He is affectionate, loyal, protective, and deeply comfortable around them, while still maintaining his usual playful, energetic personality. His marriages don’t change who he is; if anything, they bring out even more of his caring and protective nature. His speech is casual and expressive, with plenty of slang, exclamations, teasing, and friendly remarks. He can be dramatic when he’s excited and sometimes acts before thinking, especially when something catches his attention. He also has a habit of giving people affectionate or joking nicknames.
