"You're weak." Merissa taunted, towering over Serena's limp body on the wooden chair. She slapped her, and Serena whined out in agony. "I can't believe I spent all my fucking energy trying to capture you, when you just came right to me. You're nothing but a little piece of shit. How stupid are you?" She delivered another blow.

Two days ago

"Serena wants to join us in the field. She's arriving very soon." Hotch announced to the team. They were all relieved; they had been grappling at this case for a week, but no success. Garcia couldn't track down the mysterious Adam Gomez, and more and more girls were being raped and killed. The whole state of New York was on edge. Hardly any East Asian girls walked the streets anymore. They could definitely use a fresh pair of eyes.

"Well, I hope she's got something going inside her brilliant brain, because we got nothin'." Morgan said, throwing his hands up in frustration. The team was gathered around the table, the victims' pictures plastered on the board.

"Well, let's not just sit around and do nothing." Prentiss stood up. "What do we know?"

"Literally nothing." Reid replied. Prentiss and the team stared at him. If the genius doctor with an IQ of 187 didn't know anything about the case, then… "Fine. We know these victims are surrogates. Like how Bundy initially killed women that looked like his ex. He probably had a breakup with a woman who looks like the victims. But these are supposed to be rage kills. He's supposed to be unleashing all his anger on them. Which classifies him as a disorganized killer. But all the crime scenes point to an organized offender. It just doesn't fit. The most recent victim, Alexa Soon, she wasn't raped. Which means he's deviating from his ritual. He's devolving."

"I'd say you guys have a lot more than nothing." Serena remarked, standing at the doorway. The team welcomed her warmly.

"Thank god you're here, Serena." Prentiss said, embracing her friend. "We've pretty much hit a dead end."

Hotch eyed Serena suspiciously. Her sudden reappearance was troubling for him. He was going to keep an eye on the youngest member from now on. They didn't need a whole repeat of the Elle fiasco.

"I hate to break up the reunion, but we have a job to do." Hotch said sternly. The team members nodded. "JJ, talk to the victim's families. See if they have some connection that we missed initially. Reid and Serena, work on victimology over here. Contact with Garcia and JJ. Morgan, Rossi, Prentiss, visit the crime scenes. I'll talk with the detectives." The team got to their posts and began to work.

Serena took a look at all the victims' photos, and narrowed her eyes. "Reid, are the victims-"

"Surrogates? Yeah, we think so. Probably had a breakup or something. You know, like Bundy." He responded, looking at the autopsy reports.

"Damn." Serena muttered. Merissa was really angry. So many girls, all because of her. It didn't feel right. She had to tell Reid. "I know who the unsub is." She blurted out. Reid gave her a stare.

"You-who?!" He exclaimed, shaking Serena.

"You already know her. In fact, the entire team does. Lady X." Reid gave her a weird look.

"But, Lady X has been killing for years. Why start killing for a surrogate now?"

"Maybe she had a victim who...got away." Serena offered, and left the room, leaving Reid alone.

Serena slipped out of the police station, and began to wander the streets. They were all somewhat similar; she had spent most of her childhood here, after all. She suddenly heard loud shouts in the distance.

"KY KY!" A figure in a blue dress jumped onto another's back. Serena smiled. Alayla. She walked up to the two figures. The one who had screamed was smiling widely. Her strawberry earrings shone in the afternoon sun. Her black curly hair was pulleed into a bun. The other was a complete contrast. She wore a grey sweatshirt, and her hair was dyed pink. She looked tired, like she had pulled an all-nighter.

"Hi, Serena!" Alayla said.

"I thought you were hiding from the Merissa bitch." Kylee muttered.

Serena looked around. "Yeah, I was. But my team has a case here. And, I think it's Merissa killing again." Alayla's eyes filled with worry.

"Yeah, we saw that FBI agent on tv! Have you told the police it's Merissa?" Alayla asked, excited. Kylee scoffed.

"You think she'd want to? To be honest, I'd take down the bitch myself. No police needed." Her girlfriend said, cracking her knuckles. Alayla looked at Serena.

"Did you? Please say you did."

"I told one of my team members. He's smart, he'll figure it out." Serena replied solemnly. Kylee shrugged and began playing with her hair again. It was a common habit of hers. Alayla smiled weakly.

"Promise me you'll be okay, Serena." She embraced Serena in a tight hug. Alayla tried to get Kylee in the hug as well, but Kylee edged away.

"I need to get back to the station. No more girls have to get killed." Serena said defiantly, and ran back to the police station.

"She's so brave…" Alayla gushed, staring after her friend.

"Meh." Kylee shrugged.

"The office of everything known and unknown, speak." Garcia's voice rang from the phone.

"Listen, Garcia. I need you to pull up some files on someone." Reid said.

"Seriously, Junior G-man. You've worked with me for like what 6 years and you still- ugh, nevermind. Who do you need?"

"Lady X." Reid answered.

"That woman. Ah. I have to say, Lady X is such a cool name. Do you think it means something? Like-"

"Garcia!"

"Right, right, sorry. Let's see…well her first recorded kills that we know of started...dang. 17 years. She is a pro. She killed mainly young girls...most of them were 18. I guess she has a type. Uses a gun and a knife. But there's literally no record of her killing surrogates. Still, she is a mad woman, I tell you."

"Thanks Garcia." Reid said.

"Of course. Tell my Chocolate Thunder I need to hear his voice, please."

"I-yes, fine." The doctor rolled his eyes and hung up.

What the hell? Why would Serena say it's Lady X? What kind of proof does she even have? How would she even know- oh. Reid stopped in his tracks. It could be possible that Serena was a victim who-got away. And now, Lady X was angry and kept killing surrogates for Serena. All the victims, they had similar features to Serena. Hotch, Rossi, Prentiss, and Morgan stepped into the room.

"Garcia wants to talk to you." Reid muttered to Morgan. The man gave the genius a weird look, and called the technical analyst.

"Reid, what's wrong?" Prentiss asked.

"Serena knows the unsub." Reid replied. Morgan turned his head, phone pressed twoards his ear. All four of them stared at Reid.

"Who is it?" Hotch asked, regaining his composure.

"Lady X." Reid replied.

"The hitwoman who has killed more than a hundred victims, and evaded law enforcement for at least 17 years?" Rossi exclaimed.

"Yeah. And I think Serena's gone to find her." Reid said.
