Smallville IV (20/22)

Clark and Lana discover an abandoned baby in a cornfield and take him back to the Kent farm. But when the newborn ages to a 7-year-old in a matter of days, Clark and Lana frantically search for a cure before the rapid-aging disease kills him. Meanwhile, Genevieve (recurring guest star JANE SEYMOUR) orders Lionel to kill Lana or Genevieve will send him back to prison.
