A/N: I clearly do not own Supernatural or anything related. I do own my character. Except not really…just read it.
He found her at the back of a dingy bar in New Orleans. She kicked her feet against the stool and drummed her dark red nails against the bar. She turned to look at him, the light reflecting off of her dark red hair.
"Didn't think you'd show." Castiel sat next to her as she took a sip of the drink in front of her.
"I had some time. Whiskey?" Castiel asked. "I didn't think you were the type." The girl chuckled.
"A lot's changed since last we spoke Cas," she said. "It's been a long time."
"It has," replied Castiel. "You have been here a long time. Why contact me now?" The girl sighed and sipped her drink again.
"He's told me to find you," she replied. Castiel looked surprised.
"Your boss?" he asked.
"No," she said. "Yours." The look he gave her was one of blank shock.
"You talked to God?" The girl shook her head.
"No, He talked to me."She looked him in the eye for the first time. Though she didn't look any older than nineteen her eyes told a very different story. They looked haunted, scared, and a little pissed off.
"You're hearing the voices again?" Castiel asked. The girl nodded. "How long?"
"Few months." She knocked back the rest of her drink.
"Why didn't you contact me sooner?" The girl laughed.
"Cas, remember what happened the last time you were caught talking to me? I got kicked out. On some crap charge. With the exception of those Winchester boys you've got stashed away somewhere I doubt there's another person on this Earth who hates those angelic sons of bitches more than I do. No offense."
Castiel looked for a moment like he was about to smile, but then seemed to think better of it.
"Does He have a plan?" The girl shrugged. "Can you help us?" She shook her head.
"No more than I'm doing right now. I don't want to bring too much attention to myself. I have a habit of getting burned for doing the right thing." She chuckled.
"Then why are you here?" asked Castiel.
"He wants you to know that you're not alone. You and the brothers aren't the only ones fighting the apocalypse. Your Father can't get involved but others are. My people are organizing." She slapped some cash on the counter and stood up.
"Is that it?" Castiel asked as he followed her toward the door. She turned back to him and smiled sadly.
"It was nice seeing you again, Cas," she said. She reached out and brushed a stray lock of hair back into place. "I like this vessel," she said. "It suits you. Very John Constantine."
"What does that mean?" Castiel asked. She laughed.
"Ask the Winchesters." She turned to leave, but Castiel called out.
"Joan?" Joan turned back, the dim light of the bar reflecting off of a Cross of Lorraine pendant at her throat and an elaborately carved knife at her side.
"Yes?"
"It's nice to know you haven't given up. That you're still fighting." Joan smiled.
"I'm an old soldier, Cas," she replied. "Burn me alive, take away my home, bend me and break me; but if there's evil to be fought I'll be there."
And with that Jeanne d'Arc walked out the door and into the night. Castiel vanished. He had an appointment to get to.
Okay, this may be out of character but it's kind of the prologue to a longer story that's been in my head. I mostly wanted to see how my sort of OC worked on paper. If Cas is OOC I promise he'll get better once I rewatch Season 5.
