SISTER ACT

"Please, stop. Just stop." Jackson Thomas pleaded with the figure standing above him. Those few words earned him another few seconds of relentless punches and kicks aimed primarily at his face. He tried to turn his body to avoid the blows, but his attacker seemed to be everywhere. He couldn't even use his hands to shield himself; they were cuffed tightly behind his back, as they had been since he'd woken up in this room thirteen hours before. In those thirteen hours his attacker had beaten him unconscious twice using various methods, including what Jackson thought to be a taser, judging by the way his body was shaking after he woke up.

But in between the beatings, his attacker asked him about his brother, Robert. His attacker was interested in their relationship; how they got along, what annoyed him, what made him angry. Jackson didn't understand the reasoning behind the questions, he was just happy for the break from the physical pain. Now however, his attacker seemed to be more focused on the pain rather than Jackson's past.

After a few more well-aimed punches, the attacker relented for a second, peering down at his hostage with a look of borderline amusement.

"You can stop this anytime you want, Jackson."

Jackson grimaced, his attacker had been saying this every few hours, asking the same question: "Do you want me to call your brother?"

Now, as his attacker said it again, Jackson mulled it over. He'd said no all the other times, not wanting to get Robert involved in this. His attacker regarded him for a moment, and then spoke again.

"I asked you if you wanted me to call your brother. One call to him, and this can all be over, Jackson. Robert can come get you, and this will all be over." Not getting a response from Jackson, the attacker spoke again. "Come on Jackson, all it takes is one phone call. One phone call and this will all be over."

Finally, Jackson spoke, his voice hoarse and shaky. "Yes. I want my brother to come get me."

His attacker smiled; this really was much too easy. The attacker retrieved Jackson's phone from where it had been placed earlier and pressed number 1 on the speed dial. Putting the phone on speaker, the attacker set it back down. After only three rings, the attacker and Jackson heard Robert's panic filled voice.

"Jackson? Jackson, are you okay?"

His attacker prompted him. "Go ahead. Ask him to come get you. Tell him you need him."

Jackson did so. "Robert, I need you to come get me."

"Jackson, where are you? Where do I go?"

The attacker spoke again and gave an address. "Look forward to meeting you." The attacker finished the conversation and hung up the phone.

Jackson spoke, pleading. "Please, don't hurt Robert. He didn't do anything." Jackson was so focused on his pleading that he didn't realize that his attacker had pulled out the baseball bat Jackson had been beaten with earlier. Jackson didn't even realize what was going on until after he'd been hit in the head. And then Jackson knew. He knew he was going to die, and he knew that he'd brought his brother down with him.

By 5:00 the next morning, Anna had already showered, gotten dressed, and was now sipping her first cup of coffee. Flipping through the mail, she came across a blank envelope with absolutely nothing written on it. Her hand started shaking immediately; she knew what was inside. Setting her coffee down gently, she gently tore open the envelope. It held two pictures, both of men. One appeared to have been badly beaten, and the other had been shot several times in the upper torso; it was just like the other ones. And, like the others, there was also a note. She didn't need to even look at it to know what it said.

Your time is coming.

It was typed in basic black font, and Anna already knew that the police wouldn't be able to get any prints off of it. They hadn't gotten any prints off of any of the letters. Each of the twelve envelopes she'd received had been clean for both prints and saliva. Anna was sick of hearing that the police couldn't help her. So, she decided it was time to use her last resort. Knowing that even at this hour she would already be awake, Anna dialed the familiar number, feeling an unnerving sense of relief when she heard the voice on the other end of the line pick up.

"Prentiss."

"Emily? It's me. I need your help."

"Yeah, I got it. I'll present it to the team now. Yes. See you soon." JJ hung up the phone and leaned back in her chair thinking about the phone call she'd just received. It was safe to say that it was one of the last conversations she'd ever expected to have. Standing, she grabbed the pad of paper she'd written on during the phone call and stepped out of her office. Catching Morgan's eye, she tilted her head toward the conference room and began to walk that way herself, knocking on the doors of Hotch and Rossi's respective offices along the way. Less than three minutes later, everyone was settled around the wooden table, including Garcia, who'd been summoned by a hastily sent text from JJ's phone.

"Where's Emily?" Morgan asked, voicing the question on almost everyone's mind.

Hotch answered. "She asked for a few days off." This immediately sparked interest, Emily Prentiss never took days off unless she was forced to by the department. These questions were temporarily put aside, however, as JJ began the debriefing.

"I just got a call about a series of double homicides. The victims vary in age, race, and gender. The pairings of the victims are varied as well; there have been pairs of males, pairs of females, and pairings involving a male and a female." JJ paused and Rossi spoke.

"Is there any connection between the victims?"

"Well, not between the various pairings, but each set of victims are siblings." She listed of multiple sets of names, ending with Jackson and Robert Thomas. As she spoke, pictures popped up on the screen behind her; the same pictures that had been sent to Anna Prentiss, though the team didn't know that.

"Twelve sets of victims?" Reid spoke now. "Why weren't we called in sooner?"

"Because," JJ answered, "the victims have been scattered throughout different cities all across the country."

"Okay, so, who called us in?" Morgan asked.

"Well, it's more of a personal favor; there hasn't actually been an official request, but I'm working on it." JJ was hedging now, and in a room full of profilers, it showed.

"JJ, what's going on?" Hotch asked. It wasn't like her to not follow procedure.

"The killer has been making contact after each set of killings. He's targeting one woman in particular." JJ hesitated for only a moment before clicking a button on the remote she held. Another picture popped up on the screen, this one of a beautiful, smiling woman who appeared to be in her late twenties. That however, is not the first thing the team noticed. What they noticed first was this woman's uncanny resemblance to their very own Emily Prentiss.

Hotch spoke again. "JJ, what is going on?"

JJ talked, faster now, trying to get all the information out in the right order. "This is Anna Prentiss, Emily's younger sister. Every week for the last three months, she's received an unmarked envelope with pictures of each of the victims and a note telling her that her time is coming. The locals couldn't get any prints or saliva off of any of the envelopes, and they're so backlogged that facial recognition took awhile. They thought it was a hoax until the fourth victim, but between a lack of cooperation between departments and backups in the labs, they haven't been very on top of things." JJ paused before continuing. "That's where Emily is. Her sister called her yesterday morning and asked her for help. Emily called me when she realized the extent of what she was dealing with. She wants us to come too."

"Where does her sister live?" Reid asked.

"About an hour and a half from here." JJ answered. "I spoke to the chief of detectives, and he said he would be willing to accept our help." She waited for a response.

Hotch and Rossi's eyes met, and Rossi nodded very slightly. Hotch then spoke to the rest of the team. "We'll leave in ten minutes. Meet in the garage."

The team stood without another word, gathering their files, mulling over the fact that Emily had a sister she never told them about.
