Enjoy

Previously:

William laughed and pulled Aaron's hair to expose more of his neck.

"It's nice to finally meet the famous David Rossi."

"Kick the gun over here. If you try and reach for it I will slit his throat." William Reid looked down at the knife and his curled-back lips exposed his teeth in an unpleasant smile. "Do as I say."

Rossi held his hand to his shoulder, trying to stop the blood from his graze and with an angry huff he kicked the gun toward the chair where Aaron sat. It was close to Aaron's foot and the unit chief's eyes flicked down to it momentarily before locking on the knife again.

"Well done," William said sarcastically and he eased the knife off of Aaron's neck. "It seems you can follow direction. I must say I thought you to be much more... hmm, intimidating. The way junior spoke about you, well, I never thought you would submit so easily."

Rossi grit his teeth and squeezed his shoulder in his fury, unconscious to the pain thrumming under his fingers. "You're just as I imagined," Dave spat and with a groan he pulled himself up against the wall some more so he could glare at William properly. The man was chuckling softly as Dave spoke. "You're the same sadistic bastard I imagined." William laughed righteously and Dave narrowed his eyes. "A sick pedophile."

William's laugh cut off suddenly and he glowered back at Dave. He tucked the knife under Aaron's neck, scratching at the stubble there. "I'm not a pedophile," he hissed and he dug the tip of the blade into Aaron's skin which went white from pressure before a thin trickle of blood started to run down his neck. Aaron swallowed thickly, making the knife tremble against his skin.

Dave snorted. "You certainly look like one." He looked at Diana who was still pointing the gun at him and he looked her up and down with a smug smirk. "Doesn't look like your wife satisfies you!"

"Don't!" William held the knife so hard against Aaron's neck that a long line of white skin appeared behind the pressure of the knife.

Dave glanced at Aaron who had squeezed his eyes shut and was mouthing something to himself. "Did I touch a nerve?" Dave asked quietly and he waited for William's breath to even out.

William licked his lips but didn't pull the knife back. "I never touched them," he said hesitantly. "Not in that way."

"What does it matter? You killed those children. You may not have touched them sexually when they were alive but killing them got you off. Your wife didn't do much for you anymore but something about killing those boys got you off, didn't it?"

Diana stared at William with a frown but her gun didn't move away from David.

"You think she had no part in it?" William asked and Dave shrugged, causing shooting pain to go down his arm. He gripped his shoulder more forcefully to staunch the pain.

William laughed then, his smile was back. "Diana picked those boys," he said. "She found the ones she wanted and I would get them... except your boy. She got him herself."

Dave tensed up against the wall. William looked down at Aaron and gently pulled the blade across his neck, leaving an indentation behind.

"Diana found him playing alone because you were busy. And she took him home. I never wanted to take kids that young but Diana said she needed him."

Dave turned to look at Diana who was staring back at him with a cold expression just as unreadable as before.

"So you see, Diana enjoyed it just as much as me. We only kept Spencer because he reminded her of the control she had... but she's been much too attached lately and for this all to work I had to kill him."

Rossi met Aaron's wide eyes: William didn't know Spencer was alive.

"Dont get me wrong," William said, his tone growing wistful. "Having him around was fun. And he was under your nose the whole time!" William breathed in a long, self-righteous breath. "Oh, it felt so good when I had Gideon mentor him. He never knew and then you- oh, well, that was golden."

Dave tried to get up but Diana pointed the gun more fiercely at his head and Aaron made a gruff sound as his hair was pulled back again.

"You son of a bitch!"

William grinned, so damn pleased with himself as he watched David Rossi sink into the floor hopelessly.

"Anyway," William said and he sighed, pulling the knife back a little. "I can't leave this unfinished much longer."

He pulled Aaron's head right back so he was forced to look up at William. "Anything you want to say?"

"This isn't that fun is it," Aaron said in a raspy voice and William's smile fell a little in confusion. Aaron laughed. "Killing me," he added. "Like Rossi said, it doesn't give you the same sexual thrill as little boys."

William looked as if he could lunge forward and rip Aaron's throat with his teeth but even so, Aaron continued to glare at him.

"Do it, William." Diana shifted where she stood, stepping closer to the chair where Aaron sat. "Kill him. I never liked that one..."

"Did you say the same about me?"

Diana turned and was faced with a gun pointed up at her. Spencer didn't adjust his grip, he held the gun steadily at his mother's chest. "Drop it," he said, motioning to the gun in her hand. Diana seemed to fumble with it for a moment, lowering it and then raising it again.

"No," she said, her eyebrows falling sadly.

"No, baby, no! It'll be us... remember? The three of us," she whispered though it sounded more like a question and Spencer nodded slowly.

"Just the three of us," he said, glancing across at William who was holding the knife loosely, his mouth agape. "Just put it down, mom, and we'll sort this out."

Rossi also stared at his son, and the dark, damp patch on his jacket which was suspiciously like the one he'd been wearing earlier. Dave knew in an instant that it was blood. Spencer's hands and face were peeking out from the jacket in stark contrast to its navy shade. He was white, looking a little yellow in the face too. Dave's brows scrunched together in anguish, wishing he could stand up and aid the kid. He adjusted his hand on his own wound and pressed his lips together, preparing himself to jump in front of any bullet Diana sent his son's way.

"Please. Just put it down, mom."

"How..."

Spencer looked to the chair where William stood threateningly over Aaron. He moved his gun from his mother and pointed instead to his 'father.'

"Did you tell mom? Or did you just say I'd run away again?" he said, his voice hard and cold.

William's lips trembled with words he couldn't quite make out as he stared at the young-man he'd been sure he'd murdered a few days prior.

Spencer glanced at his mother who still hadn't put down the gun so he turned his back to her. "She knew," he muttered and he chuckled lightly and shook his head. "Of course she knew."

Diana lifted her gaze and met Spencer's sad eyes. "You were always as bad as him."

"Spencer?"

Spencer's finger shook against the trigger but he kept the gun level as he felt his fiery words bubble to the surface. "There won't be 'the three of us'," he spat, grinding his teeth when he grit them together in determination.

"You promised... baby you said it'd be the three of us."

"I'd rather die than live with you again," Spencer said hoping the words hit his 'mother' with the same hate he felt surging through him.

Diana stared back at the boy she raised, her eyes brimming with tears. She still wasn't dropping the gun. William wasn't easing up on the knife. Spencer narrowed his eyes at them both and kept his gun aimed at Diana.

"How do you think this will play out?" Rossi asked and the sound of his voice had Diana lifting the gun at him again.

"Don't," Spencer said, stepping forward with his gun poised.

"H-he doesn't get to talk," Diana said.

"He's right though. Do you really want to keep doing this with him?"

Diana looked around sharply and glared at Spencer. "He's my husband."

"You don't love him."

"I do."

"We could get you a lesser sentence. You were scared of him, mom. You had nothing to do with it." Spencer let his gun drop a bit and he looked at his mother imploringly.

"I'm not scared of him."

"He's a monster! How can't you see that!?" Spencer motioned to his father incredulously and shook his head. He lifted his gun quickly when William scraped the knife against Aaron's neck.

"Spencer," Aaron started, inhaling suddenly when William pulled his hair and held the knife to his neck. "She helped him. She's just like him."

William dug his fingernails into Aaron's scalp, making the agent groan and successfully silencing him.

Diana took a long deep breath and she pulled her lips into a smile, extending her look of derangement. She flashed the smile at William who grinned back and then she looked at Spencer, her face falling with reprimand.

"I love him," she said again and Spencer realised that she meant every word and every implication those words came with. He shook his head, a suffocating feeling of disappointment consuming him.

Diana fixed him too with an unpleasantly fond smile. "I love you too, baby."

Spencer shook his head slowly and he had to look away from Diana's imploring gaze. "I don't love you. I can't love you."

Diana's smile fell.

"I'm your mother," she said sharply. She motioned over to William with her gun, handling the firearm with steely inexperience. "And he's your father!"

Spencer felt sick with anger and his nose crinkled. "That's my father," he said, looking over at Dave. "David's my dad. And you most certainly aren't my mother."

Diana stared at Spencer. Her eyes were wide, and owlish, her brow arched high above them. She looked at Dave then, her expression falling into an even darker anger and she aimed the gun at his head.

"No!" Spencer's finger hit the trigger and the room exploded with the sound of his gun going off. It was the only gun to go off and, with that knowledge, Spencer squeezed his eyes shut briefly. He heard Diana's body hit the floor and his own arms fell limply to his side. His aim had been true. Square in Diana's chest. She was dead when she hit the ground.

William stared down at his wife, the knife in his hand slipping away from Aaron's neck and dropping to the floor beside them. The whole room was silent with shock. They all stared at Diana who wasn't moving. Blood was starting to fill the space around her, saturating the cream carpet. William broke the tension.

He curled his fists and started toward Spencer.

"You little bastard!" He stomped across the carpet, lunging himself at Spencer before the young man could raise his gun. They both fell to the floor, Spencer helplessly on his back and William straddling him. William smacked the gun away from them and he moved both his hands over Spencer's neck.

Spencer's eyes bloomed in surprise at the sudden cold grasp around his throat and he reached up and hit at William's hands.

"After everything she did for you!"

William squeezed his fingers into Spencer's throat and the young-man wheezed, choking under the strain against his neck.

William grit his teeth together and focused on squeezing as hard as he could. He watched as the boy he raised went red, his lips shaking and turning a dull blue.

"I should've killed you then," William said and he pulled his hands up, bringing Spencer's head with them and shoved him harshly against the ground, his head bouncing with a thud on the carpet.

Spencer couldn't even form words to beg. His vision blurred and started to grow fuzzy at the edges. His fingers tingled and his lungs burned. He gasped up at William as the image of the manic man above started to fade.

Spencer's eyelids fluttered and one of his hands fell from William's arm after one last weak smack. The other arm fell limply to his side and his eyes slid shut.

William held on, his lips wet with spit, and his face scrunched up into a vile mask of rage.

William was resigned not to let go. He was going to hold on until Spencer went cold.

A gunshot rang out through William's angry grunts. William let go of Spencer when a sharp pain split across his shoulder and he yelled out angrily. He tried to stand but the gun went off again, hitting his back with a wet thud. William fell, rolling onto his back beside Spencer and his wife. He gasped when the position irritated the wounds on his back but he couldn't move.

"Spencer!"

Dave, who had been trying and failing to reach Spencer, his shoulder slowing him down, scowled across at William as the man made anguished sounds. He turned to look at Aaron and saw the man was stood up, Rossi's gun in his hand.

He was breathing heavily as he looked at Dave. He gave a short nod and stepped out from the loose rope loops by his feet which he'd struggled with while William had been strangling Spencer and Dave had been trying desperately to get to his feet.

Dave accepted Aaron's hand and heaved himself up, clutching at his shoulder as he tried to keep his legs under him.

Aaron went straight to Spencer.

The young-man hadn't moved yet and as Aaron stumbled to his side and pulled his collar down it was apparent why. Spencer's neck was a frighting shade of red, the places where William has pressed his fingertips were starting to turn purple.

"Spencer?" Aaron shook Spencer, tapping his cheek. When he didn't respond Aaron tapped harder.

Dave finally steadied himself and he staggered over to the Reid's and kicked Diana's gun away. He glanced at her. Her eyes were open a crack, as was her mouth where a thin trail of blood was seeping past her lips. He looked up at William who had started to howl in pain. His eyebrow was hunched in concentration but the rest of his body stayed limp. Dave couldn't help but smirk: one of Aaron's bullets must have hit his spinal cord.

He started over to his son, panic seizing him again when he saw Aaron start chest compressions. Dave quickly leaned against the wall when a woozy feeling overcame him and he forced himself to take deep breaths as he watched helplessly on at Aaron.

"Come on, Spencer," Aaron said, fighting against the pain in his own body as he pressed his palms against Spencer's chest.

Spencer's eyes fluttered open and he coughed painfully. The sound relieved both agents and Aaron helped Spencer turn on his side as he rasped and coughed and wheezed until he was able to pull in a real breath of air.

"Thank god," muttered Aaron and he rubbed a hand up Spencer's back to ease his breathing. Spencer clawed at the carpet as he gulped in huge breaths, saliva dripping from his lips into the cream carpet fibers.

"I'm okay," he whispered, his voice scratchy and tender. "I'm okay."

They barely had a moment to take in the situation when the front door was flung open and heavy footfalls thudded down the hall.

Emily found them first, her gun poised as she stepped into the room filled only by the sound of William's groaning.

"They're here!" Emily dropped her gun and went to Aaron's side, helping him lift Spencer to his feet.

JJ followed quickly and after gazing around the room with a look of horror, she hurried over to Dave and helped his support himself.

"So this is where you went?" she said, her voice scolding. "I thought you were gonna start telling us things."

Dave flashed her a pained smile. "Sorry."

JJ smiled reluctantly and shook her head. Morgan rushed into the room then and looked at the two groups of agents in turn. "We missed it, huh?" he said with a snort. His eyes fell to William Reid who was still moaning on the floor. His eyes narrowed. "So this is him."

Aaron nodded, tucking his arm around Spencer's waist. "You should get the paramedics to see him first," he said.

Morgan turned with a stunned look on his face. "Him?"

"I shot him twice."

"He's not being seen over you guys," Morgan said insistently.

The EMTs came into the room then and Aaron stepped aside, with Spencer still clinging to him, to let them by.

Aaron pointed to William when one of the EMTs tried to come to him. "You need to treat him or he'll die."

"It's what he deserves."

"No, Morgan, what he deserves is to spend the rest of his life in prison, and we need justice."

Morgan stepped out of the EMTs way with a huff and he glanced back at their unsub with a murderous look. One of the EMTs checked on Diana and quickly shook their head.

"Don't move her," she said, covering Diana's face.

Spencer, who had been watching with tired eyes, turned his head and squeezed his eyes shut, willing himself not to cry for her.

They had started to lift William onto a backboard when more EMTs rushed in and went to Aaron, William's muffled screams becoming white noise to Spencer's ears.

One EMT looked at Aaron's bloodied forehead but Aaron quickly pushed Spencer upright. "Him first," he said.

Spencer laughed quietly and pulled away from Aaron and Emily. "M'fine," he said, getting his feet to line up straight under him. He pointed groggily to Dave who was also being seen to. He was sitting in the chair which had meant to become the stage for Aaron's murder. Spencer blinked slowly and pointed to Dave again.

"He's been shot," he said.

Emily grabbed his arm. "Spencer, let them help."

"I'm okay."

"Sir, there's blood on your jacket."

"I'm fine."

"Spencer-"

Spencer's vision blurred and turned to blackness so suddenly that he didn't realise that his body had pitched forward and that he was falling.

He never felt the ground meet him... He didn't feel much more at all.
