Jael went into the bathroom to make adjustments, leaving Sam with the photo of John Winchester and some woman. "Dean," he said. "Come take a look at this."

"Is that- Dad?" Dean asked incredulously.

"Yup," said Sam. "And get this; she says that that's her father."

"What?"

"Well there was Adam... I guess it's possible." He shrugged.

"So we have a sister?" Dean blinked in disbelief.

"Half-sister, yes."

"She could be lying."

"We can't exactly get blood tests." Seeing as we're wanted or dead in most states. was the unspoken reason.

"Do you think that- maybe Cas could check?" Sam gave him a why-don't-you-ask-him look. Dean sighed and began to pray. "Castiel we pray that you're listening because well... we may have a sister."

"I'm here."

Jael took off Sam's shirt and gaped at herself in the mirror. She was covered in small scratches, with one particularly big gash on her forehead. That gash appeared to have been stitched up with- was that dental floss? What the hell happened? she thought.

Ick. There was blood on her bra. She'd need a new one. Still she set to work on Sam's shirt, making it into a romper, because dresses are inconvenient.

She went through her bag and did a check list. Sweatshirt, iPod, cash, spare products, Swiss Army Knife, books... Everything was accounted for accept her damn phone. Of course. Just my luck.

She walked back into the main room, where Sam, Dean, and another man were standing around in. The other man had dark hair and blue eyes that were almost always on Dean in an adoring way.

"Is this her?" asked Dean's Boyfriend in a surprisingly gruff voice. For a man who looked like a puppy, he had the voice of a full-grown mastiff.

"Yes," said Dean.

"Who's this?" asked Jael. "Another cosplayer? I don't remember any guys in overcoats in the books."

"I am Castiel. I'm an Angel of The Lord."

"Okay, my name is Jael Carson. I was named after an angel, at least the first name, seeing as angels don't have last names."

"How old are you, Jael?"

"You know, it's rude to ask a woman how old she is," she joked.

Cas turned to Dean. "You did not inform me of this."

"Cas, not now," said Dean, sounding like a stern wife.

"Right, sorry." He put his attention back on Jael.

"I'm 15," she answered.

"What were your parents names?"

"Emily Carson and John Winchester," she asserted.

Castiel squinted, cocked his head to the side, and then vanished.

A second later he reappeared on the other side of the room. "She's your sister."

"Are you sure?" inquired Sam.

Cas gave him a look that the Winchesters were very familiar with, it was a cross between annoyance and confirmation.

"Wait, what?" Jael was confused.

Sam sighed and looked down at her. "Our father's name was John Winchester."

"I have brothers?" She took a moment to absorb this information, then hugged Sam. "Awesome!" She pulled back. "Hold on, you said your father's name was John Winchester."

"He's dead," said Dean, matter-of-factly, but a note of sadness was evident in his tone.

Jael went and hugged him, which was rather a surprise for him. "I'm sorry. I'm sure he was a great man." Standing back, she said,"How lucky am I? Kidnapped by my own two brothers, even if they are crazy-obsessed with a book series." The small girl yawned and sat down on one of the beds. "Well my head still hurts, so I'm going to hit the hay. G'night." The second her head hit the pillow, she was out.

Sam, Dean, and Cas just stared at the sleeping little thing in disbelief.

"A sister? Who's 15?" Dean ran a hand through his hair. "I mean, if she was an adult it would be no problem, but what are we supposed to do with a 15-year-old girl?"

Sam shrugged. "Maybe she has other family?" He opened his lap top and searched Jael.

The first thing that popped up was an article that read; "Missing Child- Jael Carson". Sam opened it. "It says here that Jael's mother died recently, and she was set to go into the foster system, but then she disappeared. Apparently she sold her mom's car for cash and has been seen all around the country since. The latest report is from Lawrence, Kansas."

"Which is where we found her," finished Dean.

"Exactly. Which means someone called her in recently, so the search is still on."

"So what do we do? We can't just leave her."

"Why not?" chimed in Castiel. "You left Adam in Hell."

"Shut up." Dean glared at Cas. "That's exactly why we can't leave her."

"We could... Adopt her?" suggested Sam.

"That's going to take a lot of work."

"I know someone who can give us enough information to pass a background check."

"But how?"

"You need to be married to adopt, so..." Sam trailed off, not sure where to go with that sentence.

"Cas and I could do it."

"I guess I'll shoot him an email." Sam resumed typing.

"Hey Cas, did you hear that?" Dean turned around to see Castiel staring at Jael, who was spasming wildly.

"Jael!" he yelled.
