Chad arrives
Finally, Chad had caught up to Emma and had seen the entire crash go down. He knew that this was going to end badly, he was just thankful that no one was killed or seriously hurt. He let the police know where they were and continued to record Emma and try to speak with her.
Just like the other man that she had crashed into, Chad could see immediately that she was under the influence of something. He asked her what she had taken and explained to her that she was a danger on the road and she needed to leave the car. Emma eventually stepped out.
