Following the Cynthia incident, Ed and Lorraine Warren were shaken into re-evaluating what they were doing here. Fascination and information building were honorable pursuits, but not when people could be hurt.
That was the thing - until now ghosts had been something other. They weren't thinking, feeling individuals. A major point had been missed, which was these were actually human beings. They'd just shifted form. They had consciously survived their own death.
The Warrens, and the New England Society for Psychic Research, had been acting like tourists in other people's tragedies. They'd been ignoring cries for help, because they hadn't recognized them as such.
Ed began a frenzy of meetings and telephone calls. He started from the viewpoint of 'who could I call for help in these situations?' Then went for it.
Hours of conversations with priests and theologians ensued, alongside discussions with those who may have aided these people, if they were alive. Psychologists, social workers, police officers, all the emergency back-up for those in distress.
Armed with reams of knowledge and advice, the Warrens now shifted their focus. They were there to help, not as voyeurs, but as a kind of paranormal social service.
Moreover, Ed had been warned by Catholic priests that not every haunting was the benign remnant of a human in distress. Some of them were much worse. They were demonic in origin, either due to occult activities taking place on the site or a direct approach by some Hellish force.
As the decades passed, and the couple's experience grew, they were to encounter cases like this. Ed Warren trained as a demonologist, in order to deal with them, though the couple always deferred to the Church in perceived worst case scenarios.
One criticism of the Warrens is that they became quicker to reach conclusions involving a demonic entity over a bog-standard haunting. It was thought that their own strict Catholicism meant that they lost objectivity here.
Or it could have been lots of demons in modern day America.
