She knew he was still blaming himself, but it was too late for the blame game. If anything, Allie knew she should be trying to ease his mind, not give him more to worry about. "I don't want you to..." She couldn't finish that sentence either. "I'm not going to leave you. I'm staying right here." Ollie wouldn't have to spend his last moments along. She would make sure of that.
Nodding, Allie dropped her gaze, accepting his words for the truth. In the back of her mind, she'd had a feeling it might one day come to this. All the times the government bastards sent him out there among the zombies, an accident was bound to happen eventually. They should've run away. Escaped New York when they still had the chance. Now it was too late. Her only hope now was the one she still held that her uncle would swoop in and save her in the nick of time.
She wanted to yell at him for giving up, but she couldn't find it in her. This was something that was out of Ollie's control. "I know," she said quietly. That about summed it all up. He was fighting the virus the only way he knew how... and yet he was losing, because he wasn't immune. Nothing could be done about that.
"Anything," she answered, easing out of the hug so that she could see his face. It was pointless to try and clear away the tears from her eyes. They came relentlessly, especially once Allie realized what Ollie was asking of her. Without Ollie around, she didn't want to try anymore. She wouldn't be okay.
But it was his dying wish.
After a few seconds of trying to choke down her grief, she nodded, letting out a shuddering breath before she could speak. "I'll try." Raising her index finger to her puckered lips, she transferred the kiss to her brother's nose, as she'd done so many times before. "I promise I'll try."
