Originally there were four brothers (although Malcolm 's oldest brother attended a military school away from home, so Malcolm was still the middle sibling left at home). A fifth son was introduced in the show 's fourth season, a boy named Jamie. The boys are, from eldest to youngest: Francis, Reese, Malcolm, Dewey, and Jamie. In the final episode, Lois discovered she was pregnant with a sixth child. In the third season, Francis travels home (to celebrate his father 's birthday) with an Alaskan girl named Piama, and reveals that they are married.
