Extend the Story - Add a Room

You have regained all of your supernatural strength (not all of your powers though), you put it to good use by giving this man a piggy back ride (an average height vampiress carrying a full grown man on her back, nice).

You were about to make a move towards the back of the grocery store, but you realise that one zombie (missing an eye, the flesh of his upper arm torn off) is a few feet away from you, shambling towards you for your human.

A zombie is no threat to a vampire so you completely disregarded it till you took this helpless human into consideration.

How do you get rid of it?

Stab it thru it's skull with your bare hands, destroying the brain
