The five minutes that Daniel gave everyone has already elapsed and he was about to start making do on his threats.
Did they take the chance he gave them? Yes! More than a dozen of them came out and started looking for Alex so that they can preserve their lives.
It was inevitable. Do they know who Alex was? No! Then why should they care about him.
Those that came out knew that what they were doing was wrong. They saw the judging eyes that everyone gave them but they couldn't help but care less. Each of them felt that they have to be the devil in a situation where everyone is trying to be a saint.
Among those that came out were teachers and some students. They all came out with the same goal of looking for Alex but after five minutes of searching, they got nothing.
