Javert's just aware enough that they should probably be quite, so he doesn't repeat Karis' name - although he worries that he'll soon enough forget it otherwise, like he's apparently forgotten everything else thus far.

But he's a clever zombie, despite not really knowing who he is or what he's doing here or anything besides hunger. He doesn't go straight into the restaurant but instead walks around it, casing it out. And when he sees the chairs at the patio, he tips one over and starts to drag it, then, uncoordinately, arduously, jams it to block one of the doors.

Two entrance-exits from the building. Now there's only one.

"Other...side..." He gestures with his hand to the other door. Their prey is within. He shuffles over to the other door and tries to shove it open - only to realize that, to their luck, it isn't even locked.
