Jack, in his late 40s, bears a rugged, weather-beaten face marked by the passage of time. Despite his age, there's a hint of clumsiness in his demeanor that adds to his charm. His square jawline and determined expression contrast with his occasional sheepish grin, while his short, tousled salt-and-pepper hair speaks of a life filled with adventures. Despite his quirks, there's warmth in his green eyes and kindness in his smile that makes him endearing to those around him.
