As Zack faced the Dragon King's overwhelming insanity and power, uncertainty gnawed at the edges of his mind. He wasn't entirely certain if his plan was fully ready if he had accounted for every variable and calculated every risk. But in the heat of the moment, with the world-shaking around him and the Dragon King's fury bearing down upon him, Zack knew he couldn't afford to hesitate. That monster was willing to destroy its own world to take him down, after all.
With a determined set to his jaw, Zack made the decision to silence the enemy, to quell the raging storm before it could engulf him completely. Even if his plan wasn't perfect, even if there were flaws and uncertainties, he couldn't afford to let fear and doubt paralyze him. He had come too far, fought too hard, to stop now.
