A/N: I am soooo sorry it's taken me so long to post this final chapter! If you can believe it or not, I had writers block over the spanking scene! I could NOT write it!

DEDICATED TO: Everyone but especially Logan, who was more patient then he gives himself credit for! Thanks to all of you!

OoOoOoOo

Mack ground his teeth, his temper starting to flare. He forced himself to take a few deep breathes to calm his anger, "Do you really think that little of me?"

Hotch flinched at the sound of hurt in his big brother's voice, "That's not…I just meant…" Hotch let out a growl, "I just meant that no one had to force him to start caring!"

The FBI Agent's eyebrows wrinkled, he hadn't meant for it to come out like that but it was too late to take it back.

There was an almost defeated tone coming from Mack. "No one can force me to care Aaron."

"No…You're putting words in my mouth." Hotch let out another growl. The younger man tried to get up but his big brother still had a hold of his arm. "Let me go Mack!"

"Not gonna happen Aaron, so you might as well stop," The grip seemed to tighten.

"You can't tell me what to do," The younger man protested, managing to get himself standing but not released, "Screw you Mack! Let me go!"

Realizing that they were going to get no where, Mack let out a frustrated sigh. He hadn't wanted to do this, this way but he had no choice.

With one tug, Hotch fell across his big brother's lap, bottom up.

"NO!" Hotch tried to get back up, "You can't. Please Mack, don't."

"I warned you what would happen if you didn't settle down and I warned you what would happen if you flew." Mack pinned Hotch's hands to the small of his back and quickly lowered the younger man's night pants and boxers, "This is non negotiable."

With that Mack's hand rose and fell with a resounding swat. Hotch let out a yelp, unable to control himself. "Let me go!"

"No can do kiddo," Mack shook his head, his hand continuing to fall. "I gave you chance to talk and you didn't want to. Fine; it's my turn now."

With that said, Mack let his hand do the talking. The man continued to remain silent until finally Hotch stopped fighting.

"You listen to me," *SWAT, SWAT* "and you listen good." *SWAT, SWAT* "I care about you," *SWAT, SWAT* "because I want to," *SWAT, SWAT* "not because" *SWAT, SWAT* "someone told me to."

"Ok, Mack, ok," Hotch howled, trying once again to get out of his big brother's clutches.

"Oh no, you don't," Mack gripped his younger brother tighter. "Stay still Aaron or I'm going to get the hairbrush out now."

Hotch stilled instantly. 'Oh that's not good,' he cried to himself, trying to remain as still as he could.

"When I give you" *SWAT, SWAT* "an order little brother," *SWAT, SWAT* "I expect you to obey it." *SWAT, SWAT* "If you don't," *SWAT, SWAT* "then this" *SWAT, SWAT* "is what you can expect" *SWAT, SWAT* "every time." *SWAT, SWAT* "You understand me?" *SWAT, SWAT*

"OW! Y-YES!" Hotch cried out, not bothering to try and hide his tears. "Mack, I un-understand!"

"Good!" *SWAT, SWAT* "Then understand this," *SWAT, SWAT* "every time you put yourself," *SWAT, SWAT* "in ANY sort of danger," *SWAT, SWAT* "I'm going to spank you the moment" *SWAT, SWAT* "I find out your ok" *SWAT, SWAT* "and then again that night." *SWAT, SWAT* "You understand that?" "*SWAT, SWAT*

"Y-yes sir," Hotch bowed his head, any thoughts that his big brother didn't care were leaving. "P-please M-Mack; I-I'm sorry!"

Giving the younger man's back a slight rub, Mack spoke gruffly, "We're almost done pup."

"No Mack!" Hotch wiggled, testing out his brother's strength that was restraining him.

Mack found himself hesitating briefly before bringing down the item in his hand with a loud smack against the red backside. He wanted to end the punishment but knew to stop now would be a mistake. He wanted…no he needed Hotch to understand that he cared; that he, Mack, loved his baby brother.

It was with that thought he steeled his heart and continued to pepper the up turned bottom with harsh smacks of the brush.

"MACK!" *SMACK, SMACK* "I-I'm s-s-sorry!" *SMACK, SMACK* "P-please, I won't do-do i-it again!" *SMACK, SMACK*

Realizing there was no where for him to go and nothing for him to do; Hotch went limp over his big brother's lap and sobbed.

Mack brought the brush down a total of a dozen times, all of which were on the tender under curve, before stopping.

He all but threw the brush against the other side of the wall before gently sweeping up the younger man's boxers and night pants and righting him.

He needed to hold his baby brother close, if not for Hotch's sake, then for his own.

OoOoOoOo

"I-I'm sorry," Hotch hiccupped; his tears finally coming to and end.

"I know pup," Mack's voice was thick with emotions that he would never confess to. "Come on, let's get you into bed."

Mack gently eased Hotch off his lap and onto the bed, stomach first. He pulled the blankets up to the younger man's chin. Seeing the forlorn look in Hotch's eyes, Mack sat on the bed, allowing Hotch to put his head, in his lap.

Knowing that the earlier discussion wasn't fully over, Mack asked, "Why do you think Jonas had to force me to like you pup?"

"You didn't even like me when we first met," Hotch pointed out sounding years younger then he was.

"You're right," Mack agreed. "But if I remember correctly, the first time we met, you'd just thrown a glass of juice towards Jonas but instead hit me."

Hotch winced, "Um…sorry?"

Mack rolled his eyes, "If I'm correct you were later that night."

Hotch blushed and looked down. He'd never forgotten about that day when, in his anger at not being able to have a beer, he'd thrown his glass of juice at the man he thought of as a dad. When Jonas has demanded he apologize he'd thrown Jonas's can of pop on the ground, spraying Jonas and, once again, Mack.

"I apologized," Hotch's voice was low and showed his hurt.

"You're exact words were, 'I'm sorry you're such an ass'," Mack raised an eyebrow, "You were mad at me because Jonas had spanked and grounded you. You seemed to think it was my fault so every time I came over you made sure to make me feel unwelcomed."

"How could I make you feel unwelcomed?" Hotch looked up, eyes wide. "You're on Jonas's team…you guys are like brothers."

"And you're his kid," The older man vocalized. He shushed the younger man up with a pointed look, "You are his son in every way that counts. You didn't except me into your family Aaron, how was I supposed to feel?"

"I…I never..." Hotch looked baffled, "I always thought you hated me."

"I never hated you kid," Mack confirmed, "You weren't my favorite person either."

"What made you change your mind?" Hotch looked up, the fear gone from his eyes, in its stead was a true desire to know the answer to his question.

"You ran away," Those were all the words that were needed for the moment as both were consumed with the memories of that fateful day.

The two had gotten into a disagreement that had ended with a particularly harsh lecture from Jonas Blaine. Both men had been shocked but of them, Mack, had been the one who understood. The unit had just lost one of their own and every ones emotions were high.

Angry, Mack has gone to the gone to the gun range. Seeing him storm away, Jonas had told Hotch to go take a nap. His words were neither gentle nor harsh but after the blistering lecture Hotch read between the lines and found a message that hadn't been put there.

It was an hour later when Mack got the call that FBI Agent was missing. At the moment he hadn't really cared; he'd gone back to his team leader's house for the sake of said leader, nothing and no one else.

"Mack…" The sound of a timid voice brought the older man back to the present.

"Me and Jonas found your footprints," Came the explanation. "You had back tracked so Jonas went in the direction of those figuring you'd remembered at the last minute that they were fixing the gate behind us and there were guards protecting the section."

Mack's grip tightened as he remembered the scene he came to. "I followed your first set of prints just in case."

"I'm glad you did," Hotch replied with a shudder remembering all to well the situation that his big brother had come upon.

No one should have gone through the woods to begin with let alone on that day. Hotch has walked out and immediately two trained guns were on him; the men yelling.

It took Mack and Jonas, who showed up after hearing the commotion, to explain the situation. Hotch had been shocked to here his 'dad' lying and telling the guards that they were showing Hotch around when they became separated.

What pull Jonas had, his son still didn't know, but the situation was never brought further then that point.

"That's…" Hotch didn't finish his thought but he didn't needed to.

"Yup," Mack supplied peering down to look at the brother.

That day was the first time Mack had ever given Hotch a hug…right after he swatted him.

"Go to sleep," Mack finally murmured, "We still have a drive."

Hotch nodded and within seconds of closing his eyes be was out like a light.

It was almost an hour later when Mack finally put his head against the head board and fall asleep, content to hold his brother through the night…

EPILOGUE:

The sound of multiple voices greeted the man who rang the door bell.

"Get the door someone!" A deeper voice then expected called out.

"Thanks for the help, Derrick!" The voice he was expecting grumbled as the door opened, "Can I…J-Jonas?"

"Aaron," Jonas Blaine stood staring at his 'son', "Gonna let me in boy?"

Hotch blushed as he beckoned his 'dad' in the house, "Sorry, sir."

Before any words could be exchanged the two were interrupted by the sound of someone running down the stairs, "Uncle Aaron, can I…uh…sorry Hotch."

The younger man sprinted back up the stairs. Hotch grinned at his guest as they listened to the sound of the young man running down the hall and down the back stairs.

"Am I interrupting something?" Jonas grinned.

"Family dinner," Hotch grinned back, "Want to come meet them?"

"Lead on son," Came the answer.

Hotch led the way through the house. There was a slight tension that hung but as soon as the two stepped into the back yard, Jonas gave the younger man a hug, "Relax; we'll talk later."

Hotch nodded as he beckoned for the two by the grill to come over, "Derrick, Spencer, I'd like for you to meet Jonas Blaine; Jonas, meet, Derrick Morgan, and…my nephew, Spencer Reid."

"Nice to meet you," Morgan greeted with a handshake.

"Hi," Reid's voice was quite and Jonas could tell that the youngest man of the group was awed by the way he was introduced.

"Nice to finally meet you all," Jonas smiled, turning to Reid, "Well, son, I'm not sure I'm old enough to be a granddad yet but, I'm willing to give it a shot."

While Reid blushed Morgan raised an eyebrow at his boss. He understood instantly the connection between the man who had shown up and the man who he looked to.

Instantly seeing a nervous in said boss that he wasn't used to, Morgan offered, "Why don't you two catch up and me and Reid'll get the food on the grill."

"Good man," Jonas boomed, turning to lead his son back inside.

"J-Jonas, I…" Hotch's voice trialed off sadly.

"Mack explained everything little boy," Jonas's voice was stern. "However, he also told me he took care of it. So, just this once, will I let it go. Be warned, if it happens again, you're going to be dealing with me on top of your big brother. Got it?"

"Yes, sir," Came the instant reply; a hint of relief coloring the words.

"Good boy," Jonas took a seat in the living room, "So, tell me more about your family. Mack's gonna be upset he missed meeting his nephew and my guess is, other brother?"

"More like step-brother," Hotch half agreed, "Maybe you two can come down some time?"

Seeing a nod, Hotch began his story. How the three most unlikely people came to be a family that each of them needed. It was the same story that brought him, Jonas, and Mack together also though he was just starting to see it for himself.

Jonas sat back and listened, already planning the visit that would take place. After all…they were family.
