Malcolm argued with his mother for years about not being matched up with the random women she tried to set him up with. After everything that happened with Martin, Jessica had enough and since Dani I wanted nothing to do with Malcolm after seeing him stab his father, Jessica married him off. Malcolm did everything possible he could to avoid it. Finally Malcolm agreed to sign the marriage paperwork if he didn't actually have to have the full-on wedding. However, he never read the fine print where he signed that he would live with his bride. His mother told him over Sunday dinner that his bride was moving in and Malcolm practically ran back home to confront his new wife.
