When Akari opens the fridge, she sees that there is no more blood.
But when Sophie tries to order it on her regular delivery site, she's met with a note that the service is currently inoperational.

Everybody is agonizing about what to do when Erie starts talking about finding a human downtown who wants to have their blood sucked...
Slowly get on your knees 
and put your gun down.
.اجثُ على ركبتيك وأخفض سلاحك
Langsam auf die Knie
und leg die Waffe hin.
Arrodíllate lentamente
y tira la pistola.
Arrodíllate lentamente
y tira la pistola.
Genoux et arme à terre !
Inginocchiati lentamente e metti giù la pistola.
Ajoelhe-se lentamente e solte a sua arma.
Опустись на колени и положи оружие.
