She was confused. Then again, there hadn't really been a moment where she wasn't since she had been reunited with him. But she was ever more confused now. Most of his actions, his words, his expressions, they were the complete opposite of what she normally expected from a person. He kept her mind on the edge, but whether or not that was a good thing or not, she couldn't be sure. She wasn't used to not knowing what to expect, so she didn't know how to prepare herself. Perhaps that was something he would teach her with time. For now, she would just go with whatever he said, trying not to show him how completely baffled she was.
She sighed when he disappeared. What was he up to now? She heard shifting in the other room, a clear indication that he was looking for something. Maybe it was another story, or just an old memento that he wanted to show her. She waited patiently for him to return, confused, once again, when he came back with only a paper and pen. He set them down in front of her and explained what she was supposed to do. For a moment, he may have seen just how confused she was, but she turned her head away from him so he wouldn't be able to see.
10 worst things to see? She didn't know. Perhaps just her small childhood fears coming to life? Or maybe even some particularly bad dates that she had made mistakes with coming after her? Those seemed small and insignificant compared to what he'd seen. She didn't want him thinking she was afraid of what she might see in the future if she stayed with him, but she couldn't think of anything.
Then it hit her.
It hit her so hard, she dropped the pen. She was frozen, unable to move. The one thing she would never be able to handle. Not now, not in the future. Not ever. She couldn't bring herself to write it on paper, fearing that if she did, it would become reality.
After a few minutes of sitting like that, she was able to bring herself back around slowly. When she could, she grabbed the pen and scribbled down her worst fear. After she did that, she flipped the paper over and set the pen in the middle of it. Then she got up and walked out of the house to recollect herself.
In scribbly, shaky hand writing, she had written 'I would not be able to handle seeing Zephyr dead, no matter how he died.'
She wrote that same sentence to fill all ten spaces.
