"Are you sure it worked?" Alexis asked after a couple minutes had come and gone. There was a gurgling sound from her stomach and she began to focus on it instead. "I...don't feel so good." She started to spasm before vomiting a thick blue liquid into the bucket that had been provided. After a few moments of that her back arched as her fangs descended. She let out a guttural cry as blood was forced to her eyes. She finally collapsed back into the chair, her fangs falling out of her gums.

"What in the hell was that?" Martha asked as she rushed to her granddaughter's side.

"That was the cure," Sam told her as he picked the bucket up and headed to the bathroom with it. When he returned he turned to his brother and gave him a look.

"Well, we should get outta here," Dean said before grabbing another slice of pizza.

"Wait, you mean you two aren't even going to try and explain what we just saw?" Beckett asked incredulously.

"To be honest Kate I'm not sure I want them to," Castle told her, holding her back gently. "All that really matters is that Alexis is safe and back to normal." He turned to the Winchesters. "If there's anything you guys need feel free to give me a call. It's the least I can do to repay you."

"Any chance at getting a heads up on the newest Nikki Heat books?" Sam asked and Castle couldn't help but smile.

"Dude, you are so pathetic," Dean said to his brother through a mouthful of pizza.

"Hey Dean," Beckett yelled to him as they were stepping out the door. The Hunter turned to look back at the smirking cop. "Your car kicks ass. And if you ever come back to New York I'm arresting you unless you let me drive it."

"She's not an 'it'. She's Baby." With that they were gone.

"I don't know who those two are or what happened tonight," Martha said as she gingerly picked up Alexis' vampire teeth. "I'm just happy you're all okay."

"It might be better that you don't know, mother," Castle said as he picked Alexis up and carried her off to bed. While he was gone Martha turned to Beckett.

"Weren't those the two in the news last year going on that killing spree?" she asked but the detective just shook her head.

"If they are then somehow they faked their own deaths ," she replied. "After seeing how they handled all of this I don't think they're all that bad. Just...misunderstood."

"Well anyone who hunts monsters for a living has to be nuts."

Sam sneezed all over the Impala's dash as they drove through the streets of Manhattan.

"Seriously, Sammy?" Dean asked as he tossed his brother a napkin. "I just detailed her and you go getting your Sasquatch snot on her? It's called covering your mouth."

"Sorry," Sam apologized as he blew his nose. "I just got this weird feeling that someone was talking about us."

"And so you sneezed?"

"It's..." Sam sighed as he wiped down the dash. "You know what, never mind." There was a brief moment of silence as they worked their way out of the city. "So any idea what was up with Cas back there? He should've been able to heal that girl no problem."

"I know," Dean replied. "I mean he took care of that Jefferson Starship thing Eve gave me like it was nothing."

"You think he just ran out of mojo?"

Dean sighed. "I guess he could have," he admitted. "I mean the dude just got out of Purgatory not all that long ago. The whole thing with Alfie proved that he's still not back at a hundred percent. Maybe we just need to accept that Cas can't always pull our asses outta the fire."

Sam stared at his brother in near-disbelief. "Dude, you spend more time calling Cas than you do watching porn," he said finally.

Dean fumbled with his words before settling on, "Shut up...bitch."

"Jerk."

They pulled into a motel just outside the city and Dean volunteered to go on a supply run. As he put it, "I don't trust you to remember the pie." He returned before too long and set the bag on one of the beds before tossing Sam a beer. They did a little research before finally turning in for the night.

Later that night at an abandoned warehouse a door opened silently and closed with a quiet click. The flashlight's beam cut through the darkness enough that Dean was able to see most of what was around him.

"Dean." The Hunter spun around and drew his pistol only to see Castiel. "What are you doing here?"

"Damn it, Cas," Dean said lowering his weapon. "Don't scare me like that." He took a deep breath before looking around. "Sam and I picked up another case. This town's filled to the brim with weird and it seems to be focused here. And while we're on the topic what are you doing here? I thought you were off recharging your batteries."

"I don't have any batteries," the angel replied confused. Dean shot a look at him. "Oh, you mean my grace. I suppose that it's possible my weakened grace drew the 'weird' here." The angel seemed to relax a little bit. "How is the girl doing?"

"You mean the one you could've cured?" Castiel's face fell. "Sam and I managed to cure her but no thanks to you."

"Dean, I-"

"You what, didn't know?" Dean interrupted angrily. "You know Cas I'm getting' real sick of not getting any answers from you. You get out of Purgatory but you don't know how or why. You made me leave you there!" The angel was silent. Dean holstered his gun before drawing an Angel blade. "We're gonna have us a nice sit down and you're going to tell me the truth for once. Got it?"

"I cannot tell you what I don't know, Dean!" the angel replied, frightened by what his friend might do.

Dean punched Castiel right in his nose causing the angel to reel back. The Hunter let loose with a couple quick slashes with the blade. It was enough to hurt Castiel but not enough to kill. "Stop this, Dean!" Castiel pleaded as he grappled with him. He managed to turn the blade away from him and was trying to disarm the Hunter when Dean's strength faltered and Castiel plunged the blade into his chest.

"Cas..." Dean gurgled before falling to the ground. Castiel moved to heal him but it was too late: Dean Winchester was dead.

"Why, Dean? Why did this have to happen?" the angel asked as he fell to his knees beside his dead friend.

"What the hell?"

Castiel turned to see Dean Winchester holding a flashlight on his own corpse. "Did you just gank me, Cas?"

"It's not what it looks like, Dean," Castiel tried to explain but the Hunter already had an Angel blade drawn.

"I know damn well what it looks like, Cas," Dean told him as he began to the circle the angel. "We got into something and you decided that it was better to off me than work things out. Well don't expect the same result twice."

As Dean came at Castiel again another figure watched from the shadows. The fight ensued exactly as predicted as Castiel killed Dean yet again only to have another one materialize out of nowhere. Naomi waited patiently as the scene played out once more.

"This is going to take much longer than I expected," she muttered to herself.

Back in New York a young beat cop looked through Det. Beckett's report to the captain and scoffed. It was a bald-faced lie brilliantly told but a lie nonetheless. Still, there were elements of it that could be used against the detective should the need arise. He reached for his phone and began dialing his boss' number when he heard footsteps behind him. He turned around but before he could act electricity arced through his body and he fell to the ground, stiff as a board but still alive. His attacker picked up the phone and placed it to her ear and listened.

"Well? Is it done?" Timothy Anderson asked over the silent line. "Hello? Are you even listening to me you worthless-"

She hung up, happy with the information she already had. A human commanding a Leviathan, she thought, amused. The King will be happy for this catch. She pulled her own phone and dialed the number she had saved as '666'.

"It's me, sir," she said when Crowley picked up. "The Winchesters were just here and per your orders I didn't interfere. Seems they found out why vampires and shapeshifters were cooperating: survival. Turns out they were just following the orders of a human." Crowley impressed on her that he didn't care about that. "This human also had a Leviathan at his beck-and-call and it looks like it was a volunteer situation. I don't detect any kind of witchcraft. Well, none aside from my own that is. He's ready to be delivered if you want or I can dispose of the freak." Crowley's tone changed when she told him that and ordered her to bring him in and she acknowledged before hanging up.

She picked him up and headed down to the garage where she put him in the trunk of her car, making sure to tie him up. She got behind the wheel and took a quick glance in the rear view mirror, her eyes pitch black. She drove to the entrance where an officer was still on-duty.

"Late night, sir?" he asked as she showed him her ID. "You're good to go. Have a good night, Capt. Gates."

A/N: Well, that does it for the Big Apple. The scene with Castiel is courtesy of 'Reichenbach-Hero'. He suggested it where I completely missed the opportunity. It also gave a good timeline point for the 'Supernatural' part of the story. And while I feel that much of the chapter is rushed I like the options the ending leaves. As a bonus I may have an extra chapter in mind as a sort of tie-in to a possible sequel. I've been toying with the idea but I make no promises. If it's something you feel you want to take on feel free to shoot me a PM. In the meantime thank you all for your support and suggestions but most importantly your patience. Happy Reading! - DragonKnight159
