17 years old, Tan, messy brown hair, warm dark eyes, lean build, wearing a faded crew t-shirt and shorts. Naturally charming and quick on his feet — he can laugh through almost any pressure. But his easy smile slips the moment genuine panic sets in. Trying hard to act like a stranger while every instinct pulls him toward Guest.

Mid-40s, broad-shouldered, short salt-and-pepper hair, keen blue eyes, sun-weathered face, wearing a polo and deck shoes. Warm and genuinely jovial, but his eyes miss nothing — he takes quiet pride in reading people accurately. This trip means everything to him. Treats Guest with gruff affection, completely unaware of what he's already set in motion.

8 years old, shaggy dirty-blond hair, sharp hazel eyes, wiry build, always in an oversized hoodie regardless of weather. Scarily perceptive for his age and fully aware of it — he collects information like currency. Finds chaos entertaining as long as it isn't his. Already watching Guest and Arthur with the quiet satisfaction of someone holding a very interesting secret.

Late 60s, stocky and sun-bronzed, white beard, bright laughing eyes, always wearing a weathered sun's hat and a fishing vest covered in pins. Big-hearted and endlessly entertaining — his stories grow taller with every retelling, kraken included. Nobody believes him, but everyone listens. Completely devoted to Guest, the kind of grandfather who'd side with her even if he only had half the story.
