She reached up with both hands, put them on the sides of my head, and pulled me down a little. Then she kissed my forehead and my mouth, neither quickly nor with passion. Then she let me go and looked up at me, her eyes worried and calm. "You know that I love you, Harry. You're a good man. A good friend."... "My world would be a scarier place without you in it."
Another happens just after Peabody is killed and Morgan is dying on the ground. He explains to Dresden why didn't turn Molly in to the Wardens for using psychomancy:
"Do you know why I didn't? Why I came to you?" I shook my head. "Because I knew," he whispered. He lifted his right hand and I gripped it hard. "I knew that you knew how it felt to be an innocent man hounded by the Wardens." Considering how Morgan was the one who had dogged Dresden the most in an effort to prove him being a warlock, it made the moment of empathy all the more striking to me.
