Sean Hotchner looked around curiously. He had absolutely no idea where about his brother was working. Luckily a man was approaching him, hopefully to guide him to find his brother.

"Can I help you sir?" The man asks kindly

"I'm looking for Aaron Hotchner"

"Agent Hotchner? May I ask what it's about?"

"I'm Sean, his brother" Sean replies showing the man his driver's licence as proof of his identity.

"Ah yes, if you take the elevator to the second floor, you should see him and his team" The man instructs

"Okay, thank you" Sean replies kindly before walking over to the elevator.

Sean could see his brother through the glass doors. It looked like he was giving instructions to his team. He could wait for them to finish, or he could walk in and piss his older brother off. The choice was obvious.

"Aaron" Sean walks in to the office area. Hotch had been facing the other way but turned around when he recognised the voice.

"Sean, what are you doing here?" Aaron asks sternly, knowing his brother was probably up to something.

"Am I not allowed to visit my brother?" Sean replies sarcastically, grinning at his brother

"Brother?" Agent Emily Prentiss asks curiously

"You never visit me unless you want something, and yes this is my younger brother Sean" Aaron answers his agents question "Sean this is my team, David, Emily, JJ, Spencer, Derek and Penelope" He points out each individual as they all welcome him.

"How come you never told us you had a brother?" JJ asks her boss. She liked the look of Sean, he had waxed up blonde hair and matching bright blue eyes. He was really good-looking.

"Yes Aaron, how come you never told them you had a brother?" Sean smirks at his older brother, who narrowed his eyes at him, giving him the look he had mastered after years of practice, the 'I'm-going-to-kill-you look'.

"It never came up"

"Sounds about right" Sean murmurs

"Is there something you wanted Sean? We're trying to do some work here"

"Hotch we only just finished our last case, I'm sure we can wait a day to start the next. I want to get to know your brother" Emily smiles at her boss, who didn't look very pleased but didn't argue. He pulled Sean a seat next to himself and made him sit down instead of 'standing like he owned the place'.

"So, Sean, you don't look very old? What are you doing? College?" Morgan asks the young man

"ur yeah I'm at Cornell studying to become a doctor, but I'm taking a break at the moment"

"That's all you ever seem to be doing" Aaron eyes his brother

"Save it Aaron" Sean glares at his brother

"What was he like growing up?" JJ notions to Hotch, trying to diffuse the argument before it properly started.

"What was Aaron like? Well what were you like Aaron?" Sean grins at his big brother "I have so many stories I could tell, but which ones…"

"Just remember I can still kick your ass Sean" Hotch warns his brother, earning a stifle of laughs.

"I'm sure you can old man" Sean winks at his brother "However, I'll take the risk"

"Go on" JJ goads him on, earning a glare from her boss (which she chose to ignore)

"When Aaron was 13, we went swimming with our mum at the local pool" Sean smirks at his brother who had a grip on his shoulder "Don't carry on with this story Sean"

"Come on bro, it was a long time ago and it's funny"

"I'm serious Sean" Hotch orders sternly. A second later the phone rang in his office.

"I'll be right back, keep an eye on him, don't let him read, touch or even look at anything" Hotch instructs his team, giving one final warning glare to his little brother.

"Well who wants to hear the story?" Sean grins once his brother had left.

"I don't know Sean, he really didn't want you to tell it" Reid looks at the slightly younger man

"Only because he's still embarrassed, anyway what's he going to do?"

"Apparently he can kick your ass" Morgan smirks slightly

"Yeah right can he, he can't fight"

"He's an FBI agent" Reid looks at him as if he is stupid

"Fine, maybe he can, but he would never purposely hurt his beloved little brother"

"You willing to take that risk?" Rossi asks

"Of course, so basically it was summer and we were at the local pool…"

*14 years ago*

"Aaron! Wait for me! Mum said I'm allowed in the big boy pool with you" A small blonde haired 6 year old followed his brother.

"Sean, you're not big enough for this pool, go back to mum" The 14 year old turned around and hissed at his brother who was making a scene.

"But Aaron" The boy whimpers

"Don't start crying Sean"

"Please"

"No, now leave me alone, I'm going to find my friends" Aaron walks off leaving his brother standing there.

Once Aaron was at the big pool, he scans the area for his friends Jimmy and Eric. He sees them and rushes over to them, they were in the pool. Aaron was about to step in when he sees a group of girls from the grade above. This was his chance to impress. He does a short run up before jumping up and doing a cannon ball in to the water. It would have been brilliant…if his shorts had stayed on.

It took Aaron a moment to realise his shorts were no longer part of him, but not his brother, who found it hysterical.

"Aaron! Your shorts fell off! You're naked!" He shouts across to his brother, by now the entire pool was looking at him and laughing. Aaron quickly grabs his shorts from next to him and pulls them back up. His face was bright red mostly from embarrassment but some was anger.

"Sean!" Aaron shouts angrily before setting out full pace after his fleeing brother.

"The day ended with Aaron not going back in the pool out of embarrassment" Sean finishes. Hotch's entire team were laughing hysterically. They couldn't control themselves when he walked in the room a few minutes later.

"I'm back that was-" Hotch stops dead in his tracks when he notices his entire team laughing and his brother looking at the floor innocently.

"You little…Sean you're a dead man!" Aaron threatens walking over to his brother, who had got up and was standing as far away as he could in mock surrender.

"I didn't do anything" He laughs

"You told them! I told you not to tell them that story!" Aaron was now directly in front of his brother, glaring down at him.

"They thought it was funny"

"It was better than funny! It was amazing!" Emily says still unable to control her laughter

"Don't hurt me" Sean begs his brother with his biggest puppy dog eyes

"What happened to him never 'purposely hurting his beloved little brother'?" Morgan grins at the blonde man

"Is that what he said?" Aaron turns to Morgan who nods then back to his brother

"Well beloved little brother, looks like this will have to be accidental then" Aaron smirks slightly

"Aaron, you know you love me" Sean smirks back

"You know what Sean, I'm not going to hit you" Aaron begins

"See guys, I knew he wouldn't hurt me, because he's my favourite brother"

"I'm your only brother"

"Even if you weren't you'd still be my favourite" Sean grins his signature grin

"Instead, I'm going to tell one of my favourite Sean stories" Aaron winks at his little brother

"No Aaron, come on, I think you tortured me enough when we were kids, this was just payback for all those times"

"Oh come on Sean, let your big brother have some fun"

"I've never seen this side of Hotch before…I love it" Garcia whispers to JJ who nods "Little brother's always bring the best out of us"

"Well if you're going to be telling stories about me, I think I'm going to go" Sean smirks pulling on his jacket which he had taken off and hung over the chair.

"Oh no you're not" Aaron grins putting his arm tightly around his brothers shoulders and forcing him down on his seat "You're staying for this, and I'll take you out for dinner afterwards okay?"

"Are you seriously trying to get me to let you tell the story with a promise of dinner afterwards?"

"Oh no, I'm telling it either way, I just thought you were looking quite thin"

"Stuff you Aaron" Sean sighs but grins

"Anyway so it was summer in New York, absolutely boiling outside and we were having a BBQ at our dad's friend's house…."Hotch begins

*14 years ago*

"I wouldn't drink so fast Sean, you're going to need to use the bathroom and there's a massive queue" Aaron warns his brother. The Dunphy's only had one bathroom and there was a lot of people at the BBQ.

"Shut up Aaron" Sean replies. At the age of 6 he was dead set on doing the exact opposite of what his brother told him to. Which Aaron found incredibly annoying.

"You'll regret not listening to me" Aaron sighs jabbing his brother in the ribs before walking off to find Jimmy who was at the BBQ as well.

It was only about half an hour later when Aaron felt his brother pulling at his shirt sleeve.

"What is it Sean?"

"Aaron, I need to go for a wee-wee" Sean looks up at his brother holding his trousers around the groin in desperation.

"You should've listened to me, go wait in the queue"

"I can't wait" Sean moans. Aaron now had two choices he could be a good big brother and walk Sean the short distance back to their house so he could use the bathroom or he could….

"Bet you wished you listened to me now" Aaron smirks at his brother poking him in the ribs causing him to laugh and move away "Aaron! Get off!" He squirms but his brother carries on to tickle him making Sean giggle uncontrollably and before you knew it…his trousers started to become wet…

"Ew Sean! Mum! Sean wet himself!" Aaron shouts so everyone at the party could hear

"Aaron made me do it mummy!" Sean runs off crying whilst holding his now wet pants so they didn't fall down.

"We had to leave then because mum and dad were embarrassed as well" Aaron laughs but he was the only one laughing.

"Hotch, that wasn't funny, that was just harsh, he's your little brother" Emily looks at her boss disapprovingly

"So you find his story funny but mine is harsh?" Aaron looks at them in disbelief

"Yes, poor Sean, I don't know how you coped with him as a big brother" JJ looks at him sympathetically

"Well it was hard, but I coped" Sean smirks receiving a glare from his brother

"Shut it Sean" Aaron orders jabbing his brother in the ribs

"That's not going to work this time bro" Sean winks

"Shall we test it?" Aaron eyes his brother

"No that's alright, anyway where's that dinner you promised me?"

"Come on then" Aaron sighs standing up and guiding his brother to the exit

"See you guys tomorrow" Hotch smiles at his team

"Bye Hotch, It was nice to meet you Sean, come again soon" JJ shouts after them

"Never come again" Hotch turns to his brother whilst they were in the elevator

"Oh bro, trust me I'll be coming again" Sean says before his brother begins to jab him in the ribs making him laugh. Sean tries to pull away and succeeds. He moves his hands in mock fighting position "Not again"

"Seany, one day I'm going to kill you" Aaron smirks at his little brother.
