Brothers & Sisters’ premieres Sunday, 10 p.m. EDT on ABC.
