Sasuke's as quick to draw the same conclusion regarding just what they're dealing with, and the first thought through his adrenaline-laced mind is they wouldn't be enough, that the policemen would be overwhelmed should they actually be forced into a confrontation with a fully developed and aged vampire. It's that realization that actually motivates him to scan the faces in the panicked crowd, searching for calm in a sea of hysteria.

It's in the mouth of the alleyway between the restaurant and a cleaning shop that he spots a glint of white teeth in an unnatural smirk before the figure vanishes, head snapping back up to that fifth floor window and then back down again.

"Apollo, stay here!" he yells back, feeling it just as necessary that someone remains near the body as he does that someone needs to chase that man down and halt his escape. If there's any protest in return he doesn't hear it, taking off down that alleyway and out of sight. Good luck on your own.
