"Ahh."Kate hissed suddenly and turned over her left arm. The sleeve of her only dress suit was sliced open and bloody. She winced and pulled off her blazer gingerly. "Great." She groaned. The left sleeve was spotted with blood and the back had a smear of blood in a handprint shape.

She looked at the skin of her left arm where a small gash cut into the skin. It was a tiny cut worth nothing more than a band-aid but it burned. The blood under her skin felt as if it were on fire and it was spreading both down into her fingers and up into her shoulder. "What the Hell?" She hissed in pain.

"What's wrong?" Sam asked in a concerned voice, pausing from pouring gasoline all over the floorboards.

"Nothing it's just," She gasped, "Ahh, my arm." She held it away from her side tensely, her fingers shaking from the effort. She could feel sweat building on the back of her neck.

Dean came up from behind her and grabbed her upper arm and she groaned in pain. "What are you complaining about?" He asked. He looked closely at her arm, "What this?" He pointed in disbelief, "This is a paper cut."

She felt the burning heat consume her chest and she gasped for air. As soon as the heat hit her heart she swayed into Dean. "Oh God." Kate moaned and tears formed in eyes. Dean caught her with a confused glance at Sam who started to splash the gas as quickly as he could.

"Sam!" Dean called over his shoulder as he swept his sister into his arms. "Finish up here, I'm getting her back to the motel."

"Yeah." Sam agreed throwing the empty can into the corner and picking up the next.

Dean pushed the door open, "You call me as soon as your done." Sam nodded.

He set Kate in the passenger seat of the impala with a frown. She couldn't think clearly, all she could feel was pain.

She didn't even notice when the car stopped and Dean carried her inside. He used a damp wash cloth to wipe the sweat off her face and left it on her forehead. Frowning in worry he took his phone and went outside to call Sam.

"Kalliel." a voice called to her.

She didn't answer but her unconscious self could here the voice.

"Kalliel" It called again, "Answer me daughter."

She forced herself to form a weak reply. "Yes?"

"You must listen to me." The voice she recognized as Castiel's said urgently. "You have demon sickness."

"What?" She asked. In her unconscious sate she could feel the pain but it was distant, almost as if her mind was shielding her from the fire.

"The cut on your arm," He said impatiently, "Demon blood got inside. Whatever you do don't try to heal yourself, it will only make the pain worse."

"Cas!" She yelled as she felt him start to pull away, "Then what am I supposed to do?"

"Wait for it to pass." He said calmly and she felt him fade away.

She could feel the fire raging again with a vengeance. She pushed the damp cloth off her face and squinted around the room. Dean was nowhere to be found. Kate groaned and closed her eyes and was asleep again.

A cold wet rag was dabbing at her face and neck when she woke up. "What the hell is this?" Sam's voice muttered.

"Demon sickness." She groaned not opening her eyes.

A drop of cold water landed on her eyelid when Sam jerked his wrist in surprise. His breath exited his lungs with a loud sigh of relief. "God, you're awake."

She cracked open an eye only to shut it hastily as the light from the lamp made her head throb. "Wish I wasn't" She groaned wryly.

Sam chuckled and she heard the door open and shut quietly. "She's awake." Sam said quietly to someone she assumed was Dean.

"Good, another hour and I would have called an ambulance. Saves me money." He said in a gruff voice but she could tell he was relieved.

"Your hilarious." She groaned. She tried again to let her eyes adjust to the light and was rewarded with a stab of pain in her head. "Lights, Sam."

The heat from the light disappeared and she slowly opened her eyes again. "Remind me to stay away from demon blood."

"That's what did this?" Dean asked her.

She nodded slightly. "The Angel blood reacted to it like a virus."

Sam frowned at the new information. "How do we make you get better?"

"Runes?" Dean asked before she could answer Sam.

Wincing she said. "Nothing, Cas said to let it run its course." Her eyes widened as she felt her head grow dizzy. "Ugh Sam." She choked.

"Yeah?"

She held her hand to her mouth. "I think I need a bucket." Her stomach rolled as a wave of nausea hit.

"Oh." Sam jumped up and ran into the bathroom.

Dean grimaced, "Yugh."

Sam handed her the bucket just in time as she heaved into it.

"That's nasty." Dean muttered. Kate raised her head to glare at him, her skin shining with a sheen of sweat.

Sam handed her a washcloth to wipe her face and took one of the rubberbands off of her wrist. He motioned for her to turn her head and he pulled her hair into a messy ponytail. Suddenly she snatched the bucket back again and dry heaved. She whimpered and glanced desperately at her brother. "I'm sorry squirt." He murmured.

"It'll pass." She whispered. "it has to pass."

Sam nodded and went over to her bag and pulled out a pair of sleep shorts and a tank top. "These fine?"

She nodded and sat up slowly she glanced pointedly at her brothers. Getting the hint Dean grabbed Sam by the arm and they both went outside.

After she changed she laid back down, Sam poked his head in the door. "You decent."

"Yeah" She said back

He came back in followed by Dean.

"I'm going to try to sleep Sam." She said and walked over and kissed her forehead.

"Get some rest."

When she woke up it was morning and Sam and Dean were already sifting through newspapers and news reports. She made a grunting noise in the back of her throat. Dean's head snapped up and he grinned, "Still feel like shit?"

She made a face at him and sat up cautiously. "I feel pretty good."

"Good." Dean smiled. "I wanna get out of here before the cops come knocking."

She nodded understandingly and threw off the covers. She stood slowly, testing her stomach. Satisfied that she was fine Kate walked to Dean and looked over his shoulder at the papers in his hands. "Anything good?"

Sam snorted, "By good you mean death and carnage?"

"Yeah." She admitted matter-a-factly.

Shaking his head he answered her question. "In Minnesota six bodies have been found with the hearts missing, cops are thinking a sadistic serial killer."

She narrowed her eyes, "*TOD's match with the lunar cycle?"

"Yeah, two for each night before and after the full moon." He handed her the stack of papers in his hand. She sifted through them as he talked. "It's targeting couples. Now these newspapers say the deaths happened three weeks ago and nothing has happened since." He pointed to catch her attention. "Now get this, the same MO has been happening every few months for the last three years. Local Leos just called in the BAU* to help them catch the 'heart breaker'." he put air quotes around the name.

She pursed her lips thoughtfully, "Sounds pretty cut and dry to me." She shrugged her shoulders. "We take our time getting there then we start trying to find the son of a bitch."

"You make it sound fun." Dean said with a surprised tone.

She frowned, "Don't get me wrong, it really sucks that we have to kill someone who is completely normal most of the month, but the beast inside them is killing people." She looked at them with wide eyes. "Our job is to save people to protect them, which means we some times have to kill. No one ever said being a hunter was easy."

Sam nodded unhappily and Dean just stared at the wall.

"If anybody should be opposed to killing people its me," Kate said. "I'm the one whose part angel."

Trying to break the tension in the room Dean clapped his hands together, "Who wants breakfast."

Sam and Kate both grinned and raised their hands.

Dean laughed at them, "Get dressed kid, and make it quick I'm starved."


I admit this Chapter is not some of my best work, it took me forever to get through it.

Sorry it's been so long! I just finished a travel ball season so I should be posting chapters a lot faster now! I'll try to get another one up tomorrow!
