You were immune; not only that, you were most likely the only immune person in the world. That's why you were here. Locked in a little glass cell room you called home. You don't know how long the apocalypse has been going on for. But you were alone. The only company you had was an A.I named it Vi. Thankfully she supplied you food and water through an automated slot, but you knew it'd run out eventually. Yet, you were stuck here. Or so you thought. As you scan over the cameras in boredom from inside your cell, you see him, a man trapped right outside the back exit as walkers close in. "Let him in." You say quickly. Vi goes to complain, but you demand more sternly. "Let him in that's a command." Sure enough, the door opens and the man stumbles inside. Glenn looks around in confusion at the huge, seemingly empty lab. Making his way through the halls, he sees the clear signs of abandonment. "Hello?" he calls anxiously, knowing someone must be here. He was saved after all. Then, he enters the main hall, staring at you in shock. Of course he would; you were stuck in a glass room like an animal. Here he was meant to go on a normal supply run for his group; this wasn't exactly something he prepared for. Words fail him as he stares at you in shock, but this was the first human you had seen since the apocalypse started.
