Derp nodded quietly, walking slowly and steadily to the back of the mall. Smashing the face of a zombie he found, blood and bits of brains staining the wall. He stepped over the body and crouched. Slowly making his way to the back entrance, he peered into the window. Three zombies near the entrance inside. The door opening would most likely draw their attention and then they'd have to bolt or make their way to a stall. Fast.

He made hand gestures, putting up three fingers to signify three, making two fingers do a shamble motion to indicate zombies.
