She saw her human cry for the first time after the world fell, although she didn’t know why he was crying, since he seemed to be unharmed, and she had found a safe place to hide, feeling the bumps as the world crashed but not hurt beyond that. As he held her tight in his arms, in a constricting way she didn’t like to be held, she realized that he was crying because he had lost her and now he had found her, so she grabbed his shirt with her claws, holding on tightly to him as well, because he had found her but she had found him too. Even as the world crashed and its broken remains were all around them, it was her job to comfort him, to let him know that he was safe.
