Submission is a very strange act, Castiel thought, watching the humans below from his vantage point in heaven. Composed of... what? Trust and fear?

It was everywhere! In children obeying their parents, trusting that they knew what was right, and fearing that they'd be punished if they didn't obey.

In office workers obeying bosses, trusting that they knew what was right for the company, and fearing that they'd be fired if they disobeyed.

In most everyday citizens obeying laws set by policemen, trusting that in doing so, they'd lead guilt-free lives, and fearing that if they didn't they'd be arrested.

Everywhere Castiel looked, he saw submission. Why? Why do people show this? All it is, is someone saying that they are in a more powerful position then you. And just how could you both trust and fear someone at the same time? He shook his head, confused and trying to clear it.

Hey Cas, we need you! Rang clear in his mind. It was undoubtedly Dean. What did he want now? He was busy! Well... not at the moment. At the moment he was evaluating a strange common emotion. But he was going to be busy soon. There was a war on! Who knew when he'd be needed?

Despite this, Castiel turned his focus to the Dean. The figure was pacing and looked rather flustered. Flustered... Castiel thought, I must analyze that emotion too sometime...

Castiel! What part of WE NEED YOU don't you understand? Get your ass down here now or so help me, I'll track you down and kill you! He heard it, but he still didn't move.

Must be important. Castiel thought. To him at least. He wondered to himself whether submissiveness was what he was showing to Dean all the time. He followed Dean's orders... which he supposed counted as trusting. And did he fear him? Nah, Castiel thought, I'm an archangel. Why fear a human? But still... there was something about Dean... Castiel pushed it from his thoughts. An angel of the lord? Showing submission to a human? Impossible.

When Dean's voice reached into Castiel's mind again, he sighed and decided to pop down just to see what he wanted. Submissive? No... he was just... curious. Yeah, curious was the right word...

He disappeared with a final thought. Curious...
