It looks like that humanoid figure is completely different from those humanoid Monsters. Also, that humanoid figure did not do anything other than observe the mansion.
Sam already notices that human by using his observation technique. He immediately realizes The Identity of that person because of the aura that person releases from his body.
It is the same as those elders, and with this, he already concluded that that person is also an elder like those other elders.
Not only that he is also very familiar with that spiritual aura. If he is not wrong, then some notice the same spiritual aura during the time when the Warrior Association decided to invite all the people from the mansion for the punishment ceremony.
That person was definitely the uncle of that first commander. With this, Sam already realized everything. Sam can easily come out from his hiding place to deal with that enemy, but he decides to slowly approach that person while doing nothing.
