Michelle has come a long way since American Pie.
In the sequel, Jim and Michelle were just friends and he looked to her for advice in preparing for a romantic date with Nadia at the lake. His plans were in vain, though, and he ultimately realized how much he loved his band camp-attending paramour.
The third film found Jim and Michelle getting married. Despite the problems that plagued their nuptials, the two began a new life together at the end of the film.
In Reunion, Michelle and Jim are still married but have little time to spend with one another. Their romance has faltered, as their young son stands in the way of the couple's romantic bond.
