So this I think may be the longest chapter I've written so far. It kinda dragged on but I liked the way it turned out. And it's been giving me so much trouble, I've like rehashed it so many times and re-wrote parts so many times. It just wouldn't cooperate. Then I sat down and relaxed and kind of let loose and well here is the result.

Summary: Derek Law Number Four: The Sheriff is important.

Derek parked his Camaro next to Stiles' blue jeep. He had just gotten off of work and was ready to pass out from exhaustion. Pulling the key from the ignition, slamming his car door, he stood for a moment. His mind and hearing focusing on what was going on inside his house, trying to pin point Stiles' exact location. Derek groaned when he could hear the faint sounds of gunshots and curse words, Stiles was playing Black Ops.

Derek stalked towards the door, reached for the handle to find it unlocked, again, he'd have to have a talk with the teen about safety. Again. The teen was always forgetting to lock the door. Derek swore that his mate was a child from time to time. The lycan thoughts were broken when his phone started ringing and vibrating in his pants. He reached into his pocket, his eyes reading over the name. The Sheriff was calling him. If there was one person other than Stiles that Derek respected, trusted and cared about it was the Sheriff. Derek wasn't necessarily scared of the authorative figure but well he was a little scared and Derek was always making sure he approached with caution. And reality, he did respect the man, the Sheriff was important to him like Stiles was. Hitting the answer button Derek placed the phone to his ear as he entered his home. "Hale speaking," he said into the phone.

"Derek?"

"Hey Mr. Stilinski, is everything okay?' Derek asked.

"Yeah but I have a big favor to ask you?"

"Go ahead."

"First off, did you work today?"

Derek nodded, which was pointless because the sheriff couldn't see him. "Yeah, I just got off actually."

"Oh."

"Did you need something Mr. Stilinski?

"I was wondering if you don't mind patrolling with me tonight, I could very well do it on my own, but-."

"No, I can help I'll just take a quick power nap because I'm a little exhausted."

"Thanks Derek."

"No problem, so I'll see you in a few hours."

"Oh and Derek, is Stiles there?"

"Yeah he's here."

"Okay, well good luck."

Derek looked at the phone puzzled. Good luck. Why the hell would he need luck?

Derek lay on his stomach, on the bed, arms tucked under his head as he attempted to take a power nap before heading out to help the Sheriff patrol. Stiles, however was making it very difficult. The teen lay completely on top of the werewolf, head resting on Derek's neck and the rest of his body flat against his mates. The teen's eyes were glued to the TV screen, an XBOX controller in his hands as his fingers jammed and tapped at the buttons. Every once in a while his body would jerk or squirm. He could see why the Sheriff said what he said. The teen was all hyped up, and fidgety.

"Stiles," Derek growled, "Get off."

"But Der, I'm comfortable," Stiles stated, eyes still glued to the screen.

Derek shifted a bit, "Then keep still."

"Okay."

Derek let out a content sigh when he felt the teen relax but it didn't last long. Stiles jerked and let out a "Hey you idiot will you pay attention!" Derek groaned in pain when he felt Stiles elbow dig into his left shoulder blade.

"Stiles Stilinski, will you cut it out," Derek growled out again.

"Sorry Derek, but my teammate was being an idiot."

Derek rolled his eyes. "I don't care, cut it out or get off."

Stiles nodded and continued playing. Derek's eyes drifted close again and just as he was about to slip off into dream land Stiles' body jerked. Legs hit against Derek's, both elbows hitting Derek on the back. Derek let out a frustrated growl and in a flash he had Stiles pinned down to the bed. "Stiles!" Derek barked.

Stiles winced. "Sorry Der."

"You either shut up or you'll be in for it if you don't"

Stiles nodded. "Mhmm, okay I'll shut up and play quietly."

"Thank you, I'd like some kind of sleep before I go patrolling with your dad."

"Alright."

Derek rolled over and resumed his original position. "Thank you."

"Derek, can I still lay on top of you?" the teen asked with a childlike voice.

Derek let out a sigh. "Yea, yes you can."

Stiles scrambled on top of the lycan and situated himself as he continued playing his game. Derek let out a content sigh, ears zoning in on Stiles' heartbeat and breathing he began to drift off. The lycan was asleep for about half an hour when he felt Stiles crawl off of him. Derek was in a comfy position and enjoying his nap he ignored the movement.

He felt his body falling back asleep but was suddenly jolted awake when the bed shifted again and there was a persistent pushing against his side. "Stiles," Derek groaned out, "what the hell."

"Move Der, I want to lay with you."

Derek whined. "Stiles, I was having a wonderful nap, couldn't you just-"

Stiles huffed.

Derek opened his eye a crack, he could see Stiles staring at him with a whine. He turned to his side and Stiles immediately dove into the lycan's arms, head buried in Derek's chest and gripping at his mate's shirt. "Do you have to go patrolling with my dad?" Stiles asked.

Derek nodded. "Mhmmm, I already said I would."

"Can I go?"

"No."

"Why not?"

"Cause, you're not allowed."

Stiles sighed as he cuddled closer. "Be nice, please."

Derek smiled a little, "I will."

"I really wish you didn't have to go."

"I have to, you know I respect your dad, and plus it's a Derek Law."

"I don't like that Derek Law."

Derek shook his head, he leaned over and placed a gentle kiss on Stiles' lips, "Hey, it'll fine, I'll behave I promise and I'm pretty sure you dad will too."

Derek sat in the passenger seat of the patrol car. Sheriff Stilinski was on the phone talking to Stiles. From what Derek could make out of the conversation, Stiles was telling his dad "please be nice" and something along the lines of "don't kill him." Derek didn't want to pry and well it wasn't respectful. Respectful would be the right word because the word nice didn't exist in Derek's vocabulary. "I will Stiles," the Sheriff said, "now goodbye son."

The Sheriff hung up his phone and placed it on its holster attached to his belt. He then turned to Derek, "Sorry about that."

Derek nodded, a grin on his face, "It's okay and besides it's Stiles, and it's completely understandable."

"So how's it going son?"

Derek couldn't help the smile that formed on his face, "I'm doing good."

"Still uncomfortable when I call you son?"

Derek shook his head, "No, no of course not, just not used to it, yet."

The Sheriff nodded, "Would you like me to stop?"

"No," Derek cried out quickly

"Alright then."

"Sorry, it's just, don't, you don't have too."

"Alright, I won't, trust me."

Derek turned to him, head tilted to the side, "We didn't come out here to patrol did we?"

"Nope," the Sheriff replied sheepishly, "Sorry Derek but I needed an excuse to get you out here."

Derek nodded, "Fair enough, but if you wanted to talk you could've told me."

"Oh I know, but you see Stiles he nearly went into a flow blown panic attack last time I told him I wanted to talk to you."

Derek nodded. "Yeah, I know."

They were silent for a moment. After a few minutes the Sheriff spoke, he turned to Derek, "Can you blame me? I mean for being so protective of my son?"

Derek shook his head, "No, I don't blame you, and he is after all, all you have left."

"Yeah," the Sheriff breathed, "I love my son and his happiness is what matters to me, I think he'd hate me if I told him to stay away from you."

"You think he would?"

The Sheriff laughed, "Oh no, it's Stiles, you tell him not to do something, he's going to do it."

Derek laughed agreement, "Oh I know that, he's stubborn."

"Yeah, and plus I know it'll break his heart if I tell him that, and I don't like seeing him hurt."

Derek nodded, "Yeah." He leaned forward in his seat, "And Mr. Stilinski, if you did tell him to stay away from me. If you threatened me, I would continue to see your son, no disrespect but I love him. I really do."

"Oh I know Derek, I know you well enough to know that you'd still continue to see my son even if I told him no or threatened you."

"I'm sorry."

"No, don't, I appreciate you being honest with me."

"I love your Son, I hope you know that."

The Sheriff leaned back in his seat. "I know you do. I can see the way you are around him. I know my son loves you too, when you aren't here he talks about you a lot and he gets this grin on his face. I know you make him happy Derek."

"Do you trust me?"

The Sheriff nodded, "I do and I'm telling you the truth, I do trust you but you know sometimes, sometimes I do get a little apprehensive."

Derek smiled, he was content to know that the Sheriff wasn't lying.

"I just need, you know, reassurance once in a while to know that my son is being taken care of."

Derek nodded, "That's fine with me, I'm not trying to suck up or anything but I do respect you, I want you trust me."

"So you don't mind then, if I pull you aside to interrogate you?"

"No, no not at all."

"Good."

"So we good?"

"Oh no, one more question?"

Derek laughed, "Now I see where Stiles gets it from."

The Sheriff grinned, "Annoying isn't it?"

"Very much so, but what's your question."

"You still got control over your Alpha werewolf thing?"

Derek nodded. "Yes, that I do, I have full control over that, I do have moments where I slip but I assure you Mr. Stilinski I always gain it back."

The Sheriff thought for a moment, he then leaned over and started the car. "Fair enough."

"Is that all?"

"Yeah."

Derek relaxed a little, "So what now?"

"You hungry?"

"If you're offering, I'm up for anything."

"Alright, call Stiles up first and tell him to get ready, besides I'm pretty sure he's been calling you none stop."

Derek reached into his pocket and pulled out his phone and sure enough he had several missed calls from the teen. He dialed in his mate's number and held the phone too his ear, the teen immediately answered after the first ring, "Is everything okay?" Stiles asked, rambled, yelled.

Derek winced, "Yes, everything is fine, get ready because we're coming to pick you up."

"Why?"

"Because we're going to eat, and we want you to come, or you know if you want, you can stay?"

"No! Not necessary, I'll be ready."

"You doing okay?"

"Yeah, I just it makes me nervous when you two are alone, I have a bunch if scenarios that go on in my head."

"Sorry Sty, it is a Derek Law."

The Sheriff looked over at Derek when he heard those words. He raised an eye brow and Derek simply grinned at him. "I'm still alive and so is your dad, relax," Derek said.

"Okay."

"We'll see you in a bit."

"Alright, I love you Derek."

"I love you too Stiles."

Derek hung up on the teen and placed his phone back in his pocket. "He's getting ready."

The Sheriff nodded, "Alright, now I'm curious, what in the hell is a Derek Law."

"Oh, umm, it's the laws, the codes that I live by."

"So what's this Derek Law that you and Stiles are talking about."

Derek inhaled sharply and let it out sigh, "Derek Law Number Four, the Sheriff is important."

Sheriff Stilinski laughed, "What?"

"Derek Law Number Four, the Sheriff is important," Derek repeated

"You're serious?"

Derek nodded, "Yes."

"So why Stiles doesn't like it?"

"Because, when you need something, like right now how you wanted to talk, I will be there to talk because you're important and it's a Derek Law and I live by these laws. And he doesn't like it because well it makes him nervous."

"Yeah, alright, you've been hanging around my son too much."

Derek laughed, "You're son is the main reason some of them were made."

"So there's more?"

Derek nodded. "Yeah."

"Do I want to know the others?"

Derek smiled sheepishly, "Umm not really."

"Derek Hale, I think I made a good choice in trusting you."

Not so much of Derek and Stiles' scenes in here, more so a filler chapter, and plus I felt the need to write what it is that I wrote. Plus I needed things going to get on with the other laws that I've got.
