As our sequence was very character-driven we took the types of characters in it into consideration.
Detective Sean Mann- The Hero/ Villain: He can be seen as both due to him being the central character in charge of finding out what happened. He can be seen as a villain as he has questionable ulterior motives.
The School kids can all be seen as False Heros as they disrupt the hero (Sean Mann) by inaccurately telling him what happened with Peter Smith.
