Despite it the doctor perfectly well copes with the duties and doesn't concede in anything to the professionals who passed special training in Vatican. Seth devotes in total himself to work, helping the patients to get rid of the dark force devouring them. Contact with consciousness of the eleven year old boy in whom the demon of improbable force was installed becomes its next business. Here only the doctor doesn't know yet that he should deal with evil spirits with which one he was looking for some years.
