Hades eyes towards Faust while observing his body language and trying to evaluate his spiritual power. The advanced captains and maybe some captains who are sensitive to auras are able to calculate the spiritual power of the individuals standing before them.
Strangely, Hades did not sense any aura or spiritual power from Faust. And as he is examining Faust from top to bottom who is facing away from him, he catches Faust turning to his left and glaring back at him, with an unknown hunger hidden deep in his eyes.
Faust's face is facing forward but his eyes are glaring at Hades from the corner of his eyelids.
Hades widens his eyes at the fact that Faust is not looking away even after their eyes meet each other. "How can he stare at me like that?" Hades whispers under his breath, being surprised by the guts of Faust.
