Last time in "Situational Control":

"I can't leave you. What if Goodwin is wrong?" The others began breaking through the door almost completely, one of them even putting his leg through and ducking until he stepped into the store.

"He isn't, trust me."

"Rick, I..." The doors shattered and the wave of them began staggering into the store and quickly moving towards them. Rick popped off a few rounds, some of them dropping to the ground, before he turned to her, his eyes flaming.

"KATE, DAMN IT, RUN!"

Kate bolted up the stairs, her lungs feeling like they were on fire as adrenaline coarsed through her. She had left him, and she couldn't even fathom the fact that he could be killed. She leaned forward and leaned her hands on her knees, gasping to try to suck in deep breaths.

"Where is he, Kate?" Goodwin asked, glancing from her to the door and back.

"He...he made me leave him...he's fighting them." She gasped, no longer out of breath from exhertion so much as anxiety that clawed at every fiber of her being.

"What? He's down there by himself?" Ryan snapped, pulling his gun from his holster and moving towards the door.

"Ryan, he said that we are supposed to stay up here!" Kate called after him as he flung the door open and started down the stairs. She sighed loudly and moved to follow him, her own gun drawn.

"The hell we are! He isn't going to die down there because he was too damned stubborn to accept our help." Ryan mumbled. They stormed down the stairs and saw Rick standing in the middle of a large group of them, his combat knife glinting in the dim light as he moved fluidly.

Kate began shooting, careful to aim for their heads and avoid Rick's. The bodies dropped in a spray of black, tarry coffin liquor as the bullets tore through them. Rick plunged his knife deeply into one of their eye sockets, giving the blade a quick turn before sliding it out of the rotted flesh.

Ryan's gun flashed as he fired round after round into them, the sick, wet thwack as they hit the bodies triggered a slight twitch in the back of Kate's mind. Her stomach churned and she leaned over the railing, emptying the contents of her stomach. When she stablized herself enough and was sure that she was not going to be sick again, she straightened and turned back to were Rick stood, his chest heaving as he surveyed the pile of bodies around him.

"I thought I told you to stay upstairs?"

"And let you have all of the fun? No way." Ryan smirked and hosltered his gun once again. They motioned for the others that had stayed on the roof to come down.

"Now where do we go?" Kate asked, her voice shaky and the lingering taste of vomit on the back of her tongue. She reached into her backpack and pulled a bottle of water, swishing it through her mouth quickly before spitting it over the railing.

"We need to move to another building. Set up camp, see what other supplies that we can gather, and mark out what our next plan is going to be." Castle motioned for everyone to gather their packs. "We need to move quickly, and quietly. They are attracted to noise and we can't draw attention to ourselves."

The gang hoisted their packs and grabbed as many supplies as they could. They moved slowly and quietly to the door, all of their senses on high alert. The streets were abandoned and empty, but they were hung with an ominous, moonlit glow. They moved slowly and silently through the rows of cars until they rounded the next block and noticed a darkened hotel. It wasn't large, especially for being in the middle of New York City, but it would be perfect.

The door was open when Castle tried pushing it inward. They split up and checked every one of the rooms for others, but found that they were alone. They met up in the lobby and boarded up the doors.

"Okay, you guys can stay here while I move out to scout the area."

"Shouldn't you wait until the sun comes up?" Esposito asked, bending to dig through the bag at his feet until he found a bottle of water.

"I can see, remember? I track by heat signatures and scent. Everything gives off some sort of signature, so I can see everything at night." He mumbled, his mouth watering as he watched the other man's Adam's apple bob as he drank the water. His tongue suddenly felt too thick for his mouth and a deep ache curled in the pit of his stomach. He yearned to have the heavy metallic taste of blood running down the back of his throat.

He felt sweat trickling down the back of his neck, and suddenly the room was too crowded. The whirring of white noise in his brain suddenly seemed like it was a hundred times louder than it had been a moment before. It vaugely resgistered that Kate was saying something to him, but he couldn't focus long enough to figure out what it was. It took him a moment before he was able to break through the haze in his mind.

"Rick? Are you okay?" She mumbled, her hand on his arm was scorching hot against his cold skin. He opened his mouth to respond, but opted for running to the closest room instead, slamming the door behind him. His chest heaved as he sat on the edge of the bed, his head resting in his hands. He couldn't even fathom the fact that he'd had thoughts like that about Espostio.

Since he'd turned, he noticed more and more frequently that his thoughts seemed like they weren't his own. They were animalistic, vicious and frightening. He'd had been trying to force himself to breathe, even though the need was no longer there. He missed the normalcy, and the unformed intake of breath every few seconds. He missed sleeping. He hadn't needed to sleep more than an hour since the change.

He heard the click of her shoes long before she opened the door and poked her head in.

"Rick?" She whispered, stepping cautiously into the room and closing the door gently behind her. He heard the 'click' of the lock and winced. She was locked in the room with him. He was a monster, and she locked the damned door...

"Please leave, Kate." His voice was low and even as he spoke. He was getting damned good at hiding the quiver of fear that he was feeling.

"Good luck with that." She chuckled, sitting next to him on the bed. She hooked her finger under his chin and lifted his head so that she could look in his eyes. "Talk to me."

"I...Espostio." He stated.

"What about him?"

"He...I was thinking about..." He heaved a sigh and shook his head. "Nothing."

"That look wasn't nothing. You ran out like you'd seen a ghost, Rick."

"I was thinking about killing him, okay?" He barked, watching the pulse in her neck speed up in fear as he growled the words at her. Before he had a chance to stop himself, he had her pinned to the bed, his body settled between her legs and his hands holding hers above her head.

Kate gasped when she felt a hard throbbing against her thigh, the evidence of his arousal shocking the both of them. His forced breath was hot and rough against her face as his eyes burned into hers. His hips thrusted forward against hers of their own volition. A deep, gravely groan emitted from her throat and her eyes fluttered shut.

He knew he should stop, but that didn't stop him from grasping her breast roughly in his calloused hand as he pulled into a bruising kiss. He pinched her hardened nipple through the fabric of her shirt and rolled it roughly. Kate groaned again, the noises she was making only spurring him on further.

He leaned back enough to slip out of his jeans and boxers, his raging erection throbbing almost painfully. He wondered for a moment, how that was even possible when there was no blood pumping through his veins, but the thought was lost amidst the lust that seared through him.

He reached forward and tore her clothing from her body, his eyes raking hungrily over her frame. He felt like he was seeing her body for the first time again. He tore his shirt over his head and tossed it across the room before hovering over her, his chest barely brushing over her taught nipples, just enough to create a delicious friction between them. His tip brushed her entrance, her wetness coating the tip heatedly. He had never known a warmth like that, when her hot center brushed over his icy skin.

His kissed her neck hungrily, teeth grazing vulnerable skin violently enough to leave purple-red bruises on the ivory canvas. He was so close to breaking skin. Close enough to taste the blood running underneath the close knit skin cells. He nipped the hollow of her throat and used the arching of her back, which he knew had been coming when he found that spot, and slid into her heat until he was buried to the hilt.

They let out a collective sigh of contentment as he began thrusting frantically, not giving her a chance to adjust to his overwhelming size. He let his cool fingers drift down her torso as they moved together, the diffence in heat making her shiver, until he reached the overly sensitive bundle of nerves seated in her dripping womanhood. He rubbed small circles on the bundle until she was writhing beneath him, her muscles clenching around him. She was so close, he could feel her orgasm building under the surface, but he wasn't finished with her yet. He leaned down until his mouth was directly next to her ear and pulled completely out of her. Her whine of protest almost had him pounding into her once again.

"You do not come until I tell you. Are we clear?" He snarled against the shell of her ear. She couldn't answer him, so she opted to nod slowly. He allowed himself to slip back inside her and kept his thrusts slow and methodic, drawing mewls and sighs from her that he'd never heard any woman make before.

"Please, God, harder!" She hissed, throwing her hips up towards him. Rick couldn't deny her, but he also felt heat curling in his stomach. His hips started moving viciously, pounding against hers until the only sounds that filled the room was the slap of their skin against one another and her harsh, ragged breathing. "Ah...Rick...I'm going to c-come..." She stammered. "P-please, don't stop." She moaned loudly, her fingers grasping at his shoulders and pulling him into another rough kiss. He felt her shatter around him, her muscles quivering around him and pulling his own release from deep within him.

He groaned loudly, his heated release filling her in a way that she'd never experienced. He hovered above her a moment, his head buried in the crook of her neck as he waited to regain his bearings and for the room to stop spinning around him before he rolled onto his back, slipping out of her but holding her to his chest. He pulled the wrinkled comforter over their naked bodies, his still icy cold, but hers heated with the startchy feel of drying sweat.

"I'm sorry." He whispered into her ear, guilt and shame boiling inside him like an illness.

"Don't be, Rick. I know this is hard for you." She replied, turning her face up to look at him and resting her chin on his chest. "You're not really going to go out there after those things in the dark by yourself are you?"

"How else are we going to know what we're dealing with? And I would rather have me out there than any of you. I'll hear them, smell them, and get their heat signature way before you would."

"Do they even have a heat signature?" She ran a hand over his stomach, shivering at the coolness of his skin. "You're so cold."

"Everything has a heat signature, Kate, some are just hotter than others." He chuckled, tracing the curve of her hip. She gave a large yawn in response. "You need some sleep." He murmured against her hair.

"I know..." She replied, her breath slowing even as she spoke. He stroked her hair for a moment, his fingers tangling around the silken locks until she fell asleep. He seized the moment of her sleeping and slid his arm out from around her, and shuffled around quietly until he was dressed.

He slipped his shoes on and hooked his belt before moving towards the door, making sure that his gun was cocked and ready. He hesitated a moment, his hand clasping the door and he banged his head against the frame lightly. He sighed and glanced at her sleeping figure.

"I love you, Katherine Beckett." He whispered and moved out into the lobby to go scout the area. She desperately wished that he had stayed to hear her whisper her response.

"I love you too."
