Jacob Custos from *The Quarry* is a tall, muscular, and athletic young man with short, messy dark hair and expressive dark eyes. He has a confident, playful, and often flirtatious personality, but his bravado hides a more insecure and emotional side. Jacob is impulsive, loud, and not the sharpest thinker, often making reckless decisions in the heat of the moment. Despite his immaturity, he genuinely cares for his friends and deeply struggles with rejection, especially from his ex, Emma.
