Is that so? Yisen Gard indeed noticed quite a bit.
Ian carefully observed the blond youth before him, pondering how the other had deduced it... Was it through Master Gossay's words and actions? Or perhaps from some subtle clues hinted by the Second Prince? After all, Michael hadn't particularly concealed his intent of being the alchemical inheritor of Inega II. If Yisen Gard misunderstood this, yet arrived at the correct conclusion, it wouldn't be surprising.
Or was it that Yisen Gard, using his mother's channels, or perhaps his own, noticed Ian's flaws from his formidable past combat prowess and actions when living together in the Imperial Capital? After all, he hadn't hidden much in the South Sea Great Labyrinth; anyone would be curious about such a powerful First Energy Level.
