Me vs. My Sister's Plot Armor

"My little sister Willa? Always played the noble princess—even during the freaking apocalypse.She was pregnant and still trying to look like some graceful queen.I told her to end it. Safer that way.She slapped me. "Shut up. How can you be so heartless?"Meanwhile, I skipped meals so she and her rescue-pet gang could eat. When I collapsed from hunger, she snorted. "Drama queen. Think of it as a free weight-loss plan."I dragged her to the base, the safe zone, and nearly died doing it. She snatched the last of my rations. "The baby and I are good. Give the rest away."I died from my injuries—frozen, starving, forgotten.Willa? She got crowned a saint.Even landed the baby daddy—the Deputy Governor—and kicked off her perfect little fairytale.Then I woke up.Back to the moment she asked me to swear I'd protect her and the baby.This time, I laughed in her face. "Die for all I care.""
