Granted, if Sasuke had a rash that didn’t alter the texture of his skin enough to discern through touch, it wasn’t like he could see it… But from what Aidou could see of his exposed skin, he was indeed clear. His hands were untouched by round, red rashes. Lack of evidence wasn’t necessarily evidence of anything, but in this case the symptoms of the Landel’s infection had become so visible to the naked eye that Aidou didn’t think he needed to check Sasuke’s blood. Not yet, anyway.

"I guess we can rejoice about that," said the vampire, adding, "I’m fine, too, in case you were wondering."

Though obviously Sasuke had been more occupied with slumbering his life away.

"Did you miss Landel’s initial warnings? People’s skin hasn’t been rotting away, but there have been flu-like symptoms that have been getting progressively worse. The infection’s in their blood. Tonight some misfortune individuals are set to undergo the transformation, or so he says. I was half-afraid it’d be you."
