There's a couple side Jack stories to come in this arc and I wanted to give John and Lyn a few moments to breathe after the Glenda incident before hurricane Jack comes to town. A while ago I did one of the Zombie Survival Guide things where it's Chainsaw Body Spray instead of Axe and this was just a nice call back to that. Chainsaws are more zombie appropriate than axes for some reason... I blame Bruce Campbell.
