5. Brutal Youth

Complete story — includes the ending

Lois and Clark return from their honeymoon when an old man shows up at the Daily Planet asking for Jimmy. Before he tells him what he wants, the man drops dead and despite looking over seventy, his identity says that he is in his twenties. Lois and Clark go to Dr. Klein (Kenneth Kimmins) to find out what happened to the man while a prisoner named Conner Shenk ( John D'Aquino (young) and Sandy Ward (old) ) escapes from prison. Lois finds out that Superman's aging process differs from human people in that it actually stabilises and slows, which means that when she is old, Clark will still be very young, and this news upsets her greatly. In the meantime, Jimmy tries to investigate on his own and gets captured by a scientist named Vita Duetsen ( Caroline McWilliams ) who is revealed to be behind Shenk's escape and the mystery with the young/old people. Lois and Clark discover her and Superman uses her machine to make Jimmy young again by giving him some of his life years so Jimmy will not die. Duetsen is arrested and Shenk will return to normal soon since he was transformed into a baby and head back to prison. Clark purchases Duetsen's house as Lois says she likes it and he likes it as it has a secret compartment which is difficult to find in that style of building and told her that he gave up a few years of his life to save Jimmy. Note: An artificially-aged Jimmy is portrayed by Jack Larson, who portrayed Jimmy on the Adventures of Superman television series.
