Rejuvination

A flashback reveals how Picard drained people's magic essence in the past in order to rejuvenate himself. Back in the present Picard does the same thing in order to get younger. Data informs him that with a material called Serilium he could drain the life force from millions of people at a time. Scotty tells them that Captain Sulu has this material. The Enterprise attacks Sulu's ship to steal the material. Picard then drains the life of 20 million people on a planet, rejuvenating himself to a pre-pubescent age. He then dresses like a girl and goes back to the Academy to be Wesley's roommate.
