Druggies Mom is starting to live in the reality of the Zombiepocalypse.
Her trip outside the fence where she saw the dead guy with the gun (who was not a zombie but had been shot) made her question what role the soldiers are playing. Then seeing the people in the house across the valley were signaling back to her and knowing the soldiers claimed no one is alive out there is starting to make her question what is actually going on.
On the other hand Travis (her libtard fiance who hates guns) is just a moron. I hope he gets eaten!
I give Madison credit for cutting open that fence and venturing out on her own. She was getting up close with the ZA underneath a car, staring dead walkers right in the face, and she handled it.
