Someone came lurching out of the fog right into Jack's hiding place behind the store.

For a moment, it might have looked like the young man was attacking but when he saw Jack there he dove towards him and ushered him closer to the dumpster, pulling a rusted and battered trash can in front of them to help hide them.

"Down! Down! So they don't see you! Sssh."

Shadows were moving in the fog and he seemed to be trying to hide himself and Jack from them.
