No one could even detect the enticing aroma of the lunch Aston brought; instead, the sight of the food made them feel nauseous. After witnessing the gruesome scenes outside the wall, particularly the aftermath of Kisha's actions against the zombies when Sparrow's team departed, their stomachs were in turmoil. The contrast between the horrifying reality they faced and the appealing lunch only served to heighten their discomfort.
Even the seasoned veteran soldiers, who believed they had witnessed every conceivable horror, found themselves unable to eat outside the wall. They feared that even if they returned to the cleanest environment inside, the vivid memories of the gruesome scenes they had witnessed would linger. They imagined that the lingering stench of rotting flesh and the unsettling sensation of squishy brain matter, encountered while extracting crystal cores from zombies' heads, would haunt them and make it impossible to enjoy their meal.
