A/N #1: I was pleased to receive what I did in feedback for the last chapter so I'll get started on my thank yous for that! TORONTOSUN (I was pleased to see you think the last chapter was really good writing. Also how everyone is comfortable together, it went well with this story, lol) and

Mb (I was really happy to see that you thought the first half of the chapter was a nice filler chapter with Skye arriving. The same with the background on her cases and if it would connect with the murders. I wasn't surprised you thought it was great that Julia was using what Skye had taught her when spirits try to talk to her. I figured that would start kicking in, lol. Great you thought the first half was nicely done! You're welcome for the first half too! I wasn't surprised that you mentioned how the second half of the chapter was slow, I did want a little bit of a break from the case for a little, so that's why I had the lunches, also I did want to mention future stories too, with the vacations. I wanted to bring in Mary since I figured it would do as you said, keep Skye balanced. And of course the same with Darnley so I'm glad you noticed! I had to laugh at you mentioning how it went boom to their possible suspect and the cliffhanger, lol, I do like doing that since it keeps readers on their toes. And you're welcome for sharing the second half of the chapter! Happy Thanksgiving to you and yours this week as well!)

Thanks for the reviews, I loved reading them and I appreciate the time taken to write them out and send them my way!

A/N #2: The title of this chapter is a lyric from the song Dead Man's Party by Danny Elfman, from the Oingo Boingo album the same name as the song.

Goin' To A Party

"Andrews!" Brad yelled trying to squeeze the young man's wrist to get him to let go of his gun. "Andrews let it go or-"

"Shoot me! Shoot me or I'll shoot you!" the young man was yelling while Beckett and Darnley were getting him away from the chief and Castle.

"Cuff him," Beckett said, straining to hold onto Andrew's arm.

"Dispatch," Brad said, standing up. "Call an ambulance-"

"I don't need it," Castle interrupted his friend in annoyance.

"No, but he does," Brad said in obvious anger. After Andrews was sitting on the chair again, he went to the young man and said into his walkie-talkie, "I need an ambulance, I have a man, age twenty-four who is going to need a mental evaluation. Advise the ambulance he'll need to be taken to Mercier General."

"You were hit," Beckett said, having gone to her husband once Andrews was taken care of.

"No, but it did ruin these pants," Castle said, his voice still tinged with irritation since the gunshot had grazed him. "I can go and change right?"

"You need to go home," Brad said.

"No, we keep clothes in the car," Castle replied before they were looking at Andrews when he was rocking on the chair.

"Take it easy," Darnley told the young man warningly. When he didn't stop, he said, "We could lay him on the rug over in the living room," not surprised the officer he was assisting was immediately reacting to that.

"That would help?" Bernier asked.

"It's helped before in D.C. and it wouldn't hurt to try," Darnley said, looking over at the chief with the officer. When Brad nodded, they moved together to literally carry Andrews to the family room where they lay him stomach down on the rug. He knelt next to the young man to make sure he would be alright.

Watching Andrews soon calming down, Brad said, "What do I do with the parents outside?"

"Would they want to stay?" Bernier asked.

"They did rent the property," Darnley commented.

"I would ask them," Castle said.

"And yes, I would offer a detail to keep an eye on the house," Beckett replied when Brad was turning to her.

"Alright, keep an eye on him, the ambulance should be here soon," Brad said before he was leaving the house.

"I'm fine," Castle told his wife when she turned to him.

"I know, I was going to ask you not to do that again," Beckett replied simply.

"Oh trust me, I'm going to do my best not to," Castle said, reaching to her free hand and squeezing it briefly. He then said, "What do you think?"

"He's not the killer," Beckett replied in a matter-of-fact tone of voice. "Not with that reaction."

"No, even Mother would agree that wasn't an act," Castle said. "He's lucky, if he hadn't repeated about them being together, I would have said he was just her killer."

Nodding, Beckett looked towards the open front door when they could hear the sirens in the distance. "I get the feeling we're going back to the station," she said, a little startled at her husband's response.

"Though I am wondering about Breck," Castle said.

"Obviously it wasn't Breck," Beckett said.

"Yeah," Castle commented slowly before the chief was walking back inside to them.

"I need you three to return to the station," Brad said rapidly. "And help Rice and Hall with the names."

"Breck?" Castle asked him.

Shaking his head rapidly Brad said, "Breck has been cleared, time wise nothing makes him the person in the costume. I'll be getting in touch with Hutchinson to contact Almer to check about his costumes."

Since Breck had been dressed as an Old West sheriff when they'd seen him, Beckett said, "And he's clear?"

"No but that's what Rice needs to work on," Brad said. "Make sure you see if Skye and Nkosi have anything," he added. "It might not deal with our case, but I want to know."

"We'll tell you when you're back," Beckett assured him while they turned to watch the EMTs entering the house with a stretcher.

"What do you think?" Nkosi asked his fellow investigator.

"That I don't want to tell Brad," Skye answered immediately. "You're brave," she added before he was snorting and speaking wryly.

"You need to," Nkosi said. "You were here first, and these are your cases."

"Fine, I'll tell him when I see him," Skye replied, pretending to be annoyed.

"Tell him what?" Beckett asked, she, Castle and Darnley walking into the room the two were in.

"That this bracket is from an Embraer," Skye replied.

Startled when the writers were suddenly looking at his husband, Nkosi asked, "What did you tell them."

"I could have sworn it was for a Cessna," Darnley said in dismay.

"It's similar though this isn't for the engine," Nkosi replied. "It's for slats."

"Does that mean anything?" Castle asked the investigators.

"First it means that it is connected to my cases," Skye replied. "So I suppose I have a reason to be here."

"And second?" Castle said.

"That I will be staying," Nkosi said. "Though I don't know if Brad will be happy about that."

"He won't mind," Beckett said.

"You're so sure?" Nkosi replied.

"He better not," Darnley said. When his husband glanced at him in obvious confusion he said, "I'll talk to him, I promise," before he was turning to Skye when she was commenting with a smile on her face at the same time.

"I know you're thinking we don't need you, but I could use your knowledge of these cases," the investigator said.

"I… okay I do know your cases," Nkosi started to say before he made a face and then spoke swiftly. "But I'll only help when necessary; I'll tell Brad that." He hesitated and then looked around asking, "Where is he?"

Seeing the three shifting and looking at one another, Skye said, "Nothing bad I'm guessing."

"We did come back here," Castle commented.

Glancing at Darnley, and seeing him smiling at her, Beckett rolled her eyes before she then related what had happened at the rental house. "We haven't heard from Brad yet, but I'm guessing he's either not going to be able to talk to Andrews or he'll have to recover before that point."

"Which may take time," Darnley said.

"And do we believe he's the killer?" Skye asked them.

"Not really," Darnley said.

"I told Hutchinson to contact a few people who were at the event we interviewed already, some teachers and students," Beckett added.

"Now the names?" Darnley inquired. "Skye told me," he added quickly when the others were looking at him in surprise.

"Also, are we supposed to help you?" Skye asked them.

"Why do I get the feeling you're going to be looking at your own case?" Castle said. "Cases."

"You are, Trevor managed to get his hands on a microscope, and we compared the metal of the bracket with the parts in the three crashes," Skye said.

"They match," Nkosi said. "And I can say for sure that the addition of iron added to the brittleness of the parts."

"Does that help you find out where they came from?" Darnley inquired.

"No but it's a place to start," Skye said before her co-investigator could. She then turned to the others and said, "There are a number of places where that iron could have been provided from, so we'll need to look into any break ins." She saw Castle had raised his hand slightly and she said, "Yes?"

"Doesn't that fall under the FBI's jurisdiction?" he asked, his brow furrowed.

"Oh of course," Skye started to say.

"And they will look too," Nkosi continued. "We contacted them already."

"But the companies won't talk with federal agents," Beckett guessed. She rolled her eyes with a brief smile when Skye was tapping at her nose and said, "Do they know you're going to call."

"The companies they're going to talk to are legal, but they might be indulging in practices that aren't," Skye said.

"And you think they'll talk to you?" Darnley asked in obvious confusion.

"Yes, because they won't know it's us," Skye answered. "We have a few tricks."

"Are you going to be good calling from here?" Beckett asked them.

"Yeah," Nkosi said. "We'll use those two phones they brought for us."

"Are you going to your desks?" Skye said.

"Yeah," Castle said, watching his wife leaving with a frown. He shook himself, turning back to the pair and saying, "This would help our case."

"I'm hoping," Skye said.

"Hoping what?" Darnley asked with a frown.

"That the iron was stolen," Skye said.

"What if the killer distorted the metal themselves?" Beckett asked while she was walking inside the room with two notepads of paper since the investigators only had a few pieces of paper with them.

"It would be far easier to find them," Nkosi said. "It's difficult to do that on your own without someone being aware of what you're doing."

"So we're hoping for something," Skye added.

"What about the victims?" Castle asked.

"You want me to contact them now?" Skye replied with her own question before she snorted. "You explain to Mary if something happens to me," she said.

"Hold on," Beckett said, holding her hand out to Skye. "You don't need to try anything if it's going to hurt you," she explained. "You have your investigation to focus on anyway."

"Just a thought," Castle said before he realized Skye was looking at his feet. He was about to ask her what she was doing when she was speaking with a touch of amusement.

"What happened to your trousers?" Skye inquired.

"Oh," Castle said, glancing down at the leg of his pants. "I forgot I was holding this," he said, since he had a bag with a new pair inside. "I'll be right back."

"Wait, did he get shot?" Nkosi asked with a frown.

"Brad's gun went off accidentally," Beckett explained.

"He's not hurt is he?" Skye said.

"No, it just grazed him," Darnley said. "So… we're leaving?" he asked.

"I think we need to," Beckett said, checking the time.

"You can if you want to," Skye told her. "Just let us know when you're going to leave."

"We will," Darnley said though he was looking at his husband while he spoke.

"Come on," Beckett said with a smile, pulling him after her while she was leaving the room. Once they were in the bullpen she went to her desk before her friend was watching her with a slight frown.

"You took a picture, didn't you?" Darnley asked her.

"I did, you didn't?" Beckett said with her own question.

"No, excuse me," Darnley said, stepping aside the desks and going to Brad's office.

"You guys got kicked out?" Castle asked, walking over to his wife.

"Of course," Beckett said. "You saw all those names."

"Where's your phone?" Castle said, sitting in the chair next to her. He wasn't surprised when she was handing over her phone immediately after and said, "First one is Regan Eccleston." Watching her typing he told her, "This is going to take a long time."

"That's why we're likely leaving once Brad's back," Beckett said absently.

"Maybe I should have made us some coffee," Castle commented.

"Nothing," Beckett said, studying the information about the employee. Looking at her husband she then said quickly, "Nothing unusual about him. And tea sounds better."

Looking up when Castle was giving a mock groan, Darnley asked, "Do I dare ask what's going on?"

"My wife just volunteered me to make tea for everyone," Castle replied, standing up. "Do you want anything?"

"Just a cup of tea," Darnley replied. "Though what're you making?"

"Earl Grey," Castle said, heading towards the room Skye and Nkosi were in. "And I'll be back," he added, not surprised when the carpenter was waving at him, and his wife was still staring at the computer screen intently.

"Great you guys got a start on things," Brad said, walking into the bullpen. "Though where is Rick?"

"With Skye and Trev," Darnley answered.

"He's helping them with the phone calls they had," Beckett explained when the chief looked confused.

"I am so far behind," Brad said, shaking his head.

"So are we," Darnley commented. "Andrews?" he asked.

"Okay," Brad replied. "Let's gather over there," he told them, standing up and leading them over to the room. When he opened the door, he froze since Nkosi was yelling on the phone.

"No I don't blame you, but you have to tell the FBI before things get that much worse for you!" the investigator was yelling before he slammed the phone down, looking up in surprise when his fellow investigator was speaking first.

"Maybe I should call the FBI and let them know," Skye commented.

"No I… I've got it," Nkosi said, exhaling.

"I think you need to let her Trev," Darnley said.

"Oh, you're back," Nkosi said in surprise, seeing his husband. "Is everything okay with the suspect?"

"He's not a suspect," Brad replied. "And do you need to make that call?"

"Give me a second," Skye replied, looking at Nkosi before she was on her cell phone.

"I'm going to guess Andrews is okay," Castle told his friend.

"Where did you get that cup?" Brad asked.

"I ducked out while you were staring at Nkosi," Castle replied, watching his friend taking the mug of coffee.

"Thanks, I needed this," Brad said, raising the mug to his friend before they were looking at Skye.

"Okay, they'll look into Tracer Productions," the investigator said.

"That's on the west side of the island, isn't it?" Castle asked his wife.

"It is," Skye replied. "And they had a break in four months ago," she added, putting her phone away.

"Which they didn't report," Nkosi snapped in annoyance before his husband was speaking swiftly while he walked over to him.

"And they're probably going to get in trouble for that," Darnley said soothingly. "And it might help your cases."

"He's right," Skye replied. "And they're going to look into the robbery, there were security cameras." She then turned to Brad and said, "You can go ahead and tell them what you've learned."

"Not much," the chief said. "Though you two are telling me about what you got." At their nods, Brad then said, "What I learned is that Andrews is on the Autism spectrum."

"That makes sense," Castle said. "His reaction."

"I met his parents since they were called to the hospital," Brad answered with a nod. "And speaking to them he's done this, focused on a woman or man to that degree you saw."

"He's bisexual," Castle commented.

"He's the one that is," Brad said. "I confirmed it with Mr. and Mrs. Garnett."

"Then can we confirm the story he told us?" Beckett inquired.

"I did, his parents said that they keep an eye on him by tracking his phone and when they told me the address of where he was it was where Andrews told us he'd been," Brad explained. "And they told me he'd said there was something weird going on with her, Lyla."

"She was dating Breck," Darnley said.

"No," Brad replied. "She wasn't dating anyone. When I spoke with the Garnetts they told me she was focusing on her career choice."

"Then who was the man that picked her up?" Darnley asked.

"That was the weird thing," Brad replied. "Hutchinson asked the students she called, and they said there was someone walking around the campus the last two weeks."

"Doing what exactly?" Castle asked in confusion.

"Just walking," Brad said. "And there will be come security footage, but they said they were wearing a costume with a mask."

"Then you're so sure this person has anything to do with your case?" Skye asked.

"We're hoping," Brad said simply.

"I hate to tell you that didn't make much sense," Skye said.

"She's right, there was something weird about Ms. Barnett but then you go into a person walking around the campus," Nkosi said.

Nodding in agreement with him, Skye then told the chief, "Unless we're going to see him stalking the four then I don't get it."

"I wasn't finished," Brad said. "Her parents told me she'd been getting e-mails from someone telling her they'd been watching her."

"That makes a little more sense," Castle said, looking at the two.

"I think you're going to need that footage," Skye replied.

"They're getting it for me," Brad said. "So… which one wants to be next?"

"We will because we don't have a lot yet," Skye said. "We confirmed the bracket is for an Embraer."

"He wasn't that far off," Nkosi said in a rush when Brad began to frown. "The bracket for the Cessna and the Embraer is close but just slightly different in size."

"And he compared the metal with the pictures of the other parts we have from the three crashes," Skye said.

"With that it allowed us to narrow down where exactly it would be," Nkosi then took up. "There were six and on this side of the coast."

"Why?" Brad said in confusion.

"They're building up supplies to sell them at a higher profit," Castle said.

"Which isn't illegal," Skye said, nodding at him briefly. "But if that impure metal was mixed with something else then you have the three crashes we were investigating."

"And you managed to find one that had a recent robbery," Beckett told her.

"And we're going to get some security camera footage," Nkosi added. "So we'll take a look at it and show you what we find."

"You were going to need to," Brad said.

"We have nothing," Darnley said when the chief looked at the three of them.

"He's right," Castle said, glancing at his wife who was rolling her eyes. "We've gotten a good portion of the employees at Eris set."

"But there's a ton more," Brad said before looking at his watch.

Surprised when the chief was swearing, Beckett said, "You forgot to tell us."

"I was waiting in the hospital for a while," Brad said, shaking his head. "Are you two getting that footage tomorrow?"

"I was about to say but I suppose it was better you heard from them," Skye said.

"You don't have to let us go," Beckett said.

Shaking his head Brad said, "I'm obligated not to overwork you three." He glanced at the investigators and said, "And I'm assuming the NTSB wouldn't be happy if I did that for you two either."

"Probably not. But seriously we've missed most of the dance class," Castle said, checking the time on his watch.

"He's right, we can help you for a little longer at least," Darnley informed him.

"No," Brad said. "And I'm saying that because I need your help with the murder boards. I want them updated while I call start calling myself."

"And your information?" Castle asked in obvious confusion.

"After you guys are finished," Brad said simply.

"Then… I guess we're going," Darnley said slowly.

"You are," Brad added firmly.

As his friend was leaving, Castle shared a look with his wife before he was shrugging, and they were walking together after the chief.

Stretching her leg, Julia made a face at Mari when she walked up to her and said, "I'm fine."

"Did you get another leg cramp?" she asked.

"No, but I feel a twinge in that leg," Julia commented. When she straightened up, she said, "What are you thinking?"

"That you're worried," Mari said simply.

"Close," Julia said with a smile. "More I want to talk to Skye," she said. "But since they're still working…" she said before trailing off and shrugging. She moved her leg off the ledge of the planter and was about to speak before she heard someone mentioning the words Hofstra and Halloween.

"You're sure Ryan is alright?" one boy said to another.

"I guess, I mean it was his cousin that got killed," the other said, shaking his head.

"How'd you hear that?" Julia asked, hurrying over to them.

"My dad works at Hofstra," the first said. Recognition suddenly appeared on his face, and he said, "Your parents work with the police, don't they?"

"Yeah," Julia said, hesitating when she realized she had likely just revealed the cousin had been murdered.

"No way, Piers was killed?" the teen asked in shock.

"Yeah," Julia repeated weakly.

"Do they know who did it?" the other boy asked.

"No, they're investigating still," Julia said. "Did you know the guy… Piers?" she asked then.

"Oh, I did," the teen said, straightening up a little. "My name is Chad, and this is Del."

"Hi," the other teen said, raising his hand to them.

"Did you see him before yesterday?" Julia then asked.

"No, but if you want to know about weird stuff there was that reporter that came here and was bothering Ryan," Chad said.

"I remember that," Mari said. "Remember I told you?" she told her friend when Julia turned to her.

"Oh yeah," she replied. Julia then turned to the two teens and asked, "Did you see the reporter?"

"Yeah, we were with him," Del said, nodding rapidly. "He was tall, red hair and had really tiny eyes."

"Did he tell you his name?" Mari asked, surprised he hadn't begun with that.

"I think," Chad replied. "Hard to tell though because he was talking super fast."

"Shoot," Julia said in annoyance. "My phone is dead. Do you have yours?" she asked Mari.

"I forgot it," she admitted. "Mom said to use yours if I need it."

"Could I use your phone?" Julia asked the two.

"I don't bring one, my dad won't let me," Chad said.

"It died during lunch," Del said quickly when Julia turned to him.

"What about Eliza?" Mari asked her friend.

Shaking her head Julia said, "She doesn't have it." She let out a huff of frustration before she said, "I guess I'll have to tell them when they come… hopefully they won't have to go back to work."

"Do you know who the reporter is?" Chad asked.

"Of course, it's Mack Kipling," Julia replied. "He spoke with my parents about the other reporter at the paper who got killed by a bomb on the beach."

"Jules!" Eliza cried, hurrying up to the others. "You didn't come to pick me up."

"Sorry, I found out something for the case Mom and Dad have," Julia replied.

"Hey, we have to go, my mom will try to call me," Chad told Del.

"Alright," the teen said with a nod.

"Thanks for helping!" Julia called to them before they were leaving. She wasn't surprised when they were calling back a your welcome and then said, "Let's go before we're late."

"Are Mommy and Daddy going to have to keep working?" Eliza asked. She wasn't surprised when her sister didn't immediately answer as they were rushing across the quad without running until they were inside the high school building.

"I'm hoping not," Julia said.

"But won't they? You told them," Eliza said.

"My phone is dead," Julia replied, not surprised when her sister looked at her in surprise.

"Oh… so you have to tell them later?" Eliza asked.

"Hopefully they come to the class," Julia said.

"Hopefully," Eliza said in agreement before they were entering the dance studio. Going to the girls' changing room she said, "Did you put your clothes back on?"

"No," Julia said with a smile, taking off her coat.

"I was wondering why you had leggings on," Eliza commented.

"I go out to pick you up remember," Julia replied, hanging her coat on the side of her locker.

"But you don't need to," Eliza replied.

"Tell Mom and Dad that," Julia said before she looked over at Mari. "What's wrong?"

"Nothing," she replied with swiftly. She hesitated for a moment and then asked her, "Do you think a reporter could have done that."

"Done a killing?" Eliza asked.

"Murdered someone," Julia told her sister. "And I don't know," she then directed to her friend. "He could, Mom and Dad say anyone could, but they'd have to find out first."

"Do you want to ask someone else for a phone?" Mari asked her, seeing the troubled expression on her friend's face.

"Girls, we're all ready here," Ms. Grey called into the room. "We need to start the class."

"I'll have to wait," Julia said, rolling her eyes before she followed her sister and friend outside the room in a rush.
