If I'm not mistaken, this is the first comic that just Jules and Zoey in it together.
Zoey is an expert when it comes to zombies. She's grown up in a funeral home and been in a relationship since she was 18 (minus the time George and her were broken up after he was receased). Jules is taking full advantage of her skills.
With the attacks in the last week (from the zombies getting out) it's a very important skill to have.
We're setting things up for future stories before we get back to the main focus of this arc which will help us wrap it up with a bow.
