A/N: Hello, lovely readers! I think I'm going to be focusing on this story for a while. Next chapter will probably focus on the Winchesters, who I have never written for before, so bear with me.

Reid sat at his desk, going over his paperwork and smiling. Morgan looked up at him and frowned. Reid had been acting… strange lately. When he looked like he was about to burst out laughing, like he was now, something bad happened. It was freaking him out.

"What's so funny?" Morgan asked lightly. Reid looked up.

"Does something have to be funny for me to be smiling?" It was said in such a sickly sweet tone of voice, he could have thought Reid sounded like an angel. But the context and his inflection made him sound almost like a demon. Morgan recoiled slightly.

"I mean, kinda." He mumbled. Reid's head snapped up and he looked at Morgan a moment, no longer smiling.

"I disagree." He said, barely controlled temper boiling just below the surface audible in the seemingly innocent words. That was another thing Morgan had noticed was different. His temper was always out of control, he would be fine one minute and passive-aggressively snapping at you the next. It wasn't like when he was on drugs- that was Reid, just really irritable. No, this was completely different. He wasn't even acting like himself. No rambling random facts, no social awkwardness, short temper, morbid comments, less focused on work, he was like a completely different person!

His fashion sense had even changed. He now wore dark clothes that complemented his physique, he wore his sleeves rolled up, he wore jeans every once in a while, and he now had a leather jacket. He seemed to start working out, being much more fit than ever. He had even run faster than Morgan the other day, just to prove he could! And he was cocky too. He cut off his long hair and styled it. It was too strange. JJ walked by the pair, moving slightly further from Reid than she normally would. The whole team had noticed the change.

"We've got a case." She said and hurried away. Reid smiled after her- that creepy smile.

"We've got a case!" He imitated her voice, shocking Morgan once more. Before Morgan could comment, Reid finger gunned at him and spun in his chair before hopping up. He walked confidently to the briefing room. Morgan just stared after him for a moment before getting up and following him. He walked into the briefing room to see Reid standing next to Prentiss, who was sitting in an office chair. She looked somewhere between angry and uncomfortable. As Morgan walked into earshot, he understood why.

"I said, no thanks." She growled.

"Cmon', baby. You haven't even thought about it." He said.

"Reid, what are you doing, man?" Morgan asked as he approached. Prentiss looked grateful.

"I'm just asking Prentiss if she wanted to go to dinner," Reid said a lopsided smile on his face.

"'Asking' is a stretch," Prentiss muttered and Reid's jaw clenched. At that moment, Hotch walked in. Everyone took their seats and Garcia stood in front of them.

"We have women being killed in New York City," Garcia began. "All strangled in their own homes." Morgan had feeling this was going to be a long case.

…

"... Why strangulation?" Prentiss was asking as she tried to ignore how much she looked like all the victims. They were on the jet, bouncing ideas around. Reid was still throwing off that creepy vibe he had been for about two weeks now. She found out he drove a motorcycle the other day. Since when did he do that?

"Maybe he likes to watch the life leave their eyes." Speak of the devil. Reid said it without any of the disgust he would have two weeks ago. Instead, he sounded uncharacteristically… fascinated. She resisted the urge to shudder as he met her eyes. His eyes, previously full of curiosity and warmth, now looked cold and… she didn't know how to describe it. His eyes reminded her of a psychopath's. He looked away as Hotch began talking. She noticed that every time he looked at Hotch, he looked like a predator. Like a snake you didn't know was there until it was too late. Same with Morgan, and every other alpha male he encountered. It made her feel terrible thinking of one of her best friends like this, but he wasn't acting like her best friend. He was acting like a highly functioning psychopath. And that scared her.

…

JJ sat as far from Reid as she could at the police station. The rest of the team had gone out to look at the crime scenes and the coroner. Leaving her alone at the station with Him. She refused to think of him as Reid. Not her Reid. He was just so different. She saw the look in his eyes when he looked at crime scene photos. She heard the comments he made when he thought no one was listening. She remembered how absolutely disgusted he looked when anyone mentioned children. Before she had noticed the more severe changes, she had suggested that he come and play with Henry. Where there was normally adoration and love on his face when the subject of his godson came up, there was hatred and loathing that she couldn't fathom at the time. He, of course, rejected the suggestion. That was when the more drastic changes came about and she began to avoid him. But now she was stuck at the station. With Him. Her least favorite place to be.
