Kat eventually joined the boys back at the house; they were saying their goodbyes to Bobby. He turned to her.

"I think me and you should have a little chat half pint" Bobby told her. Dean and Sam exchanged nervous glances.

"Why you want to shot me with a cross bow too?" Her tone was dry.

"So you're not human then?" He nodded. "Though so"

"Oh yeah why's that?" She didn't have time for games and frankly she wasn't in the mood for them either.

"They way you moved, when Meg came crashing through the door you disappeared in seconds ... your beautiful, fast an cranky so I'd say you're a vampire" She nodded.

"Half" She corrected him swiftly.

"Half? What? How?" He was fascinated. A half human half vampire hybrid.

"Don't know, no one does ... I guess I'm a fluke" She frowned.

"Does your daddy know about this?" He looked over to Dean.

"Yeah" Bobby looked shocked.

"So I take it that you and her ..." He gestured to Kat with his head.

"Were together if that's what you mean" Dean wasn't sure he liked where this was going.

"Oh that explains it" Bobby nodded.

"Explains what?" Sam questioned.

"Why John hasn't staked me yet" Kat exchanged a glace with Bobby. "That's what you meant right?"

"... well I err" He shrugged. Kat sighed. Even as they spoke she could still faintly smell Meg's blood.

"That's not gonna happen I'm not gonna let it" Dean told Bobby firmly.

"Neither will I" Kat's words held a dark tone, threatening almost. She loved Dean but she was not going to stand there and let John kill take her out.

"What's the situation with your err eating habits?" Bobby wasn't sure he wanted to know the answer.

"I haven't ... eaten yet" She took a deep breath, all this talk of blood.

"How are you still sane!" Booby raised his eyebrows.

"I've only known that I was ... a vampire for three weeks, I take iron supplements and my own blood combined with them usually sustain me ... but I, if I use my abilities it drains me, makes me week and the supplements aren't helping much"

"Right" He disappeared into the kitchen. "I know I have some somewhere ... just in case ... you know in emergencies ..." He rambled to himself, Dean took Kat's hand.
"Were gonna get through this ... right Sammy"
"Right" Sam smiled at her.

"I'm a liability ... I'm putting you in danger ... even more danger" She smiled weakly.

"We don't care, your family and family's look after each other" Sam told her proudly. "You've never given up on us Kat, this whole mess has nothing to do with you yet your willing to risk your life to help us" He continued. Tears welled in her eyes. She hugged Sam tightly.

"I love you guys" She smiled brightly; she hadn't smiled like that for weeks.

"We love you too Kat and we don't want you to go" Dean kissed her forehead. Bobby appeared with a bag of blood in his hand; Kat jolted, the dark red liquid looked delicious.

"For emergencies" He handed it to her. "It's O positive ... I don't know if you have a preference or ..." She stared at the bag, she felt her fangs pushing through her gums, she restrained herself.

"Thank you" She really needed this, he may not have known it but Bobby had just done her a huge favour.

"Do you think I could put it in the microwave?" The boys looked at her, confusion and amusement on their faces. "What I don't want it cold" They laughed.

"You better hurry up and beat it before the paramedics get here" He smiled at her. She nodded.

"What are you gonna tell them?" Dean asked.

"You think you guys invented lyin' to the cops? I'll figure somethin' out" He handed Kat the book that she and Sam were examining earlier, "Here. Take this. You might need it"

"Thank you Booby, for this, the blood and you know ... not killing me on sight" She smiled.

"You're welcome half pint" He winked,

"Thanks….for everything. Be careful, all right?" Dean nodded at Bobby as they began to move toward the front door.

"You just go find your dad. And when you do, bring him around, would ya? I won't even try to shoot him this time" They all laughed half-heartedly as they left the house.

Kat entered the kitchen area of their current motel room. She examined the bag.

"Dean! Can you come here for a minute please?" He entered the kitchen, wrapping his arms around her waist.

"What is it sweetheart" He ran a trail of kisses up her neck.

"Can you pour some of ... it into a glass and put it in the microwave for me please?" He nodded. "I'd do it myself but I ... If I open that bag I'll probably just gulp it all down in one and I don't want that" She told him. "If I have too much, I'll get stronger, more powerful and I'll crave more ... I don't want that"

"Of course" She walked into the main room taking a seat on the bed. She heard the bag rip, smelt the blood, her fangs dropped. That was the longest minute of her life. Dean placed the cup of blood on the table in front of her. She stared in awe, she looked up at Dean. Slowly she leaned over and picked up the glass. She placed her lips on the edge ... she sipped. Dean watched as her eyes shot open, she gulped down the whole glass instantly. A drop dripped from the side of her mouth, she licked it seductively. Dean gasped, her eyes darted to him. She smiled fangs on display.

"How do you feel?" He choked on his words, he couldn't take his eyes of her. Her own we're deeper, brighter, her skin smother, her hair glossier, her lips fuller. She was perfect. She moved from the bed pinning him against the wall instantly.

"Horney" She smiled seductively.

"Wha – what?" He couldn't think straight, he wanted her ... but John.

"Blood effects libido ... vampire 101" she ran her hand over his thigh. He sighed in pleasure.

"Kat ... baby" She began to kiss his neck, licking, sucking. He couldn't finish his sentence.

"Yes Dean?" She bit her lip. He couldn't resist. He pushed her back onto the bed, their lips crashed, both fighting for control. She gripped his shoulders firmly and rolled him over, she tore his shirt in two and began undoing her jeans. He sat up grabbing her and pulling her close, he pulled her top over her head and threw it onto the floor. Her bra followed. She tugged at his belt removing his jeans and boxers adding them to the pile. Dean pushed Kat forward, gaining superiority pulling her jeans down her legs. She smirked, her fangs glistened, she moaned his name breathlessly as he sucked on the sweet spot on her neck, biting it gently. He removed her underwear, she dug her nails in his back as that familiar feeling began to build in her core. This was different from the first time they had made love... this was raw, primal. They moved in unison, moans filled the room. Their breath became laboured, their movements messy, muscle's tensing as a wave of pleasure engulfed them.

"That was ... amazing" Dean wrapped his arms around Kat as their bodies relaxed.

"Yeah ... I guess there are some plus's to this vamp thing" She opened her mouth and her teeth retracted.

"Oh yeah" He sighed.

"I feel so good" She nuzzled her head into Dean's chest. She could think straight, no pain, no thirst.

"You're not hurting anymore?" He brushed her hair over her ear and kissed her temple.

"Nope far from it" She sighed happily.

"So ... how was it?" His question confused her; she sat up wrapping the quilt around her bare torso.

"The blood or the ... sex?" She blushed.

"... both?" He smirked.

"The blood, the blood was ... good, I needed it so bad ... and the -, it was ..." She sighed, she was a little embarrassed.

"It was ... awesome ... It felt, I can't really explain ... all my senses were heightened so the pleasure was ... it was good okay?" He smirked, very pleased with himself. He put his arms behind his head and sighed.

"Well what can I say?" He nodded. She shook her head. She stood up.

"Where you goin'?" He asked her. She bent down and picked up her clothes

"I'm going for a shower" She told him.

"What no round two?" He raised his eyebrow.

"Well I was goin to ask you to join me in the shower but ... since your a stud I'll leave you too it" She dropped the quilt and winked. He attempted to get out of bed and join her but she slammed the door before he could reach.

"Your such a tease!" He shouted leaning his head on the frame.

"And you love it!" She shouted back.

"I love you!" He smiled.

Sam entered the room just in time to see Dean zipping his jeans up.

"How's Kat is she feeling better?" He placed a huge blue box on the bed.

"Oh yes Sammy boy much better" Dean smiled.

"Yeah ... Dean ... your fly's open" Sam looked away awkwardly.

"Yeah like I said she's a lot better" Dean smirked. Sam shook his head. "Did you have any problems?" He gestured to the box.

"No walked in, flashed the badge, no questions asked" Sam smiled.

"No questions asked about what?" Kat appeared at the door. She noticed the box.

"This" Sam patted it. "It's a present ... for you"

"It's a cooler box ... it's very ... nice ... Thanks Sammy" She wasn't sure where he was going with this.

"No look" He opened it, inside packed to the brim was blood bags. Her fangs dropped. Dean smirked at the memories of last night. She covered her mouth and turned away. She took a deep breath and they retracted.

"I got all different types cause I wasn't sure what flavour you preferred" He smiled shutting the lid.

"I err ... thanks Sammy" She attempted to smile.

"You don't like it?" He frowned.

"No no it's just ... the way you talk about makes it seem so ... normal, like we're talking about my favourite ice cream flavour" She scoffed.

"Well ... none of us are exactly normal sweetheart" Dean winked at her.

"True" She smiled. "Thank you Sammy" She hugged him tightly.

"Oh I got you this too" He pulled out a flask with smiley faces all over it.

"Right" She took it from him and examined it.

"Yeah cause I thought that you could put your blood in and then put it in the microwave or whatever and then it would keep warm when were on the road" He smiled brightly.

"Thanks" She was a bit over whelmed. "I am so grateful I am but ... I don't know it's still a bit ... strange ..."

"Kat it's what you need and so were gonna make sure you get it" Dean smiled.

"Right I'm gonna go warm up some O and then we can get going" She giggled to herself. "Maybe I could draw tiny fangs on the smiley faces?"
