(March 2014) </Td> </Tr> <P> 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 . </P> <P> During the first season, the writers decided to keep the family's last name a mystery . In the fifth season episode "Reese Joins the Army (1)", Reese uses a fake ID by the name of "Jetson" to lie about his age . In the series finale, "Graduation", Francis' employee ID reads "Nolastname" (or "No Last Name", a joke referring to the fact that the family name was never spoken aloud). In the same episode when Malcolm was introduced to give the graduation speech, the speaker announces Malcolm's name, but microphone feedback makes his surname inaudible, even though he does appear to mouth the phrase "No last name". </P>
