Wow. This really is an exciting chapter. Perhaps the best yet?

Lizzy should have just got out of there! She was just waiting with the mallers! I have a feeling the maller who was being nice to her (name escapes) will survive with her and the other guy will die. So then they will escape together and it will be a big deal because all of a sudden they will have a maller that Lizzy likes and was saved by, but he is still a maller. Or she could die...

So they are already out looking for helicopters. Back over to the other rooftop by the zipline again? That could be an exciting escape with zombies grabbing at the helicopter?
