Merry Christmas! So, here we have the fight between JJ and Reid. I consider having Reid be an asshole, but decided that he could be a little more cruel than JJ, so I nixed it, letting JJ dominate the right. Alas, since I'm a romantic at heart, it does cool down at the end. Tiny bit of langauge in here.

Hope everyone had a great christmas!

And a very merry christmas to whatif-ifonly!

I don't own CM, please read and review.

Derek Morgan blew out a breath as he slung his bag over his shoulder. It had been way too quiet on the plane ride home, especially considering how the case had ended. Reid had said over and over that he was fine, but he wasn't, anyone of them could tell. Seaver kept looking at him from her seat across the aisle, and he was sure that Emily had been talking to Penelope about Reid. Kid had been a mess the entire case and Morgan was glad they were home. Hotch and Rossi had taken a separate elevator (to talk about Reid probably), so he, Emily, and Reid piled into the elevator, Reid keeping his distance especially. Seaver had been trying to have a conversation with him, but gave up and was talking to Emily as they exited and headed towards their desk.

Morgan pulled open the door, asking Reid, "Hey youngster, you want to grab a bite to eat?" Spencer adjusted his bag on his shoulder, considering the older agent's offer. "Uh, thanks Morgan, but I'm not very-" He stopped midsentence as well as mid-step. Morgan stopped just before he ran into him, but Emily wasn't so quick, smacking into Morgan's back. She peered around Morgan's large frame and paled when she saw what had caused the genius to grow quiet. "-hungry." Spencer finished his voice flat, with a twinge of fear and annoyance.

Standing right in front of his desk, her stance one of offense as well as defense, arms crossed and a glare on her beautiful features, stood a very unhappy JJ. Spencer looked at her for a long moment, which Emily decided was the right time to try and sneak away. Unfortunately, Spencer caught the movement out of his peripheral vision. He immediately rounded on her, a look of betrayal on his features. "What are you looking at me for? I didn't call her!" Which was the truth, considering JJ was already there when Emily had called.

"Don't get mad at Emily. She didn't force you to take your vest off or confront the unsub!" JJ said hotly, marching over to the young genius. "JJ, can we not do this here?" Spencer asked, annoyed that he was now having to get a down-dressing after an already terrible weekend. "You want privacy? Fine, the conference room is open." She informed him, spinning on her heel and marching over to the steps, Reid following her. Hopefully she would run out of steam quickly so he could go home and sleep off his headache.

"What the hell were you thinking, Reid? That the unsub was going to surrender quietly?"

"No! I'm not that stupid, JJ."

"Well, you could've fooled me!"

Emily winced, taking the bag of popcorn Garcia was offering. They were sitting at Emily's desk, Garcia having taken Spencer's chair. Seaver had left as soon as she could and Morgan was sitting at his desk, finishing his paperwork while listening to the argument JJ and Reid were having. Well, it was really more JJ yelling at Spencer than anything.

"What's that supposed to mean?"

"It means that for a genius, you make a lot of stupid decisions."

"That's not true!"

"Oh, really?"

"Oh, he set himself up for that." Garcia said around her mouthful of popcorn. "True, plus she's got so many examples to choose from. Emily agreed. "Hey, Morgan, can you please go get us some drinks?" Derek looked over to her. She pushed her lower lip out into a pout. "Please."

"Oh well, please, by all means, enlighten me." Spencer growled his hands planted firmly on the table as he glared at JJ.

"Okay, how about when you confronted Owen Savage without a vest or a gun?"

"I was the only one who could stop him!"

"Oh, yes, because only the great Dr. Spencer Reid could save us all!" She said sarcastically, throwing up her hands.

"That's not true, and you know it!" He hissed, remembering Adam Jackson.

"Alright, fine, let's talk about unnecessarily putting yourself in danger."

"What-"

"Trapping yourself in a room full of anthrax."

"I didn't know until I entered the room! You know what? Let's talk about you, JJ! You're not innocent either!"

"Oh, this is gonna be good." Morgan commented, handing the ladies the drinks he got from the vending machine. Hotch had disappeared into his office after seeing who was in the conference room, and Rossi had already left. "I don't know. JJ doesn't really put herself in trouble." Garcia mused. Emily nodded.

"Oh, yeah, go on, Reid. Tell me what a troublemaker I am." JJ mocked and Reid clenched his fists.

"How many times have you wandered off by yourself and gotten into trouble?"

"Not as much as you have!"

"No, because you get to stay behind in the station while the rest of us put our lives on the line!" He snarled. JJ moved so quick, Spencer almost didn't catch it. She shoved him as hard as she could into the window, ignoring the clunk sound that sounded when the back of his head connected with the glass. "How dare you! Like I'm not in the field just as much as the rest of the team! Like I don't put my own goddamn life on the line!" She shouted, her face growing red with anger.

"Oh ho!" Garcia cried.

"Ouch!" Morgan winced.

"He deserved it." Emily stated.

The three agents still in the bullpen were now on their feet. "Should we step in or something?" Garcia fretted, wringing her hands together. "Not just yet. Reid's lucky if she doesn't punch him." Emily scoffed.

Normally, a hit like that wouldn't have hurt Reid as much, but combined with the pounding headache, it caused him to double over, grasp his head and groan.

"Reid?" JJ felt bad when she saw his feature contort in pain. She didn't even push him that hard… had she? She moved closer to him, touching his shoulder. "Spencer?" She asked, lowering her voice, and he sighed. "It's nothing, I'm fine." He slowly rose to his normal height, ready to continue their fight, but JJ's anger was gone in light of his pain. "Are you having a headache?"

He looked at her, surprised. "How did you?"

"I was in the office with Garcia when Emily called. She said you get really bad headaches." Spencer was quiet more nodding slowly. JJ grasped his arm and led him over to the table, and he sat on the edge. She reached up and gently placed her fingertips on his temples, gently rubbing small circles.

"What the hell? They were just fighting." Morgan complained. "Looks like Reid is having another headache." Emily sighed. "I'm sure the blow to the head didn't help," Garcia mentioned. "Probably done fighting now." Morgan sighed, closing his file and standing up, stretching. "Well, that was short lived.

"How long have you been having these headaches?" JJ questioned softly, standing in front of him.

"I've had this one for about two days, but they started about a week ago."

"Are they regular headaches?"

"No. The light hurts my eyes and I'm sensitive to loud noises."

JJ chewed on her bottom lip, feeling guilty for yelling at him. "Have you gone to see a doctor yet?"

"Yeah, I had an appointment before we leave for the case. They should have my results tomorrow." Spencer studied her quietly. Now that she was done yelling, he was feeling better. Although, her gentle ministrations may have had something to do with that. He reached out and took her hand, suddenly feeling vulnerable. "JJ, what if there's something wrong with me? Seriously wrong?"

"Hey, you're going to be fine. The doctor will tell you it's probably just bad migraines brought on by stress or something." She was quick to assure him, moving forward and hugging him tightly. He sighed and bowed his head, burying his face in her neck.

"I hope you're right."
