Aren stood there over Tristan's body in shock, he couldn't believe what he saw. In his mind he had thought of Tristan as a younger version of himself. So in one since Aren saw himself laying there. But the truth was it could have been anyone and that realization struck him even harder. He was barely aware of the others. He heard Ethan yell but his mind didn't process the words. Shock was the only way to describe what he was feeling at that moment.
The shock was broken as sirens of the incoming ambulance and police cars approached. Aren dropped to his knees and began to sob. He wasn't sadden by the death of his classmate, rather he was terrified. If some sort of gang had decided to make Switchville their new city of operations then no one was safe.
