What was the thought that ran through her mind? To bring out her bow at that moment, put an arrow in it, and fire the zombie's head so it would just die there without getting too close to her.
But come to think of it, before she does all these things, the zombie would have reached where she was standing and bite her...the zombie was too near to do that. She thought of it, and she knew it wouldn't be possible. So she'll just slay the zombie with her combat knives.
The zombie got close to her with its mouth open, it aimed to bite her neck at that moment. The moment the zombie reached where she wanted it to reach, before the zombie could do anything, she stabbed her right-hand knife straight into the zombie's left eye and drew it out immediately as blood was drizzling out.
