Dean and Sam took shifts watching over Bailey, as she slept in the fetal position. Both jumping to her side, when she whimpered in her sleep, or shifted like she was waking up, but she didn't wake up.

Three days later, it was Dean's turn to watch her again while Sam slept... finally. Sam had been taking overly long shifts, so that Dean would sleep instead of smoke.

Dean waited until Sam was asleep, or he thought he was, and started talking to Bailey as she slept. "I need you to wake up, Bailey. I didn't realize it, but in the last couple days you became important to us... to me. I know I didn't show it by getting mad, before you were stabbed, and if you wake up, I promise to make it up to you. Just please wake up, Bailey." He found himself pleading, and praying that Cas or God do something to help the girl.

Cas appeared in a flutter of wings, earning a two guns facing him. "You're both jumpy..." he commented, skipping his usual 'hello, dean'.

"An angel appeared, said Bailey was powerful, stabbed Bailey horribly, and then she healed herself and melted silver. Cas, what is she?" Sam asked, with a yawn, as he had yet to sleep.

"You said she melted the angel blade with her blood?" Cas asked, frowning deeply in thought.

"Yes, my blood made the silver burn me." Bailey said weakly, sitting up rapidly to look at the two men and an angel before her.

"BAILEY!" Sam and Dean yelled at the same time, earning a weak smile from her. If asked, she would admit she was exhausted and felt like she had gone 30 rounds with King Kong. Her body ached, like she was one massive bruise.

"Are you okay?" Dean asked in a rush, moving to touch her arm.

"Don't!" Bailey yelled a second too late, as her skin zapped his hand with an electrical shock that found him across the room and buried in a wall.

"What the...?" Dean asked in a strangled and pained voice, too stunned to know what else to say.

"I tried to warn you... I think my body absorbed the power from the angel blade, and it made my skin electrical or like static filled." Bailey explained, her voice sounding more exhausted than before.

"Stop touching her, you are draining her energy, essentially her life force is too weak to withstand the turmoil she has endured. I won't hurt you, so don't zap me." Cas said calmly, approaching her slowly. He reached out, touching her forehead lightly and frowning, noticing immediately that her skin was vibrating with power.

"Am i hurting you?" Bailey asked, noticing his frown. She could feel the vibrations, but didn't know how to stop them or turn them off, or what she could do. The more she thought on it, the more intense the vibration became, until it had Cas vibrating too.

Cas whipped his hand away from her, shaking it aggressively to get rid of the vibration. "No, you didn't harm me... how is it possible for a car to become human? And how did you get angel in you? Much less... is it angel or something else?" He asked aloud.

Sam and Dean's eyes widened at all of Cas' questions, as Sam helped Dean out of the crumbling wall.

"Wait, so she is an angel?" Dean asked, sounding sore and in pain. He moved gingerly to a chair, moving like an elderly person, as everything hurt.

"No... But she does have angel grace in her blood." Cas said cryptically, as his frown deepened.

Bailey flinched, as her eyes blazed an electric red and silver. "That's not exactly helpful, feathers." she grumbled angrily, the more annoyed she got the brighter her eyes got.

"Calm down, Bailey. We have no idea what you are... that doesn't mean anything bad. It just means you're a mystery, that we can figure out." Sam said, a hint of authority in his tone.

Bailey glared at Sam, annoyance marring her otherwise beautiful features. "And what happens if I am something bad? What then?! No offense, but I don't need you and Dean looking at me like I am a monster." she said headily, all agitation leaking away from her as her face showed only anxiety.

"I can't promise that won't happen, but i can promise, we won't abandon you." Dean spoke up firmly, promising what he should have promised Sam all those years ago.

Sam flinched, flashing back to his own story. "I agree with Dean." he said, making his own promise to her.

Bailey nodded, the electricity vanishing from her skin. "I am not dangerous to touch anymore." she said, touching Cas' hand lightly.

"She is correct, you can touch her now." Cas agreed, before disappearing in a flutter of wings.

"Why does he do that?" Bailey asked curiously, as she gingerly stood up and wrapped an arm protectively around her ribs and where she was stabbed. "Ow..." she mumbled painfully.

Sam moved quickly to her side, guiding her to the couch Dean was sitting on. "Take it easy..." he said gently, as there was a honked horn outside. "I called Garth about a car, that's him." he said with a chuckle.

He walked outside to see Garth driving away, leaving a car where Bailey had been found. He grabbed the keys, taped inside the visor of the driver's seat. He walked back inside after locking the car, put the keys on the table, and walked back over to Dean and Bailey.

"All good?" Dean asked, knowing they needed to get Bailey back to the bunker, but needed a working car to get there.

Sam chuckled and nodded. "Yeah, we're all good. Whenever you want to head out, we can. Bailey, are you ready to see what its like to be in a car that you ride in?" he asked, not receiving an answer. "Uh, bailey?" he asked, looking over to see that she had fallen asleep on the couch, her head on Dean's lap.

Dean lightly ran his fingers through her long brown locks, smiling down at her sleepily as he fell asleep himself, head resting back against the couch.

Sam laughed softly, moving to his own bed happily. He made sure to stay alert, but fell into a deep sleep nonetheless.

All three were exhausted, from the emotional and physical rollercoaster of the last few days. Each sleeping deeply, as they felt safe and secure near each other.

Bailey woke up after a couple hours, to see the men were sound asleep. She gingerly got up and walked outside silently, being extra careful not to wake up either of them. "Cas?" she asked the air, hoping he'd answer her.

"You called?" Cas said, appearing silently.

Bailey nodded, and looked back at the angel thoughtfully. "What am I? I know you know." she said simply.

Cas sighed softly. "I actually don't. You have all the abilities of a nephilim, but you aren't one. You were changed by a coven of witches, that gave you so much power, I have no idea what to expect of you." he explained, shaking his head.

She sighed in frustration. "Now what?" she asked finally, after debating for a matter of minutes.

"Protect Sam and Dean... They need the help. Someone from their past is back and extremely dangerous." Cas warned, looking around them. "Go back inside, and get them to go home as soon as they wake up." he said firmly.

Bailey nodded, sensing something dangerous was coming. "Can you get us home?" she asked, knowing the car would be left be left behind.

Cas nodded, snapping his fingers, as all three vanished and reappeared in the bunker. He vanished himself, to investigate the threat.

Bailey looked around for a little bit, before curling back up with Dean on the couch and falling back to sleep.
