When we get back to the drugstore our new objective is with Doug. Doug will take you to the area outside the drugstore and will show you just how grim things are looking. We'll do another step-by-step so we all stay together in these trying times:
Look to the right and see the zombie trapped by the telephone pole. Lee will do some detective work and make the comparison to the guy in the photograph and will come to the conclusion that that zombie has to keys.
In order to get to him you will need a distraction which comes in the form of the TVs across the street. You will try and use your remote on the TVs to no success... until Doug reprograms the remote and turns the volume all the way up. Alas only a few zombies take notice, not enough to make a successful run to the zombie pinned.
Now take that fire axe you picked up back at the inn and use it on the lock to open the door because nobody seems to know the combination to the lock they used to lock themselves in. Once you have this open take the brick and throw a Hail Mary to the glass holding the TVs.
Make your way to Lee's brother and you will have a nice conversation with the zombie. After five grueling axe-blows you can get the keys and make a run for your life.
Get back into the pharmacy and go to the back room when all of a sudden... ALARM! Next chapter!
