Synopsis:
Superboy leaves Earth to live with two people claiming to be his real parents, Jor-El and Lara. When word of this reaches death row convict Duke Mason, he is angry. Mason has just deciphered a code which revealed Superboy's secret identity. With Superboy gone from Earth, Mason is unable to take revenge and dies in the electric chair.

Superboy witnesses the execution with his telescopic vision. He then decides that he can safely return to Earth. His parents were really actors hired by Superboy. The hoax was created in order to stall until Mason was executed.

Back on Earth, the Kents find a note left by Superboy revealing his plan. The note had been lost, so they were heartbroken over Superboy's decision to leave. They nearly reveal their son's secret to the people of Smallville, but find the note in time. Jonathan then uses a Clark Kent robot to protect his son's secret, until the real Superboy returns.
