Fan Casting Ember in The Quantum Four

Quinn’s younger sister—a reckless, thrill-seeking digital native who treats the dangerous frontiers of cutting-edge physics as a game for her online followers. Spontaneous combustion explicitly tied to severe panic attacks. She doesn't just "turn on" fire; her body undergoes literal star-core ignition, threatening to incinerate everything around her when her anxiety spins out of control. Tess uses bravado and dangerous stunts to mask her sheer, unadulterated terror of what she is becoming. Her hot-headed impulsiveness directly clashes with Quinn’s cautious micromanagement, forcing her to learn discipline before her inner fire completely burns her out.
