Liz didn't hear what Chase and Zeke were talking about. When Sparky hadn't rolled back by, Liz had opened up the metal link between them to see what was going on. She had figure that he had managed to hurt himself...again, messing around on that thing. What she found was much worse.
All the back entrance doors had been sealed up. The only way out was an emerancy exit which was locked up tight. She wasn't sure if the zombies would be able to figure out such a thing anyway. "Now would be a good time to go to the back of the mall," Liz said out load. Then she turned her thoughts to Chase.
"We have some company outside and Sparky happened to roll out in it. Take Zeke to the back of the mall. It's sealed out. Only way something can come at us is the front. I have to check on Sparky and seal up the front doors before I join you."
Because if he wasn't okay, she was going to rekill the zombies. With that thought she switched her thoughts to Sparky. "Get your ass back in here now. I'm coming to keep seal up the doors."
