Should Peter come to the island? Consider different perspectives. How would it affect Peter? How would it affect Cole? How about the family members?
I think that Peter would be scared if somebody asked him to join Cole on the island because Cole was the one who beat him up crazy. What Cole had done had probably scared Peter for life and Peter might never be able to for give Cole for what he has done. I think if Peter came to the island it would affect Cole by showing Cole how he feels but at the same time Cole might be able to show his change, apologize to him and tell him what happened along with how he now feels. I think Peter's family members might not trust Cole to be with Peter because of what Cole did to Peter and because of all of the lies that Cole has told.
