That door was not there before

The Steel ThresholdThe warm orange torchlight flickers violently along the jagged stone cavern walls. While the terrifying, careca long-armed zombie stands holding the human skull with its mouth wide open, Daryl Dixon, Abraham Ford, and Glenn Rhee turn around and sprint desperately away down the dark rocky corridor.They run without stopping, their boots kicking up dust, until they spot a stark contrast ahead: a highly modern, heavy industrial steel door embedded right into the ancient stone structure.Abraham charges forward, grips the modern metal lever, and violently pulls the heavy steel door open.The trio scrambles inside the futuristic facility, and Glenn helps Abraham slam the solid metal door shut, engaging the heavy electronic locks. From the other side of the thick, sealed steel barrier, the muffled, echoing screech of the careca chain zombie rings out through the vents: "Mother!" #thewalkingdead #Abraham #Glenn #DarylDixon
