[So naturally where here is a vampire, there's also a hunter. Of course, Yuuri isn't out hunting at the moment - at least, not for another person. Instead, he's sneaking around trying to get back to his proper side.
And that's when he hears the crying and, well. erm. oops. He's on guard, but he also doesn't want to interrupt because... hey, he knows how it is.
Of course, when he spots Fai, he does pause if only because... sometime seems slightly 'off' to him. And as a hunter, he's learned to trust that gut instinct. But still, he doesn't necessarily want to linger.
He's stepping back, intent to sneak away before he's noticed when, naturally, his heel steps down on a stick and it lets out a loud snap. Oops. Amateur mistake.]
