I think it was what Kieran CHOSE to do after the storm that made him kinder. How easy it might have been for him to stay in Evelyn Bay and pick up where Finn left off- -like Sean did taking over the diving business. He could have stuck around out of a sense of guilt and allowed himself to be emotionally punished by his parents every day for the rest of life. (That would not have made me kinder!) Fortunately, a doctor, who was examining Kieran physically, counseled him about the "thinking problems" he might experience. Thank goodness he really listened and found a way to do exactly what she told him to do. I think it was important that Kieran left the island. He met new people, had different experiences, and expanded his view. He was also not afraid to ask for help when he needed it. I appreciated the honest, sometimes difficult conversations Mia and Kieran had with one another. There were a few times I thought, "Uh oh... he is going to mad at her for saying that!" Kieran never did get upset though. He listened to what Mia had to say, and instead of reacting quickly, took the time to process what she was saying. He seemed more willing to look at the other side of the issue. He was less judgmental than a lot of the island residents. Even if he was being berated or overheard nasty things being said about him, he tried to put himself in the other person's place in order to understand where they were coming from. The personal work he had done, a new location, a supportive partner, and becoming a father helped Kieran see the bigger picture- -the world outside of himself. All of this made him kinder.
