It appeared the relationship between Aidou and Aigis wasn't quite the same as how Aidou chose to interact with Sasuke, as Sasuke had initially assumed. Given that the vampire had been talking about the taste of the illness earler, Sasuke rather dryly shifted his assumption towards a link that was more like those on the food chain.

That evidently meant that Aidou had qualms about bringing her to the basement -- to protect her, or to prevent her from learning what meagre information that might be available? Sasuke himself had no particular interest in keeping anything about the Institute secret nor in not securing someone with the ability to heal when travelling into new territory. Not least because he could distinctly recall the last time someone had gotten hurt when he'd worked with Aidou and what had followed.

Though this time there would be no Naruto to talk too much. That was hardly a loss, and given that this Aigis seemed more shy than liable to blab, Aidou had better have a decent reason to reject her company.

"Decide between you whether she comes or not," he said shortly, what little social grace he'd been showing wearing away to imaptience. "We need to move soon."

Preferably before the night ended for once.
