"So you are King Daneel, after all. A pleasure to make your acquaintance. I hope you won't mind that I took up residence in your Kingdom for the past few days."
Hearing this, Daneel's eyebrows rose as he realized that he had fallen for the oldest trick in the book: confirming something by assuming that the other party was telling a fact, instead of a guess.
He couldn't even be blamed in this matter. Most of the techniques cast by the system only worked on those who matched its complexity. Hence, it was natural that his Camouflage technique could be seen through by someone who was a Champion.
The feat of breaking through the powerful formation protecting the Ancestral Grounds had led him to assume that this woman was either a Champion, or using a trinket. Thinking that the former was probably true and also because of the fact that the Matron had discovered his true identity and called him "kid" instead of the middle-aged man he looked like, he had given this answer.
