Pet Project

Pet Project is the nineteenth episode of Ben 10: Alien Force.

Plot
The Forever Knights' scientist, Dr. Joseph Chadwick, sends Sir Morton to kidnap Ship from Julie so that the Forever Knights can use him to mass-produce a fleet of interstellar spacecraft. They then plan to use said fleet to attack the homeworld of the alien dragon that escaped them. Joined by Julie, who has been taking care of Ship, Ben, Gwen and Kevin mount a raid on the Forever Knights' stronghold to rescue him. Though Chadwick is using a control device to make Ship obey him, Julie is able to convince Ship to resist. The Forever Knights' stronghold is destroyed, and the group now has access to a spaceship since Ship can transform into the vehicle the Forever Knights had hoped to mass-produce. The episode ends with Ship reuniting with Julie.

Trivia

 * It has been frequent for a character to point out Kevin as Gwen's boyfriend (e.g. Frank in What Are Little Girls Made Of?, Helen in Plumbers' Helpers and Sir Morton in this episode, when he said, "Relax girl. It's not your boyfriend I'm after."
 * This is the 1st time Ben goes Jetray in his room, the 2nd in Vengeance of Vilgax: Part 1, the 3rd in Fused and the 4th in The Mother of All Vreedles.
 * In this episode, it is noticed that Ben and Julie seem to share many similar traits in nature and likings, like Julie getting equally upset with Ben when he was upset with her and coincidently watching the same serial, Brainstealers From Space.
 * Ship is able to transform into any machine wherever he is. However, when Ben transformed into Upgrade, he could only take control of machinery by covering it with his body. He could never completely transform into the object. This is due to Ben's incomplete transformation into the fully mechanical Galvanic Mechamorph.
 * In Pier Pressure, in order for Ship to transform into a machine or vehicle, he had to enter it first (e.g. truck, go-cart, etc.). In this episode, he automatically turns into a massive spaceship.
