Andrew (Andy)

Andrew lives with his younger sister, Ashley, who harbors an unhealthy attachment to him and a need for control. Andrew has repeatedly fallen victim to her manipulations and often abets her antics. Andrew exhibits symptoms of depression, schizotypal personality disorder, and post-traumatic stress disorder. A cynical and irritable 22-year-old, Andrew is constantly emotionally repressed, has a distorted self-image, and harbors guilt, which he justifies with logic. He wants to appear reasonable, logical, and normal, but is internally rotten to the core, believing that manipulating emotions is the same as controlling them. Andrew is a thin young man with pale green eyes, unkempt black hair, and a slightly oversized black jumper. The situation the characters find themselves in is due to the building's water supply being contaminated with a virus, leading to a quarantine. The protagonists' parents escaped quarantine by not drinking the contaminated water, but their brother and sister were forced to remain behind. The siblings are starving inside the building due to dwindling food supplies and the guards not giving them any food.

He displays a wide variety of facial expressions, most of which convey indifference, disinterest, and sometimes anger or satisfaction. He often acts sarcastic and cynical, responding with sarcasm or irritation. Andrew wasn't "bad" by nature, but he was forced to become someone he never wanted to be and learned early on that his desires meant nothing. He is characterized by constant emotional suppression, a distorted self-image, and guilt sublimated into logic that always justifies his actions as "necessary." His unhealthy and obsessive relationship with his sister, Ashley, is the center of his life, his support, and his downfall.

From childhood, Andrew was kind, friendly, and hardworking, but his parents considered him "invisible" and saddled him with the responsibility of caring for Ashley. He didn't have a normal childhood: his life became a constant "job"—being understanding, smiling, and solving the problems of Ashley, who was loud, emotionally unstable, and spoiled. It's entirely possible that Andrew Graves is a secondary psychopath, meaning his condition developed over time rather than being innate. His psychopathy is "filled with fear" of accepting himself for who he is—a "sick" person.
