Despite the wrath inside, despite the burning intent, Rex didn't lose control.
He kept his composure, no, he needed to keep his composure.
Going berserk now would be catastrophic—he could end up destroying the Mahkam Ruin.
Destroying the ruin wouldn't be easy, but with enough anger, he reckoned he could do it.
