Cassie slowly nodded when he said he wasn't sure if they would ever stop following them. How could either of them be sure? For all they knew they would keep coming after them until they slipped up and would kill them. It was hard to think about. Their life essentially was run or be killed. Nothing more, nothing less. She quietly put her hands closer to the heaters of the car and sighed, glancing over at him when he asked how she was doing. She merely gave a shrug, "Still a little woozy. Warm too. My fever might be going down a little, but I don't know for sure." She said quietly, turning her head to stare at the road ahead of them again. She indeed felt a little better, but she wasn't going to push herself until she was sure she really was getting better and this wasn't just some sort of adrenalin making her feel better. 

She too couldn't help but wonder why she hadn't turned yet. It had been at least eight or nine hours since she had been bitten. Usually people by now were turned and attacking any living thing they came into contact with, including the ones they loved and cared about. She glanced down at her bandaged arm, dabbed in red from blood that had seeped through before, probably ready to be changed as soon as they stopped, which would be a while. At least until they put enough space between them and those aliens. Leaning back slightly, she looked back to the road, speaking again, "Do you....think me feeling a little better is a sign I'm about to turn?"
