I apologize for the way overdue chapter. Personal shit has been happening recently and I have been dealing with it. Now, enough talk and let me leave you guys read the chapter.

Enjoy!

Nick glanced between the dark haired man and the teen, who had stood from the chair. The detective turned his attention back to the man and stood taller. He took a step closer to the man and said, "And you are?"

"Agent Dean Porter," the man gruffly said. "Where is Cragen? I need to talk to him."

"He is in his office," Nick nodded towards the captain's office.

"Thank you," Porter said and nodded to the detective. He glanced back at Kat. "It was nice seeing you again, Kathryn Benson."

"Sorry that I can't say the same," Kat continued to glare at him as he walked towards Cragen's office.

Porter snorted and walked inside the office, not bothering to knock. Once the door closed behind him, Nick turned to look at the teen. "You know that guy?"

"He's an FBI agent," Kat glowered at Cragen's closed office door. "He worked a case with mom when she had to go undercover in Oregon years ago. Then they worked on another case here with my mom and her old partner."

"What's with the glare?" Fin asked as he walked inside the squad room with Rollins following behind. He and Rollins missed what just happened just a few seconds ago. "Did something happen while we were gone?"

"This Dean Porter guy is talking to the captain," Nick explained as he sat on his chair. "He didn't tell me for what exactly and just walked inside Cragen's office."

Fin turned to look at Kat again. "Tell me he is joking."

"I wished," she grumbled and sitting back down on the chair. She grabbed her notes again and tried to take her mind off the situation that was happening in the precinct. She could hear Fin saying something of Porter under his breath.

"Who is this FBI guy?" Rollins asked, still confused what the fuss was about.

Fin decided to tell his partner when he noticed Kat gritting her teeth. "He worked with us on a case three years ago. But before that, he worked with Olivia when she was undercover in Oregon."

"Your mom was undercover?" The blonde detective asked Kat, curious that Olivia had to leave New York for a case.

"She was working with another agent before it got assign to Porter," Kat peered up from her notes.

"But why don't you like him?" Amaro asked the teenager.

"Who don't you like?" Olivia asked as she walked towards them, with Munch walking next to her with a file. She stood next to her daughter and placed her hand on the teen's shoulder. When no one answered her, she furrowed her eyebrows. "Did I miss something?"

"Not something…someone," Fin nodded his head to Cragen's office.

"Who?" Munch asked.

Before anyone can answer, Cragen walked out with Porter. Munch and Olivia stared at the agent in shock while Fin and Kat grimaced. Kat looked away and pretended to be reading her notes. She didn't want to see Porter's face anymore. She had to suppress the temptation of throwing the notebook at his direction. Fin sat down on his chair, placing his feet on his desk and leaning back against his chair. Olivia and Munch continued to stare at Porter in shock, not saying anything.

"Detective Amaro and Detective Rollins," Cragen turned to look at his two detectives. "This is FBI agent Dean Porter." He glanced at his other detectives. "I'm sure you three remember the agent."

"How can we forget," Fin rolled his eyes.

"What does the FBI have to do with this case? This belongs to Special Victims," Amaro crossed his arms across his chest. He didn't want to give this case away to another department.

"Not now," Porter boredly said as he quickly glanced at the teenager in the room.

Cragen cleared his throat and gave Olivia a knowing look.

The brunette understood what the captain was telling her. She nodded at him and gave Kat's shoulder a gently squeeze. "Honey, why don't you wait for me in the cribs? I'll be there shortly so we can go home."

Kat huffed and closed her notebook. "Fine," she collected her stuff and stood from her chair. She glanced at Munch and saw him giving her a discrete wink. She knew that Munch will give her a few details when she would come out of the cribs. She smiled at him and walked away from the detectives.

"You have been quiet all day," Mark said, looking down at Kat.

"Sorry," she smiled apologetically at him as they continued to walk.

After school, they had decided to walk around High Line to kill some time. Mark didn't feel like going home and Kat couldn't be in the precinct because of the case. Not that she minded. She would rather hang out with her friends than see Porter in the precinct.

Mark stared at her in concern. "Did something bad happen?"

"Porter came to the precinct yesterday," Kat sat on a nearby bench.

Mark sat down next to her, remembering the agent's name from years ago. He remembered the anger that Kat felt towards the man for breaking her mother's heart. "The FBI guy? What he's doing back?"

"According to Munch, Porter," she hissed his name, "is working on a recent case with my mom and the others. I haven't been able to grill much information from him or mom. Mom didn't want to talk about it this morning."

"Sounds like a very big case."

"It is," Kat mumbled as she stared at one of the buildings. "I just want this case to be over so he could leave and stay away from my mom."

He could see the slight anger rising in Kat's eyes, so he decided to make her relax. He took out a sharpie pen from his backpack and grabbed her wrist. He ignored her curious expression on her face as placed her forearm on top of his knees.

"Don't think about Porter much," Mark nonchalantly told her as he began to draw a feather on her forearm. "Like you said, he is only here for the case. He will be gone soon."

"You're right," Kat sighed heavily.

"Why exactly don't you like the guy?" Mark asked, not taking his eyes from the design he was drawing on Kat's forearm. "You never really clarified it."

"There was a thing between my mom and him," Kat explained while she watched Mark draw on her. "The last time they worked together, he broke my mom's heart over the case. My mom was really heartbroken…just like she was when Elliot just walked out and never said goodbye."

Mark winced as he continued to draw. "It must have been difficult for her."

"It was," she grimaced. "I just don't trust him."

"But what if has changed these past years."

"Doubt it."

Mark snorted and sat up. He smiled at his finished design and glanced at Kat. "What do you think?"

Kat grinned as she saw the finished feather. She was awestruck on how realistic it looked. "Wow, Mark. I love it!" She smiled at him again and hugged him.

Mark blushed and hugged her back. "Glad you liked it."

"Definitely need to take a picture of this," Kat let go of Mark, much to both of their liking, and took out her phone. She took a quick pick and posted it on her Facebook, tagging Mark on the picture. "You're an amazing artist."

"Thanks," Mark smiled softly at her. "Want to continue our walk?"

Kat nodded and they both stood from the bench. They continued to walk around High Line without the mention of Porter or the case again.

"How long as Cassidy been working for you?" Olivia asked Porter.

The FBI agent had told Benson and Amaro to meet him at a café last night at the precinct. Cassidy would be under Ganzel's watchful eye for some time before he would be able to get in contact with Porter. The agent didn't want to blow his cover and decided it would be best of Cassidy wasn't present while he talked to the two detectives.

"From the beginning," Porter said, taking a sip from his coffee. "One of our suspects from a past investigation was murdered by one of Ganzel's men."

"And what does that have to do with Cassidy?" Amaro asked.

"Delia Wilson, Ganzel's competition, sent some of her goons to spook him out of business. It didn't work against Ganzel but he wanted to be careful. So he was trying to find a personal security in the NYPD. He wanted to find someone who was crooked or wouldn't mind getting their hands dirty."

"Cassidy will never go dirty," Olivia frowned at the agent.

"No, but he was desperate to do something that wasn't 'boring'," Porter rolled his eyes. "So I told him about Ganzel and he was very interested. And now he has been working undercover for the FBI for three years, which your unit almost screwed last night."

"The girl that was murdered was only sixteen," Amaro glared at the man. "It makes it our case."

"Look, I already told all of you last night. I'm willing to work together with your unit if it means bringing Ganzel down."

"What about this Delia? Aren't you interested in her as well?" Liv clutched her coffee cup closer to her. "Don't you want to bring her down as well?"

"My interest right now is Ganzel," Porter glanced at her. "You can her if you want. The girl was planted by her."

"And where can we find this Delia?" Amaro tapped his fingers on the wooden table. He wanted this conversation to be over as soon as possible.

Porter raised an eyebrow at him. "At Wilson Farm in Cambridge. I will text you the address."

Amaro nodded and stood from his seat. "I guess we will be in contact." He glanced at Olivia before grabbing his cup of coffee and leaving the café.

"He seems in a mood," Porter commented on Nick's behavior. "Then again, I will be the same way if someone wanted to take my case away."

"Give him a break," Olivia said before she too stood from her seat. "It was nice seeing you again, Dean."

Porter smiled softly at the detective. "The same here, Liv. We will be in contact soon."

Kat and Mark walked toward the nearest subway station after their walk around High Line. She didn't want it to end but she had homework to finish before her mother got home. The same thing went with Mark. They were close to the station when Kat saw someone she didn't expect to see.

"Eddie!" Kat grinned. She hasn't seen or heard from her friend since the rave and party.

His eyes widen in surprised before a smile appeared on his face. He ran towards his friend and pulled her into a hug that lifted Kat off her feet. They both ignore some of the disgruntle looks they were getting from people walking in the sidewalk.

"Where the hell have you been?!" Eddie asked once he put her back on her feet. "We tried calling and texting you but you never responded back."

"My mom grounded me and took and she took everything electronic away," Kat explained. "I don't know when I am getting them back. But from the looks of it, I won't be getting my phone back any sooner."

Eddie ran his fingers over his light brown, almost blonde hair. "We have been worried about you. Madison was going to pay you a visit this weekend to see if you were okay."

Kat let out chuckle and Eddie smiled at her. She turned back to Mark, who stood next to her. "Eddie this is my friend Mark. Mark this is Eddie," she introduce them to each other.

"Hey," Eddie waved at him.

"Hi," Mark said, trying to sound polite.

"Tell Madison that I'm fine and nothing bad happened," she said to Eddie.

He let out a relief sigh. "I was worried that something did happen to you."

They didn't notice the suspicious look Mark giving Eddie. Mark didn't know what to think of this Eddie guy that was standing too close to Kat or how did she knew him.

"I'll try to see you guys after I'm grounded. My mom is keeping a close eye on me," Kat sighed. "I have questions for both of that I need answering. Only you two could provide them for me."

Eddie nodded. "Of course," he glanced down at this watch and smiled apologetically to his friend. "I have to go. My shift is going to start soon and I can't afford another warning from my boss."

"Hopefully to see you guys soon," Kat said as she gave Eddie another hug.

He returned it heart fully and smiled at her. Eddie glanced at Mark and gave him a nod before walking away from them.

"How do you know that guy?" Mark asked, not taking his eyes from the retreating form of this Eddie guy.

She glanced up at him and noticed the frown on his face. "He's a friend that I met from another friend, Madison. I see them from time to time."

"He looks older," he grumbled.

"He is," Kat shrugged.

Mark fidgeted with the end of shit shirt and glanced down to the floor. "It looks like he is interested in you."

"Doubt it. But if he does then he is going to be disappointed," she smiled lightly. "I prefer someone my own age."

She wrapped her arm around his and pulled her with him to continue their walk. They were close to the subway station and she didn't want them to miss their train. She didn't notice Mark blushing or the small smile on his face as they walked.
