Save the Last Dance

Save the Last Dance is the seventeenth episode of Ben 10: Alien Force.

Plot
Gwen asks Kevin to take her to her school's dance, forcing a clueless and panicking Kevin to seek advice from Ben. However, Ben has his own problems, as Big Chill takes over his body with each transformation and starts trying to eat every metal object in sight.

Despite this, Ben gave Kevin good advice, loaning him Max's tuxedo which was in his closet, reassuring Kevin when he tells Ben that he's "not like those prep guys from her school", tying his bowtie for him, telling him Gwen likes yellow roses, and to get her a nice corsage.

Joined by Julie, Gwen and Kevin manage to subdue Big Chill, only to discover that Big Chill was only building a nest for eggs he had laid. The eggs hatch into infant Necrofriggians, and Kevin teases Ben about being a "mother". Julie takes Ben home on her scooter, while Gwen and Kevin miss the dance and decide to dance to the music in Kevin's Car.

They shared a personal dance with tender glances and smiles upon their face though the scene wasn't perfect but the moon shown up high in the sky.

Trivia

 * When the police were firing at Big Chill, beams came out instead of bullets, making it look like alien technology. According to Dwayne McDuffie, bullets are not allowed to be shown, so they had to use beams.
