After getting settled on the jet, the team gathered and began to discussing this case. The unsub was kidnapping these young women and murdering them after some time in captivity. The latest victim, Riley O'Connor was murdered within a week of being abducted. Knowing that the time has sped up between victims, the Colorado police called in the BAU.

"Okay, So the latest victim, Riley O'Connor was on her way home from work when she was abducted. She was last seen at a grocery store but hasn't been seen since then." Morgan said as he looked up from the case file.

"Ella Montgomery, Melanie Thompson and Ruby Franklinson were all murdered within 4 weeks of each other and now Riley, was abducted and murdered within a week of the last victim. He's excelerating. " Reid stated

"Something obviously set him off if it is just a single individual. I.." JJ was cut off

"There's a pattern between these victims, besides the fact that they looked a lot alike, but Garcia sent me a background of all the victims and all 4 women, by the time there were 13, all of their mothers had been murdered."

"Do we know who had killed these women?" Rossi asked looking at Reid

"Yes, Robert Flynn was convicted in 2008, 2 years after their bodies were found."

"Where is he now? " JJ asked

"He died last year."

"Well thats not gonna help;" Derek said

"We just have to figure out why this guy is going after the children of the Victims, and what his connection with Robert Flynn is. There's another connection, we just haven't found it yet. " Hotch stated

Pulling out her phone, Emily sent a message to Marissa and let her know that she wouldn't be home in the next couple of days. Marissa understood and let Emily know that she would explain it to Natalia. Emily was grateful for Marissa, she didn't know what she would do without her.

When the plane landed and they arrived at the precinct, they were lead into a conference room by one of the other officers. The room was small but has a glass white board. Before the team got situated, a man walked into the room.

"Good Afternoon, you guys must the BAU. My name is Michael, I'm the sheriff. "

"Thanks for calling us in Sheriff. Im Aaron Hotchner, Unit Chief and this is my team, SSA Derek Morgan, David Rossi, Doctor Spencer Reid, Jennifer Jareau, and the newest Emily Prentiss. We also have our technical analyst back in Quantico on speed dial. "

"Nice to meet ya'll."

"What do you know about this unsub?" Hotch was quick to add

"We're starting to think that this is one individual."

"How do you know" Hotch asked

"the coroner was preforming an autopsy and all 4 women had the same marks. Multiple people couldn't make the same marks in the same place every time"

"What kind of marks?"

"It's almost like a burn mark. At first she thought that it may have been marker but when she tried to wipe it off with a solution, it wouldn't come off. Her solution was a burn mark or a makeshift brand " he handed the team autopsy photos.

" Okay, Derek and Rossi I want you both to go and speak with the coroner. Reid and I will go to the last crime scene and JJ and Emily, I want you both to stay here and wait for Riley's family. They should be arriving soon. "

As the team dispersed, Emily and JJ waited for the family to arrive. Emily was going over paperwork and JJ was trying to get in contact with some of the other family's when there was a knock at the door. They looked up and saw Sheriff Michael standing there.

"Riley O'Connor's parents are here. Do you want to speak with them here or we have a different room?"

" A different room would be great. I don't think seeing pictures of their dead daughter would make them feel any better." JJ snapped

"I agree."

Meanwhile, Hotch and Reid were at the crime scene hopeful for some more clues.

"Although she was restrained, she tried to fight him. She has ligature marks on both her wrists and ankles. She also has a star on her chest just like the others. " Hotch asked leaning over and pulling some of the fabric down

"You know having a star tattoo has many meanings. For some people it could represent guidance, dreams, freedom, light, and ambition. What if this Unsub gets a feeling of freedom after killing these woman?"

"It's possible. He could be feeling the weight of Flynn's killing's and by killing the victim's children, he could be getting a rush of freedom.

"We need to look into Flynn's past a little more."

"I agree, I'll call Garcia."

Morgan and Rossi were at the coroners office talking to the coroner and examining the other three victims.

"Hello, I'm Derek Morgan and this is my Partner, David Rossi , we're part of the FBI and we're looking into the murder of these women."

"Nice to meet you both. Is there anything I can help you with."

"Yeah. All the victims all died of different causes but they all had the same signature?"

"Yes, Ella Montgomery had several stab wounds which led to her cause of death, Melanie Thompson had a gun shot wound to the chest, and then Ruby Franklinson was strangled. You can tell by the ligature marks around her throat. But when I was preforming the autopsy, I found that each victim had a small star tattooed onto their chest. I thought maybe the first one was a personal Tattoo but I after I seen all these women had the same mark, it was a little suspicious to me. "

"Rossi, this is weird right? I mean all of these women were killed in different ways and yet they all have the same signature. This has to be one person right?"

"Im starting to think so. But we still need to figure out why he's killing in different ways."

Back at the Precinct, JJ and Emily have spent the last hour speaking with the victims families.

"I feel bad for all of these women, to have your mother killed when you're 13 and then your own life taken years later. They had their whole life ahead of them" Emily placed a hand on JJ's shoulder.

"I know. I feel the same way but we need to get this man off the street before he finds someone else. "

When the team finally all joined back together, the team had shared what they gathered.

"Talk to me." Garcia stated

"Garcia, Please pull up Robert Flynn for me. "

"Okay."

"Now search if he had any children or any other close family members."

"Negative on the children and it seems that he didn't have any close family members. "

"Okay what about relationships?" Emily asked

"Mmmm. His last girlfriend, Jessica Miller had a 9 year old son at the time. His name is Mason Skylar . From what I can tell, his last address was listed a few years ago. He doesn't have a job listed. "

"Okay. Can you give us his last known address? " Hotch asked

"Yes. Should be sent to your phones any minute now. "

"Thanks Garcia" Hotch stated and then hung up the phone. "Let's go" Hotch stated standing up and heading out the door. The team followed him.

When they arrived at the house, Hotch and JJ walked to the front door while the others stayed back watching, in case he or anyone decided to make a run for it.

After a few attempts, there was no answer. There seemed to be no movement in the house. Outside of the house, it was old, rundown, almost looked like someone hasn't lived there in years. After one last knock, both JJ and Hotch turn and head back to the car.

After gathering and heading back to the precinct. It was getting late. The sun had started to set. They were running off a few hours of sleep and no food.

"Hey everyone, Mason Skylar is someone of interest. We need to find out everything about him. I've already called Garcia. It can wait until the morning though. We need to get some rest and eat something. I know you guys must be starving. So please. Head to the hotel and we shall meet up in the morning." The team agreed and headed back out of the door.

Emily called Marissa when they got to the hotel. Natalia asked when she was coming home and she had to be honest and tell her that she didn't know when she was going to come home. Emily's heart broke when she heard Natalia start to cry on the phone.

"Im sorry baby. I'll be home as soon as I can. I love you so much."

"I love you too mommy." She said as she sniffled.

"Alright go to sleep and I'll be home before you know it. Sweet dreams Talia."

"Goodnight mommy. I'll see you soon."

"I'll see you soon Talia."

When Emily hung up the phone, she looked over at JJ and gave her a sad smile.

"How do you do this?"

"Do what?"

"Leave your son? I overheard you talking about your son and I just.."

"I do have a son, his name is Henry. Truth is, it's hard leaving them and it gets harder the older they get. But you just do it because you know whats on the other side. You know the worst thing world has to offer. "

"Thanks. I just.. this is the farthest and longest I've ever been away from her and I hate being so far. "

"I know but we're catching one bad guy at a time." Emily smiled at JJ and headed for the bathroom.

Later that night, JJ and Emily awoke at the sound of their phones ringing. Emily rolled over and looked at her phone, another body has been found. Both Emily and JJ both jumped out of bed and got dressed. When the team gathered, Morgan had made a big pot of coffee.

"I'm sorry to have woken everyone up but they just found another victim. 29 year old, Monica Anderson was found by a family that was camping a few hours ago. "

"Why didn't they call us when the body was found?"

They wanted to make sure that this was the work of our unsub."

"And is it?" Rossi asked

"Yes. They found the star on her chest. "

"Guys, The causes of death got me thinking. What if the unsub has a split personality?" Reid asked

"how do you suppose."

"it makes sense. All the victims were killed in all different ways but the only thing that ties them together is the star. What If he's killing people as different people?

"JJ can you get Garcia on the phone."

JJ shook her head yes and dialed a number.

"Hello sugar."

"Hello Garcia. We need you to look something up for us."

"Anything."

"I need you to look up Mason Skylar."

"I did that Earlier sir."

"I know but I need you to cross check him or his mother with split personality disorder. "

"Checking... Uhh A few years ago, his mother was diagnosed with split personality disorder"

"What happened to his mother? " Emily asked

"Uhh she died, a few weeks ago."

"That must of been the trigger." Rossi stated.

"What does his mother look like?" JJ asked

"Sending the picture now."

When the picture came up, Everyone looked at each other.

"This makes sense why he's targeting women with blonde hair and blue eyes. His mother has a resemblance."

"Why is he killing these women though? What did his mother do that was so bad to him." Emily asked

"We're going to have to figure that out. Garcia, please find out everything about him. There must be something in his past that will tell us something."

"Yes sir." She hung up the phone and continued typing on her computer.

A few hours later and few pots of coffee later, the team was hitting a wall. They had no new leads and no locations as to where there suspect is. Looking for him was hard, he had no job, no license, and no updated address.

The phone ringing, started the team. JJ sat up in her chair and answered the phone.

"Garcia."

"Hey, I have some news. So looking into Mason Skylar's past, he seems like an overall good kid. He had straight A's and was by definition a goodie two shoes kind of kid but by the time he was 15, he had been admitted by his mother."

"For split personality disorder?" Emily said

"Yeah, from what I can tell, his mother admitted him when he was 15 after symptoms started appearing. "

"Anything else Mama?" Derek asked

"After he was released, he kind of goes off the grid. I really don't have anything for him after."

"What if he is now living under the name of one of his alter egos?" JJ asked

"I mean it's possible but what does his mother have anything to do with this?"

"I'll call you when I've got something else."

"Thanks Garcia."

"Right now all we know that, Mason Skylar is killing the children of the victims of Robert Flynn. Is it possible that the girlfriend knew about it?" Derek asked

"D I D can sometimes be brought on by Trauma."

"So what are we saying here. Could the girlfriend be part of the original murders and Mason knew about it?" Rossi asked

"Morgan, Reid, and Prentiss, I want you all to go down to the crime scene and examined the new body. Rossi, JJ, and I will prepare the profile."

Arriving at the crime scene, Morgan, Reid, and Prentiss examined the woman lying in front of them. Another blonde haired, blued eyed woman. Proven by Garcia, her mother was another victim of Robert Flynn.

"Does she have the same as the others?"

"Yeah. We're going to have to call the other families and warn them." Emily said.

"I think we need to give the profile." Morgan said

The two other agents nodded and followed back towards the car.

Arriving back at the station, the team gathered with the other officers and began to give the profile.

"We are looking for 25 year old Mason Skylar. He is a Caucasian man with brown hair. He is the suspect in the recent murders. "

"He is suspected to be armed and dangerous." Rossi stated

"How would we approach?" one of the officers asked

"Since he has DID, it could startle him. He may not even be going by Mason at this time. He may be going by one of his personalities. It is extremely important that we proceed with caution. Our team is currently getting in contact with the other victims of Robert Flynn."

"Sir.. Sorry to interrupt but there is one woman, I could not get a hold of. "

"Who is it Garcia?"

"Madison Montgomery. She is the only one left."

"Send us her address, we are on our way. "

"Done."

When they got to the SUV, they all sped to the address that was provided. The drive was quiet, the team all not knowingly had the same thought. They wanted to finally catch this guy, and make sure the Maddison would be okay. They hoped for the best but sometimes, they couldn't save everyone and they knew that. They just hoped that today wouldn't be that day.

When they finally arrived at the house, the team got into position and was waiting for the cue to go. After a few minutes, the team was given the single to go. The swat team had knocked out the door and they had run in after the swat team intervened. Everyone was yelling clear until Emily heard the very mumbled cries of a woman.

"Hey guys over here." Emily slowly opened the door and walked down into what seemed like a basement.

"Hey prentiss, I'm coming with you. Be careful. " Morgan said

Emily nodded and Derek walked in behind her.

With guns pointing, Emily heard a noise the closer she came down the stairs

"Mason. Is that you?"

No answer.

"Mason, I'm here to help. Im part of the FBI, my name is Emily. Im here to help you."

"You cant help him." A voice said, holding a gun to Maddison's head.

"I can, and I promise to help you. I know that your mother tried to help you but she didn't have the resources like I do."

"Mason's mother was a murderer and then had him committed. She did not try to help him."

"Can you tell me where Mason is?."

"He's not here and he won't be back for a while."

"How about you let her go and then I can get you some help, just like I promised."

"Do you think we are really going to believe you? We have no one and I'm protecting him like he should have been by his mother and that loser of a boyfriend she had"

"Look at her, she's scared. Imagine how scared Mason used to be when Robert was around. If you really want to protect Mason, you would let her go. I promise you, I will get the two of you help. "

"LiAR." Mason then lifted the gun from Maddison's head and pointed it at Emily. Before he could get then gun centered, a gun shot was already fired.

It went silent, no one was talking. Derek looked over at Emily and then back at the Unsub who was now on the floor with a gun shot wound to the shoulder. .

"hey guy's, were going to need a medic in here." Derek said speaking into his microphone attached to his vest.

"Let me have the gun okay? No one is going to hurt you. We're going to help you. "

"Prove it."

"What's your name?"

"James."

"James, I promise. You're going to go with these nice EMT's and then you'll get the help that you and Mason need,"

The paramedics came and placed James on the stretcher. As he was willed out, his eyes never left Emily's. Creepy in a way, he knew that she promised and Emily was not about to break that promise.

By this time, the whole neighborhood had gotten word about and started coming out of their houses.

"Come on guys, it's 6 am. Go back inside." Rossi stated.

After a few hours, they were finally on their way back home and they couldn't be happier.

"Good Job Prentiss, talking one down on the first case is impressive." Rossi stated

"Sort of... he did try to kill me though. Although, thank you Derek for not letting him kill me."

"You're welcome."

She smiled at him and leaned into her chair. She couldn't wait to get home to her little girl.
