That got the Chief's attention in a hurry - his armor shifted as he quickly looked up from the omni-tool and focused directly at North. Briefly, the idea that what he was saying didn't make any sense crossed his mind - as far as he knew, he was the only one who had an AI as a partner. Most if not all other UNSC AI were charged with maintaining ships and defense platforms - whatever function they had, he knew that his and Cortana's partnership was one-of-a-kind, or at least, it should've been.

But, there was no guarantee this guy was even from the same world as the UNSC, as bizarre a thought as that was. Just because he had recognized Cortana as an AI didn't guarantee anything. Still, he found himself on guard.

"She is," he confirmed. "An AI is hard to come by for just one person," he added shortly after. He was nothing if not curious about exactly how North had one, as he claimed.
