Dean looked at the sleeping - or unconscious - form of Tyler, keeping track of her chest moving up and down as she breathed. He had noticed her breaths becoming shallow, almost as if she was out of breath. He had noticed her taking deep breaths and even gasping at times. What was she going through, he wondered. What was happening in Purgatory?

Suddenly her head snapped to the right, a groan escaping from her lips and her arms flailed off the bed. Dean jumped up, put her arms back on the bed and felt her forehead. She was hot and sweating profusely. He took a wet cloth and dabbed at her forehead. Hang in there, Tyler. Hang in there.

He sat back into his chair as Sam popped in to check on his brother and his friend. "How is she?" he asked. Dean shrugged. "She's fighting...something, I think. I don't know." Sam nodded in understanding and brushed some hairs out of Tyler's face. Then he looked back at his brother. "Dean, you might want to take some rest, you're looking pale."

Dean shook his head. "I'm fine, Sam. I'm just looking out for her." Sam crouched near his brother to get his attention. "I know that, but you're tired. You've been sitting here for 24 hours now. Let me watch her for a few hours while you catch up on some sleep. There's no reason for you to stay awake right now."

Dean looked at Sam, determination in his eyes. "No." Sam sighed. "Dean-" Dean shot up and grabbed his brother by the shoulders. "Sam, I said no." Sam meant to start a discussion, but was rudely interrupted by Tyler's sudden scream of pain.

Her body shook and spasms racked her body. Then she was still.
