Spencer Reid and David Rossi arrived at Kia Marshall's foster parents house. They thought this was a good place to start, if they knew more about Kia's background it could help them in their investigation. They knocked on the door and waited, then a woman that looked around 60 years old answered the door.

"Can I help you?" She said, her voice sounded defeated.

"Hi, I'm David Rossi, i'm from the FBI. This is Doctor Spencer Reid. I'm wondering if we can ask you a few questions about Kia Marshall?"

"Sure, come in." She opened the door wider and the 2 agents went in.

"I'm Michelle." She said, looking distraught. She led them into an open plan living room decorated in blues and greens. Michelle sat down but the agents stood waiting to be asked.

"Take a seat."

"Michelle, can you explain to us what happened with Kia?" Rossi asked, sitting down. Reid did the same.

"I've fostered Kia quite a few times now. I feel awful, ever since I found out the police were getting the FBI in and that Kia could have been abducted, I've felt terrible. She's a lovely girl, always willing to help out. She's had a very traumatic past and that's made her very unwell. She suffers with PTSD so it makes her impulsive at times. When she didn't come home I just thought she had run away again. I just thought the police would bring her back."

"Can you explain about her traumatic past?"

"I don't know much, you'll have to speak to Ms Dobbs, her social worker."

"When was the last time you saw Kia?" asked Reid.

"She'd gone out. She'd spend a lot of time at the library, she likes to read. She just didn't come home. That was 3 months ago."

"Thank you Michelle. That's really helpful. Is Kia's room still the way she left it?"

"Yes. Feel free to take a look. It's the one right at the top of the stairs."

Reid and Rossi went up to Kia's room and started looking around. Reid bagged up her diaries, deciding he'd read through them and see if they could get some answers as to who Kia was. Rossi looked through the doors, in the wardrobe and found nothing personal. Not so much as a picture. She was obviously a very lonely girl, Rossi thought feeling saddened. But he knew if Emily and Garcia were with her, they'd look after her.

Noises above the pit, let the girls know that the man was back. Kia started to shake in terror, as Emily looked over at the terrified girl.

"Kia, what does it mean when he comes back. What happens?" Emily asked urgently.

"He either comes to take one girl away to torture or he kills them." Kia said, fear lacing her tone. She tried to keep up her strong girl act but Emily and Garcia knew it was fake.

The trap door opened and the man threw a ladder down.

"Don't even fucking think about escaping." He shouted down. "Kia, get up here."

Kia didn't move, she stood rooted to the spot. She knew she needed to move or it would be worse. Alot worse.

"No. Take me instead." Emily shouted.

"Fuck you. It's Kia's turn. Get the fuck up here girl."

Kia looked over at Emily with tears in her eyes and started towards the ladder.

"No way, take me." Kia reached the bottom of the ladder and started climbing.

"Kia." Emily didn't know what to say, Garcia started sobbing. When Kia reached the top, she turned to look at the other girls.

"I'll be okay." She mouthed. The man grabbed Kia's arm and roughly pulled her up. He slammed the trap door shut and Emily and Garcia could hear Kia's cries as she was pulled away. Both girls let out their tears and Emily, in a fit of rage punched the wall.

"Ms Dobbs? Can we please have a word?" Rossi said. Him and Reid had arrived at the social services office to try and find more information about Kia Marshall. "I'm Agent Rossi and this is Doctor Reid."

"Sure, come through to my office." They all went into Ms Dobbs office and she motioned for them to take a seat.

"I presume you're here about Kia." She said, with a sad look on her face.

"Yes. Can you tell us more about Kia's background?" Reid asked.

"Kia's parents are drug addicts. She's been in and out the foster system since she was 5 years old but we completely removed her 2 years ago. Her parents didn't care about her. They used her to get drugs, they let drug dealers have sex with her so they could get their next fix. The poor thing is traumatised, i'm so saddened that this is happening to her."

"How was she as a person?"

"She was lovely and she's always trying to please people but she's sick. She has complex PTSD and self harms as a way to deal with the pain of her past. She also has anorexia."

"Can you think of anyone who would want to hurt her?"

"Of course not. But I guess her parents drug dealers might want her if they owe."

"Thank you."

Reid and Rossi exited the room and decided to travel back to headquarters to see if the others had any more information on who the unsub was. They knew they were running out of time.
