From Above (closed to Cas and Sadie)

How did one breathe again? Sadie was having a hard time figuring this out as she lay in her bed after school that day. A storm cloud, above her head. What was that? What did it mean? She was still soaked- she realized that she should probably change before Vivian or Lucas asked why she was wet.
She didn't want to have to explain the episode at school.
Oh my god, I can't ever go back! I'm a freak! Sadie figured that if anyone truly important knew, she'd probably be sent to a testing facility. That's not what she needed, especially not today.
Why is breathing so hard? Sadie struggled to calm down, even an hour after her scene at school. What was she going to do? How would she hide this?
What was she?

"What happened?" A voice said, in a low tone.

Earlier that day, Castiel was off doing angel things. Well, he considered himself an angel. He was actually a Celestial, which was just about the same thing. He'd saved some people, but now he was just being generous. He didn't usually go around Earth on helping sprees. He even helped some of the homeless. Sure, he might have done some reality shifting here and there, but he did what he could. Earth was very interesting to the Celestial. It was still quite new to him, the customs and such. He tried listening to some Earth music and from what he understood, humans seemed to be very fond of their glutenous maximuses. They usually called it butt, or something of the sort. Now he was with some random girl. She didn't seem very human to him, he could tell these things. He'd appeared by the girl's bed.

"Excuse me?" Sadie questioned. As if today wasn't weird enough. Now this random person shows up in her bedroom? Asking what happened?
"Who are you?" Sadie couldn't help it. Along with being a bit frightened, she was also intrigued by this stranger, maybe he could help her.
"You know anything about aliens?"

"I'm Castiel. An angel of the lord." He explained. Except this was only half true. This human was surprisingly okay with Cass being there. He thought she would have reacted much stronger. Oh well. If anything, this made his job easier. "I know everything about Aliens. I'm almost Omniscient." He told her. That was also kind of a lie. He never really forgot anything, so he was pretty fond on aliens.

Well today was certainly weird. An angel of the lord? How?
"Well.... hi, I'm Sadie," she mumbled, her brow furrowed.
She was confused, her feelings conflicting in her mind. Was she an alien? Was he an alien? Probably, she mused, an angel of the lord? He didn't look much like an angel.
"Can you help me, then? Something weird happened today at school. Someone got me angry at school today, and a storm cloud appeared over my head."
Sadie was still having a hard time believing it herself. She was still wet, she showed her soaked shirt to Cas.
"What does it mean?"
