Samantha was glad she saw him taking off.  She watched til he was far out of sight before letting control go.  She had, for the most part, used enough energy to avoid the change into something dangerous.  She suddenly felt very sick from the focus.  She threw up when she tried to stand.  She headed back to the school, stumbling along the path.  She made it about halfway before succumbing to the dizziness.  She collapsed in the dirt, everything around her faded to black as her eyes slowly closed.  She had been fighting to stay awake.
