Ronnie Sullivan first appears at the end of Season 1 when Dana Sue needs both of their signatures to get a loan. He wants to help but won't sign the divorce papers and works hard to regain his estranged wife.

This proves to be a challenge since she remembers that he got drunk, had a one-night stand, and cheated on her. Ronnie reestablishes himself in town and opens a carpentry business to prove he is serious about staying.

The two start marriage counseling to work on their issues and see if their relationship can be restored.
