Ash has attempted to expose Ethan's secret. If she's correct she will earn all of Ethan points. If she is incorrect she will lose 750 points and Ethan will earn 750 points.
Ash thinks that Ethan's secret is that he's not Ethan.
Unfortunately that is not the actual secret of Ethan.
Ash loses 750 points while Ethan earns 750 points.
But that doesn't mean that the secret is far off. Better luck next time.
