What does Cole think is the answer to Peter's problems? Why does he think that is a good idea?

Cole thinks Peer needs to come to the island. Edwin has told Cole that Perter has tried to kill himself. Cole now recognizes this pain and thinks it is time for Peter to heal as well. Cole has learned to forgive and it time Peter also let go of his own pain. Cole knows Peter's problems, like his own, run deep. The island, although tough to live on, offers reflection and, with the proper attitude, healing.
