Live on Ultimate Brain, teenage prodigy Harvey and his brother Seth are thrust into a public showdown after rumors swirl that Seth copies Harvey’s answers. A contestant declares he was falsely accused of cheating in a past life and vows to "rewrite my destiny" by uncovering how "Harvey... has been stealing my answers." The host offers two problem sets—one theoretical, one an application-based modeling task about a fighter jet. In a surprise move, Harvey chooses the application set for the first time in show history, raising the stakes and leaving the next round poised to decide the truth.
