My characters are investigating a couple murders, and are thinking it could be a member of the Templars, which in my story were mass killers of supernatural beings. My characters are mages in a city full of mages (still trying to figure out how to pull this off. The setting world is like ours and supernatural creatures live in secret.) They are in the city to be trained, but its more like a college, as most characters attending are 18-20. Despite their magical talents, they are still normal psychologically. Most anyway. The murders just began and they saw the corpses of the first two and failed to save a third who was in a kind of Jigsaw trap situation. Several other similar murder reports show up on the news. The protag has no instinctual shock and the violence seems strangely familiar to him (this was covered in another thread) and one demon possessed girl has absolutely no reaction to it at all, but the other characters are freaked out. One even pukes. So what I want to know is, what could make them follow the protag on the investigation? I was thinking that it could be since they saw three of the murders themselves they feel obligated, or since most the killings are near the school. I am not sure either of those would make sense though to an average reader.
