Despite what you said above about writing Claire, I love reading your take on him -- there's just something about his boundless confidence that's appealing and wickedly sexy, and you really manage to get that across.
Also, I love the affection and brotherliness between them. Even when they're having sex. It's so adorable. ...as is, oddly enough, the talk about killing. And the "big tough mobster" line.
Small typo: just as luck loses control -- Luck should probably be capitalized.
