Arex found himself in a situation in which he was still trying to determine whether or not what Grecko had just told him was some kind of prank. All the while, he was left with a look of deep confusion.
"I will not be fooled by this ridiculous joke." Although he appeared to be in an awkward position while facing Grecko, Arex even let out a sarcastic laugh.

"Do you honestly believe I have the luxury of wasting my time on a frivolous joke, when I am fully aware of the imminent danger that threatens my home?" Grecko swiftly responded, making it clear that Arex's perception of him was incorrect. "I can't compromise Necropolis more than anything."
