It's show and tell for Vegeta as he demonstrates just how much difference a year of hard work can make! Watching from the sidelines, Trunks recalls the intense time he spent training with his father, and up in the Hyperbolic Time Chamber, the pressure falls on Gohan as he tries to become a Super Saiyan. That's no easy task, especially for a kid!
