John Rider's rescue of Yassen Gregorovitch has been changed from the books, but it's no less awesome — after Yassen panics and is held at gunpoint by the bodyguard of a Properly Paranoid target, John nails him and the target with a double headshot, then dispatches both other guards in a matter of seconds. No wonder Yassen still looks up to John and respects his son.
