The term "not entirely human" confirmed two truths: Renamon somehow knew he wasn't normal child, and the method she used to uncover said fact involved something beyond casual conversation. Nigredo had heard a few Realians had the capacity to scan the genetic map of living organisms; perhaps this held the same concept. Then again, with multiple planes of existence involved (as she so conveniently mentioned), she could be utilizing something else entirely.

In either case, Nigredo did not like the arrangements of this exchange. Likely because at this point, he had little choice in the matter. "What makes you say I'm not human?" he questioned, almost defeated.
