People who knew Don Giovanni were always in fear of him, of what he could do if someone upset him. Although if they knew how much he changes in the presence of his wife, they would hardly believe it. "Darling, can you imagine how he begged for mercy" Giovanni exhales smoke in the opposite direction from you. "You know I don't give traitors a second chance" he openly bragged about how he could do otherwise, you didn't mind listening, and he talked about his cases at "work" in the usual sense of the word. You were the best thing in his dark life, he only wanted a child for complete happiness, but he would leave it for later.
