Castiel felt a heavy tug at his grace and he immediately took off. He roamed, homing in on a small town in Texas when he realised that he vaguely recognised whoever was calling at him. Landing at the opening of an alley, the angel could just make out a figure lying at the end of the road. Cautiously, he started moving towards them, worry growing as he noticed the sheer amount of blood pooling on the floor. The figure he realised was a teenage girl, no older than 16 or 17, bloody and bruised and left with an angel blade embedded in her chest. Castiel didn't understand how the girl was breathing, let alone conscious. To the side of her, slumped against the wall, was a body with burnt out eyes- he didn't need to look at it long to figure out it was a recently smited demon. She was clearly terrified but Cas managed to reassure her enough to approach the young human. Cradling her face, the angel quickly assessed the girl as her eyes rolled back into her head. Thinking that he could do more to help at the Winchester's bunker, Castiel scooped the abused teenager into his arms and took off.
Arriving in the brightly lit main room of the bunker, Castiel was met by two confussed and slightly pissed faces. "Cas, what the hell?" Dean demanded. "You don't just fly off mid conversation…"
"I apologise Dean but I had more pressing issues to deal with," Cas interrupted with a growl, nodding to the unconscious form in his arms.
"What the hell happened?" Sam started but the angel once again cut him off.
"Can I use one of the bedrooms?" Castiel asked, striding forward without waiting for a reply.
"Yeah of course. You can use mine," the younger Winchester replied, knowing how protective Dean was of his own room. Cas entered the room and gently lowered the injured girl on to the immaculately made bed. The two brothers loitered in the doorway, looking on from afar and giving him some pace. They could tell he was worried. Wrapping his hand around the blade, he yanked it from the teen's chest and immediately rested his free hand on the girl's forehead, pouring his grace into her. Castiel healed what he could. He repaired the gapping holes left by the blade, he knitted bones back together and fussed her skull back into place, removing the swelling to her brain as he did so. The only thing he couldn't mend were the delicate cuts that formed symbols over her skin. Every time Castile's grace went near it, some force deflected it. Cas felt his stomach drop. He knew the only way he could heal her but it would be almost unbearable for her. Stroking the hair from her face, Castiel came to the realisation that for some unknown reason, he really cared for the young human.
Exiting the bedroom, Castiel went to join the brothers who were sat at the table in the other room. "How is she?" Sam asked, noticing the angel coming to join them.
"Better, I think. I've healed as much as I can." Cas replied, looking tired.
"As much as you can?" Dean questioned.
"It seems that whatever happened to her involved carving symbols on to her skin, but they have been tainted so my grace can't heal them. The only way I can fix it is if she's conscious and gives me permission- I need to access her soul to give me the extra power.
"Won't that be painful?" the younger Winchester asked. Cas simply nodded.
"What exactly did happen Cas?" It was Dean who addressed him.
"I… I don't know," Castiel admitted. "Most likely a demon attack- the wounds were tainted with the reek of hell. I just don't understand how she survived at all with that much damage."
"Well there's one way to find out. We wake her up and talk to her," Dean interjected.
"No Dean!" Cas barked. "She needs to rest." The brothers shared a look but seemed to accept what the angel said. "There's something else. Beside the girl there was a demon with its eyes burnt out."
"What, so an angel turned up to smite a demon but left the injured girl to die in her own blood?" Dean asked sceptically.
"Maybe said angel only had enough juice to kill the demon and prevent her from dying without actually healing the wounds?" Sam theorised. The two Winchesters both looked at Cas for a response.
"No I would have felt another angel's grace if that had been the case. Except…" He was met with narrowed eyed stairs. Cas signed. "One of the reasons I took off so quickly was because something about the call felt familiar, but I didn't know who it was or understand why it did." Before either of the boys could respond Castiel muttered something about checking on the teenager and walked of in the direction of Sam's bedroom.
"Well something's definitely ruffled his feathers," Dean stated as soon as the angle was out of earshot.
