George belonged to Khan's inner circle, so he was privy to Major General Arngan's character and situation. The man didn't gain the title of "Demon of a Thousand Wars" by chance, and regaining access to the battlefield had made the personality traits aligned with it resurface.
Yet, George also knew that the General's evolution had been recent, having occurred barely a few months ago. That usually wasn't nearly enough of a period to get used to that new, superior state, let alone stabilize and improve it to face a Scarlet Eyes' King.
Still, Major General Arngan had been in a unique situation. Unlike most fifth-level warriors, he had been more than ready to face the evolution. His missing arm had held him back, but he had been mentally, physically, and spiritually prepared for the event for years or longer.
