A/N: This is an idea that has been in my head for forever but I've been too busy to write it until now. Anyway AU. No particular timeline but Jason just left, Hailey and Hotch are divorced, Prentiss just joined, and Garcia isn't with Kevin and Seaver isn't there but Rossi is though he just got there as well. No pairings.
It was around 7:30 when Aaron Hotchner strode into the bullpen in his usual suit. He assumed he was the first one to arrive judging by the empty bullpen but then again J.J and Dave could both be in their offices. He was heading for his office when Rossi stopped him.
"Hey Aaron you got a minute?" The Italian asked, holding a case file.
"Sure Dave." Hotch said as the two began to walk to his office. "What's up?"
"There's this case from about five years ago that one of the victim's family asked me to look into." Dave explained.
Hotch nodded, his face its usual stoic mask as he opened his office door and turned on the light. Both men stopped dead in their tracks when they spotted a young man sprawled out on Hotch's couch. Dave's face held confusion and he looked to Hotch for an explanation. The Unit Chief in turn kept his face expressionless as he moved to the unconscious man.
"Spencer?" Hotch said as he gently shook the sleeping figure. The young man in turn jerked before his long eyelashes fluttered open.
"Aaron?" The question came accompanied with a yawn a sat up and stretched. Only then did Rossi take in his full appearance. The kid seemed young with chestnut brown hair and matching eyes. But what was shocking was his clothing choice. Spencer was wearing incredibly short jean shorts with a tank top. His hair was slightly mussed from sleep.
"It's about time you got here!" Spencer exclaimed, now fully awake, his voice slightly high-pitched. At seeing Hotch's confused expression he continued.
"Don't tell me you forgot about me?" Spencer pouted slightly. The young man fixed Hotch with an upset glare but really he resembled an indignant kitten.
"What are you talking about?" Hotch asked carefully. Rossi noticed the way Hotch talked to Spencer; it was the same calm way he talked to UnSub when he wanted to prevent them from doing anything drastic.
"You called me yesterday and told me you were wrapping up case but you would be back by ten and you had something to tell me. So I came and I waited and I guess I fell asleep. I missed an entire night's work and last night's episode of Doctor Who!" Spencer reminded him animatedly.
"Oh our flight got laid over and by then it was after one and I completely forgot. I'm really sorry. I should have called." Hotch apologized. Now Dave was really confused. Who was this young boy dressed like that? And how did he know Hotch?
"It's okay. I'm used to being forgotten." It was meant to be taken jokingly but there was the smallest ting of pain in his voice. Hotch put an on his shoulder apologetically, giving it a small squeeze. After a moment, Dave cleared his throat making his presence known.
"Oh hi I didn't see you there. I'm spencer. Oh I love the outfit by the way." Spencer perked up and introduced himself to the Italian. "You're David Rossi aren't you?"
"Yeah how did you know who I was?" Dave asked sounding surprised. Spencer shifted uncomfortably.
"I uhh try to read a lot." The young man answered. He noticed the file Rossi was holding. "Well I better get going. You must have work to do." The young man moved to leave.
"Wait spencer I still haven't told you." Hotch moved to stop him.
"You know you can just call me right?" Spencer smiled.
"It's better if I tell you in person." The profiler said, his stoic mask coming back into play. Spencer cocked his head to the side wondering what was so important that Hotch couldn't tell him over the phone. Both men watched as a slow seductive smile spread across Spencer's face.
"I'm not in trouble am I?" He asked huskily.
"Spencer…" Hotch said in exasperation.
"Okay, okay I'm going." Spencer grumbled good-naturedly. He exited the office and was met with the bullpen. It was still early and there were only a few people there. Some stared but didn't say anything. He realized how weird he probably looked in a government building wearing his "work" clothes.
"Hey Pretty Boy!" Derek bellowed across the bullpen. Spencer rolled his eyes at the nickname with a smile. He didn't mind Derek calling him that but of course he would never tell the dark-skinned profiler that. From her desk Emily Prentiss-the latest edition to the BAU-watched as young man walked toward Derek's desk.
"Hey Derek." He greeted.
"Pretty Boy why didn't you tell me you were coming. You know Penelope would flip out if you were here and she didn't get a chance to see you." Morgan reminded him.
"Sorry but it was unplanned honestly. Aaron wanted to tell me something yesterday but you guys were tied up in the airport or something. I kinda fell asleep here." Spencer said sounding slightly chagrined. Emily perked up at the use of her boss's first name. Who was this kid? Why was he dressed like that? And how did he know Hotch?
"This" Morgan said gesturing to Prentiss. "This is Emily Prentiss. She's a member of the team now."
"It's nice to meet you I'm Spencer…Spencer Reid." The two shook hands.
"So how do you know Hotch and Morgan?" Emily asked curiously.
"I know everyone in the BAU. Well except you and Agent Rossi. But yeah I know Pen, Derek, Aaron and J.J. Jason actually introduced me to everyone awhile back."
"Jason? As in Gideon?" Emily asked trying to mask her disbelief.
"Yep that's him. Speaking of Jason, where is he?" Spencer asked looking around the bullpen. Derek considered what to say. It would crush Spencer to hear Gideon had been MIA for a while. A small lie couldn't hurt right?
"Actually he took the day off." Morgan said, ignoring the confused look Emily shot him.
"Oh I guess I'll call him later then. I better get going, if Darius doesn't know where I am he'll freak." Spencer said casually.
"Okay I'll let you go but on one condition."
Spencer merely raised a questioning eyebrow.
"You have to come back tomorrow." Morgan demanded.
"Don't tell me you're busy." The profiler stopped his protest before he could make one. "You work at night and we don't have any cases so Hotch won't mind and you said he has something to tell you."
Spencer sighed in an almost defeated way before a flirty smile appeared on his lips.
"Only because my favorite person works here." Spencer called over his shoulder as he walked away.
"Aww you're too kind." Derek called after him.
"I was talking about Penelope." The young man called without turning around. Emily laughed as the door closed behind the flamboyant creature that was Spencer Reid.
A/N: Just a small idea that popped into my head. Please rate and review.
