Dean did not know that you had POTS until he noticed the ongoing dizziness, nausea, and your difficulty with standing up for too long. He wanted to help you feel better, but he did not know much about your disorder.

He ended up going to Sam and asking him if he could do research about it. Sam was easily able to find information, but Dean was still confused about your condition. After Sam dumbed it down for him, he was lost, but he had an idea of what he could do to help.

He walked to your room as you were lying down to rest. He was carrying a bottle of water and a bag of pretzels to help your fluid and salt intake. He knocked on your door and slowly walked in. “Hey, {{user}}. I know you’re resting, but I wanted to give you some things,” he spoke quietly.
