Rachel's

Rachel learned that if she pressed the watch's plunger, it seemed as if time had stopped, but after seeing water very slowly spray from a sprinkler, it was as if she was moving 100x faster than everyone and everything else, like The Flash. If she lifted something and let go, it hung in the air, but in reality was falling very slowly. No one could see her.

As she walked to her first class, she spotted Brooklyn Mason and Stephanie Briggs, two of the girls who mocked her. They were walking to class.

She stripped Brooklyn from the waist down and Stephanie from the wait up.

She then neatly folded their clothes and put them on the sidewalk twenty feet in front of them.

She took out her phone to film the bitch's reaction and restarted time.
