Shelby wouldn't treated any other girl the same way.

A prank similar to the pep rally stunt would've been played on any girl at the school who was secretly hooking up with Austin.

Her revenge plot wasn't about Sam working in a diner or being a geek, it's about her being jealous and bitter over Austin, and if she couldn't have him, no one could.

She would've turned against the step sister twins if too if they got away with posing as "Cinderella" at Austin's job.
