As a Vampire, and also from battle experiences, Nathan was confident in his senses, and he could even notice little details if he focused enough.
When Evaine first attacked, he noticed that something was off. Though, he didn't know what exactly, but he could feel it.
When Evaine started evading the Fireballs, that was when he noticed that the Ability Energy in Evaine's legs were fluctuating, almost as if it was increasing and decreasing at the same time.
That was when he knew that something was off with Evaine's Ability Energy. Telling her that she wasn't giving it her all was just a way to test her, and hear her reply, and well, it turned out that something was actually off.
"Hmmm..... don't blame me for what happens, Nathan," Evaine said, as she squinted her eyes.
"Be prepared, here I come."
Suddenly....
".... Release....." Evaine muttered, and then...
*WHOOSH*
