How to Watch How to Download

Trust is a fragile thing, especially when built on a history of villainy. In Ben 10: Alien Force Season 1 Episode 4, "Kevin's Big Score," the newly established camaraderie of the group faces its first major trial when old habits resurface and personal agendas collide, exposing the dark underbelly of the alien black market.

Just as Ben and Gwen are beginning to genuinely rely on their former enemy, Kevin Levin abruptly betrays them by stealing Grandpa Max's beloved motorhome, the Rustbucket. Driven by a desperate need for rare alien technology, Kevin's rogue mission quickly spirals out of control, forcing the team to learn what it truly takes to redeem a flawed ally.

“Old habits die hard, but true loyalty is forged when a team stands by you even when you hit rock bottom.”

Episode Summary

The episode starts with a sudden betrayal: Kevin steals the Rustbucket to trade it for highly confidential alien tracking tech. His transaction partner is Argit, a shifty, quill-shooting space con artist. Instead of an honest trade, Argit double-crosses Kevin, steals the Rustbucket for himself, and leaves Kevin stranded.

Ben and Gwen track Kevin down, furious but determined to fix the mess. Realizing he needs their help, Kevin confesses he was trying to acquire a special Holo-Viewer containing a message from Grandpa Max. The trail leads the trio directly to the subterranean lair of Vulkanus, a bitter old enemy of Ben's who is running an illegal mining operation using forced labor.

Vulkanus captures Kevin and forces him to absorb a rare, living crystalline gem called Taydenite, intending to painfully mine the crystals straight off his body. Ben springs into action, using the sound-splitting powers of Echo Echo and the chilling, intangible flight of Big Chill to smash through Vulkanus's defenses. After defeating the villain and recovering the Rustbucket, Ben cracks open the retrieved alien tech to find a hidden message from Grandpa Max detailing the true scope of the Highbreed threat.
