"How has Layton not snapped from all the trauma" because his story is that of grief and acceptance. He's known pain and has suffered from it but after many years he learned to move on because life will continue whether he wants it to or not so he may as well make the most of it. He carries the painful memories with him but is also capable of seeing the beauty in life. He cries for his loved ones who have died but appreciates the people he has in his life now. Layton is an amazing character BECAUSE he hasn't snapped.
