The Fallen Angel

Disclaimer: I don't own Harry Potter or Supernatural. If I did Harry would be with Castiel and Gabriel. Too bad. Well on with the story. Oneshot.

3rd Person

For all their extended knowledge, the angels were far from being omniscient, sure they knew a lot of things men couldn't even begin to understand but it didn't mean they knew everything there was to know about the universe. They were still learning. Zachariah prided himself for his own knowledge but he did accept the fact that there were some things even angels could not understand sometimes.

There was one thing the six-winged angel could not stand though and it was when unknown entities suddenly stood in the way of the Great Plan.

Helena Potter, now known as Helena Evans, was one of these entities. A witch turned hunter for no apparent reasons at all. As far as he could recall, magic wielders had always tended to stay as far away as they could from the hunters' world, it was mainly why the American Wizarding community was so small compared to the European's. Potter, on the contrary, seemed quite determined to defy all these known laws. Such a peculiar creature.

Zachariah couldn't let him ruin their plan however.

It was mainly the reason why he was now spying on the oblivious witch from afar. The hunter had apparently decided to return to the warehouse where Castiel had disappeared. Zachariah watched as Evans crouched by the spot he remembered they had trapped Castiel within. He had to lean slightly to hear her quietly mutter under her breath "Holy oil". Sure the angels had indeed used the oil to contain the rebellious angel but there was no way the witch could have known what the apparent smudge on the floor was unless... now that was an interesting thought, he pondered.

"Impressive," the angel revealed himself, noticing the other's surprise with a smug smile.

The startled look quickly turned into a blank face though, much to his own disappointment.

"I find it impressive how a mere witch could know such things when we, angels, haven't been on Earth for more than two millennia."

The witch stayed silent.

"But then again, you aren't just a mere witch, are you?"

He almost missed the slight tension in the other's shoulders as he slowly walked towards her and smiled inwardly. There. He was finally going somewhere.

"I only did my lessons about you guys," the green-eyed hunter shrugged off nonchalantly. "One can never be too careful."

The witch wasn't stupid, Zachariah had to admit it. Instead of being annoyed by that fact, he smirked to himself. It made things all the more interesting. Evans didn't know who she was playing with although.

"Quite right," he agreed easily.

Much to his disappointment again, no emotions seem to cross the other's face. Zachariah had at least expected some relief when he didn't stress on the subject of her true identity. The angel could have almost took her for one of his kind with the way she was holding tightly her emotions. No human could perform such feat at this rate.

The raven-haired woman surely had a weakness though and he was going to find it. Be it by force or cleverness.

He then noticed the witch staring intently at the unfinished Banishing Sigil on the wall, her face still unreadable.

"Castiel overstepped his boundaries, he had to be punished."

"You know, Zachariah." Helena said (Leaving the angel to wonder how she knew his name), while tracing her fingers over the unfinished Angel Banishing Sigil, using the small bleeding cut on her finger to finish it. She turned round to face the other angel, making sure to block the now finished Sigil. "You really shouldn't have come near me when you know that I am more than just a witch."

"Why, afraid of showing who you are?" Zachariah sneered.

"Of course not. I just don't want to die." She said with a small laugh.

"Then what are you?" Zachariah asked, now a little curious, not noticing that the Banishing Sigil was finished until Evans put her hand on it.

"A Fallen, one you should know of, seeing as I used to be our Lord's messenger."

"…Sophiel.(1)" Zachariah breathed, not believing that the Fallen Angel was alive.

"Yes, indeed. Goodbye Zachariah." And with that Helena pushed what she thought was magic (but was really what she had left over from her Grace, which had disguised itself as magic) into the Enochian symbol behind her and banished Zachariah from the Warehouse where the Angels had taken Castiel from.

One Week Later

3rd Person

"You know, you really should not have told Zachariah who you really were, Sophiel." A voice said in Helena's bedroom.

"Cas. You're alright." Helena said, leaping up and jumping at the angel. "I thought you were trapped in Heaven." continued Helena after Castiel had caught her mid-jump and hugged her close.

"I'm fine, Sophiel." Castiel said after the Fallen angel had calmed down. Castiel tilted Sophiel's face upwards and kissed her lightly to show that he was real. "And I won't be leaving." Castiel finished just as Sophiel deepened the kiss. Castiel moaned and Sophiel moved her hands from Castiel's shoulders and tangled them in the others hair. Castiel carried Sophiel to the bedroom where they spent several hours sleeping and doing other…things that a normal angel wouldn't really do.

A/N Tell me how you like it. Constructive criticism appreciated.

1: This was a name I liked from another Supernatural Harry Potter crossover. I needed a female name appropriate for an angel and that seemed to fit.
