[That isn't a normal reaction, yet Sasuke struggles to place what it could mean — whether it suggests a deeper, lingering trauma to having his own blood drained, or whether it is something else. Stiles has endured too much in the past few weeks; it wouldn't be a reach to assume that his sensitivity to violence is heightened overall. Still, the reasoning doesn't quite settle in his own mind. It feels like there is something else laid underneath the dark of the boy's eyes.

The knife doesn't hurt at all, more of a pinch than true wound. He's bitten his own thumb countless times on the battlefield, let alone actual injuries he's suffered, so he looks indifferently at the swell of blood drawn. More important is Stiles' reaction — and it does not seem the boy is suffering any bloodlust.

Before the band-aid can be administered, Sasuke lifts his hand and licks off the drop of blood. Again, habitual as he would a nick he's created on his own finger for use in jutsu.]

I don't believe it would be in her best interest to turn you, if she could simply feed on you in the future. It would be smarter — to maintain that food resource. But I don't know what her motivations actually are.

[He watches Stiles, however, through that explanation, and through the gentle care of that band-aid wrapped around his finger. Needless, but kind.]

No. You can continue. What is it?
