In the season premiere, it's the first day of fourth grade for Ritchie. When Christine and the other moms meet the class' disarmingly handsome new teacher, Daniel Harris (recurring guest star Blair Underwood), they decide to schedule a few parent-teacher conferences immediately. Meanwhile, no longer dating New Christine, Richard stays with Christine while he builds a new laundry room for her. But problems arise when Ritchie misinterprets the comfortable arrangement and believes his parents have gotten back together. Christine scrambles to find a way to explain that she could never reunite with Richard--or could she?
