Strength and confidence in herself.
This event forced Klam to be strong and courageous. With her first dog, Otto, she had time and just herself to cry, to feel sad, to do nothing, but not this time. She has a family, a husband, which she now cherishes all his sacrifices for her, and a daughter who is depending on her. She realizes that the relationships are important and must be held dear. And Yes, when it's time to say goodbye, it will be harder but it's because there's so much that she'd learned from Moses and so many experiences that they had together, and not just because she helped him out of horrible living condition. Klam knew this and took it into deep thought from this moment on.
