Eagle eyes indeed. Those are the kind of eyes that Kaiba catches the scarring with himself, but not on the wrist. Yuugi's hands...there's more scarring there than even at the site Kaiba had bitten! How? Why?

...Neither seem that important yet, but he won't forget this. It only...whenever Yuugi's near, Kaiba feels as if his insides are being wrung out, and whatever hunger he felt was sharpened along the whetstone, a sword ready to pierce both of them.

He reaches out, take's Yuugi's hand in his own and...they're so small. Yuugi's hands are small and frail and so easy to break.

(a flash memory hits, a blossoming of agony as he's thrown against a wall and he feels himself snap like a twig)

Kaiba shakes his head. Strange...and painful. But ultimately not what matters.

He glances at Yuugi's ring finger, but instead of biting, he presses the tip of his thumb nail

(claw)

against the first joint. The tip of Yuugi's finger...which gives way all too easily to the drag of that sharp point, opening a line that wept droplets of crimson immediately.

Kaiba felt his stomach twist, heard the noise it made. Impossible. It was impossible to be this starved again, but the pallor to his skin, beyond even his usual, and the way his eyes and cheeks looked slightly sunken? It's not as bad as when he was in Yuugi's room last night, but it's not too much better.

His fingers tremble as he searches for Yuugi's eyes, not to ask for permission--permission's given--but to ensure he was ready for what was to come.
