First plot idea

Okay,here's my first idea for this sequel.It should be a direct sequel in which time is fast-forward about five years to when Carol Anne Freeling is in college and she has finally moved on from the events of the first three movies,but is putting her experience to good use as a paranormal researcher and she goes around helping other people that are in the same situation her family was in,so much so that it triggers here memories of the events of the first 3 movies and that brings back the Reverend Kane.The pro to this idea would be that you get to continue on with the story-line,but the con would be how to explain why Kane is back,after Tangina led him into the light at the end of the third movie
