Everyone was still in shock after finding Kelsey still alive and Riley dead. As the major crimes detectives along with JJ, Reid, Rossi and Morgan watch the ambulance take Kelsey away and the coroner is bagging the dead girl when Prentiss walks out of the house with some unsettling news.
"Guys we have another problem."
"What's wrong?" Reid asked. Prentiss looks uneasy.
"You need to see this."
Everyone followed Prentiss into the house and up to a room in the second level of the apartment that was covered with pictures of another little girl. They were shocked at the sheer amount of pictures of this girl in the room.
"Who is this girl?" JJ asked. Reid walked in and immediately recognized her from Foster Knowles' files.
"It's Austyn Knowles. She's Foster's sister." Reid said. Everyone looked at each other in panic. They realized they should have thought to find Foster's mom and sister and put them in protective custody.
"We need to get to them now!" Dalton said in a hurry. Everyone ran out to their cars and rushed over to Knowles' family's house except for Eric. Eric decided to head over and let Riley's dad know what they had just discovered. The agents of the BAU and the detectives of the Metro had lights and sirens on every car as they bolt over to the Knowles' house to give protection to the family. The teams passed by the Bayne apartment where Eric was headed. He took a deep breath and knocked on the door as the red and blue flashes went by him. They finally pulled into a cul-de-sac of apartment buildings where there was a woman frantically banging on everyones door and making chaos. She was screaming and started pulling hair of a random guy on the sidewalk and when Reid and Rossi got out of the suburban she ran up to them and attacked them.
"Whoa Whoa!" Reid yelled.
"Ma'am!" Rossi yelled as he tried to get her off. Morgan and Hotch heard the commotion and pulled the woman off of Reid.
"Who are you?" Morgan asked loudly.
"I want to know which one of these bastards took my child!"
"Are you Marla Knowles?" Morgan asked as she hit her fist against his chest.
"Who wants to know?" she asked crying.
"FBI." Morgan said holding his badge up.
"DC Metro." Danny said chiming in.
"What's the problem?" Morgan asked as he adjusted her to stand up properly.
"My daughter is gone." she drunkenly sobbed as she hit her fist against Morgan's rock solid chest. Everyone around her could smell the aroma of alcohol on her.
"Is your daughter Austyn?"
"How did you know that?"
"We have reason to believe that your son took her." JJ said. Marla looked up at her with dried tears on her face looking confused.
"I haven't seen him in seven years. Why would he do this?"
"We'll explain later, but we believe that Austyn is in a lot of danger."
"Do you know where Foster might go to clear his head?"
"How am I supposed to know?"
"Because you're his mother. Don't you know your own kid?" Cassie asked.
"You don't know me, you skank!" Marla yelled. Cassie raised her eyebrows at her. Meanwhile Hotch and Prentiss were on their way over to talk to Foster's last employer. Since his mom was not being very helpful at all, they figured his last employer would be the next best thing to figuring out where Foster had taken his sister. Hotch stopped the large dark van in front of a hardware store and he and Prentiss walked in there authoritatively. A man working at the customer service desk was too focused to notice them come into the store.
"Excuse me sir?" Hotch said in his deep and stern voice.
"What can I do for you?" the guy at the desk said taken aback by Prentiss. He looked at her with google eyes.
"Hey eyes up here buddy! We need your help."
"I can help you with anything you need." he said. Hotch slammed the picture of Foster Knowles on the table.
"Easy slammy." the guy said.
"Do you know this guy, yes or no?" Hotch demanded. He held the picture up closer.
"Oh yeah it's Foster."
"We need to know where he might go on his breaks."
"He was always disappearing during his shifts, I always ended up finding him in the parking lot across the street."
"Let's go." Hotch said.
"If you need anything else, call me." the guy said. Prentiss stared at him skeptically as they marched out. They called for the rest of the team to meet them at the parking garage. They got the SWAT team and vested up for a showdown with a monster. Behind the SWAT team, JJ and Hotch were the first ones to follow. Gun drawn, JJ was looking intense and hellbent on finding this killer. Hiding under a small Honda car was Foster with a loaded semi and a silencer. JJ suddenly felt a pain in her lower leg and then it started to go numb. As she tried to walk further, her leg started to go limp. She stumbles and grabs a hold of a truck in front of her.
"JJ, what's wrong?" Hotch asked.
"Uh…" JJ was confused and looked down to pinpoint the source of the pain.
"Someone call an ambulance!" Morgan yelled when he saw a trail of blood coming from JJ's leg. She fell onto the ground looking like she was going to pass out. Hotch and Morgan ran over to her and told Reid and Prentiss to keep going. The detectives ran behind the row of cars where they thought the shot came from. Behind a support beam in the garage was where Foster was hiding with a gun in one hand and his other covering his sister's mouth to keep her quiet. Austyn is breathing through her nose as she quivers and tries not to lose it. Her curly brown hair is pushed up against the beam. She has never seen her brother act like this before and it is seriously scaring her. Reid catches a glimpse of something behind a structure beam. He motions over to Prentiss and Cassie and they surround the beam by the stairs. Foster gets a glimpse of everyone surrounding them by looking over his shoulder. He knows there is limited options for him at this point.
"Foster Knowles, Metro Police!" Cassie yelled.
"FBI!" Prentiss yelled. Foster takes his hand off of Austyn's mouth and grabs her by the arm which makes her whimper in fear.
"Everyone of you better back off or I'll blow her head off!" Foster yelled. Austyn sobbed hard as he put the gun against her head.
"You don't want to do that Foster!"
"Why the hell not?" he yelled. Cassie slowly started to put her gun away.
"Listen to me! We already have you on kidnapping, attempted murder and murder. If you let her go, we can talk to the judge about taking off the death penalty, but you gotta let her go!"
Foster kept on backing up to the staircase and Cassie, Prentiss and Reid follow him. Everyone corners him when he gets onto the staircase that is backing up to the back alley.
"She was always the little princess and what was I to my mother? I was worthless. Everything I have done in my life means nothing!" Foster said angrily.
"That's not true Foster." Reid said as he kept his aim. "You did a great service to your country, doesn't that count for something?"
"The Marines was the best thing I could have found and they didn't want me either. I'm a nuisance in this world!"
"Foster, look at me!" Prentiss said as she put her hands to her side and put her gun away. "Let me come over there and get Austyn out, she doesn't need to be a part of this."
"She hasn't suffered in this life! I'm giving some to her."
Foster stared at them intently. They scream at him as he begins to raise his gun at them. Everyone is demanding he put the gun down, but they are faced with no choice but to shoot. Cassie had the best shot, so she fired twice. Foster hit his head against the concrete wall as the blood coming from his head splatters onto Austyn. Austyn freaked out and ran to Reid. Cassie lowered her head and walked back down to her team. Danny could saw her come down looking disheveled.
"What happened?" he asked. She looked to the side and back at him. She put her hand on her shoulder in an uncomfortable manner.
"I killed him."
He walked up to her.
"Cassie, you had no choice. He was a bad guy…"
"I know, I know that. I just wish that the girl didn't have to see it."
Danny rubbed her shoulder.
"She'll be okay."
Just as they were talking, Marla Knowles and Austyn were reunited. Foster was now in a body bag on his way to the morgue. Everyone breathed a sigh of relief. Everything was now in harmony. The members of the Major Case squad are now back in their house.
"I heard Chase is in ICU recovering. How is he?" Cassie asked Eric.
"He's doing great. He'll back next week!"
"Did Chase say that or did the Doctor?"
Eric paused for a minute.
"Well Chase knows himself better than the doctor."
Cassie smiles at him. "I heard the agent from the FBI pulled through too."
"That's great. She was a… great woman."
"I also heard she's married."
Eric sighed. "There's always a catch."
Danny hit him on the chest and smiled. Chief Northam walks in the squad room.
"Everyone go home. Good work today."
Everyone went home on the success of the day.
