I'm Just Humanity's Spare Battery

During the fifth year following the zombie apocalypse, my father becomes the base commander. It is all because Beckett Walker, my younger brother, and I both have antibodies in our blood that can counter the zombie virus. Mom and Dad give the majority of the supplies and resources to Beckett, because I'm just his "backup". But since I'm the backup, I'm still fed and provided for to ensure that nothing happens to me. However, when I accidentally take the food that was meant for Beckett, Dad slaps me in anger. "You already received your portion of the supplies, so why are you trying to steal Beckett's? He's not only your younger brother, but he's also the hope and future of the base!" Mom shrieks at me, "Are you trying to kill your brother so you can take his place?" I want to refute them. I only took it by accident. I didn't do it on purpose. But before I can, Dad locks me up in the cryopod. It's dark and freezing. I curl up in a corner, my body shaking. I'm sorry, Dad. It's so cold. I promise I won't ever be greedy for food again.
