Question: What does the ending of the movie mean? It has nothing to do with the 3rd movie like you'd think it would.
Question: If Parker was possessing Josh throughout the whole movie, why didn't he just kill Josh's family right off the bat instead of waiting until close towards the end of the movie?
Answer: He answered that while chasing Renai, it was because at first he didn't really want to but his mom kept planting seeds in his head and telling him that if he doesn't he's going to die and towards the end you can tell he was very close to dying so he gave in and try to kill the family. Also throughout the whole movie it talked about the fact that his mother basically forced him to kill people.
Chosen answer: The third movie was a prequel to the first 2. It was done to set up an explanation in case they made another movie that takes place after part 2, so her appearance after she died made sense.
