When the bars came down Erin reclined in the bus seats and smiled at the sudden acceleration of the bus but started laughing at the boy who had flown back. Since Gretchen was talking to the new kid she busied herself with an experiment and started matching her body's kinetic energy with the energy of the bus. She looked out the window then closed her eyes after a minute of getting the feel for the force and gradually increased her own till it was perfectly even with the bus's, "I bet I could go head to head with this bus and stop it" she said in a low tone and pushed the seat watching it bend without offering any resistance. After she pushed it back up Erin looked at the boy who's whole hand was almost completely covered in a shiny coat of what looked like metal, wow that's pretty amazing.... and flashy" she said.
