Though 1 Hogan Place was only a half hour walk from Quinn's apartment, Carisi insisted they take the subway a few short stops. "The faster we get there, the faster we get out and spend the day together," he said, swiping Quinn through the turnstile. The M Train picked them up and swept them downtown to the ADA's office. As they entered the building, Sonny's arm shifted and wrapped around her waist, pulling her up against him while they waited for the elevator. Quinn was enjoying how Sonny couldn't keep his hands off her, but gently pried herself away as a larger crowd started gathering around the elevator doors. She gave his hand a gentle squeeze as they walked in and she saw the corner of his mouth turn up as he hit the button for Barba's floor.

Sonny announced them to the secretary at the desk who held up a finger and dialed Barba's office phone. A door swung open and Sonny followed Quinn into the office, sitting down on one of the couches near Barba's desk. The ADA sat down on top of his desk, tapping a pen against his lips as he stared at the two of them. "So," he said, pointing at them with the pen. "Is this a thing now?" Quinn breathed in sharply and Carisi leaned on his knees, raising a hand.

"I hardly think that's the point of this meeting, Counselor."

"The point, smartass," Barba retorted, "Is that we just got a matching DNA hit on all our rape kits thanks to Miss Silver over here."

Carisi turned to look at Quinn who was staring at Barba with her brow furrowed. "What are you talking about? What did I do?" she asked.

"This might be hard to hear so I suggest you brace yourself." Rafael set down his pen and shuffled through the folders laying on his desk. "When we sent the DNA sample you gave to check if Mr. Daniels had any priors to make the case solid for a restraining order, Warner called and said it matched with all the rape kits we had for the serial case we were working on. Including Melanie Jackson."

"Quinn, you alright?" Sonny asked as her jaw dropped and the color drained from her face.

"I'm going to throw up," she said, pushing herself up off the couch and running towards the bathroom. The two men heard retching noises and Sonny leaned back on the couch, running his hand down his face.

"You're kidding, right?" Sonny asked.

"If I was kidding my face would not look like this, Carisi."

"Your face always looks like that, Counselor."

Barba shot Sonny a look and dropped the files on his desk. "Before we move forward with this case I need to know the extent of your relationship right now." Sonny shrugged and Barba sighed. "If you're emotionally entangled in this case you know I cannot let you into the courtroom."

"And what, reassign it back to Dodds? This back and forth is going to drive the lieutenant crazy."

"You're avoiding the question. I'm not asking purely from a professional standpoint, Carisi."

"Yeah? Then what standpoint are you asking from, Counselor?"

"I'm asking as a friend." Shaken, Sonny looked up at Barba, eyes wide. The ADA smirked at him, leaning back on his arms. "So, what's going on?"

Sonny paused before answering. Quinn was still in the bathroom - he heard the muffled sound of the toilet flushing and another loud retch. He got up and knocked on the door. "Ya need some help in there?"

"No. It's fine. Just a few minutes." Quinn's words came out labored and Sonny walked back to the couch.

"Barba," he mumbled, "How am I supposed to know the extent of our relationship after one night?"

"That's a fun question for a Bar exam," the ADA snorted. "Have you talked to her?"

"I didn't really have a chance to, Mr. I'm-Awake-At-Four-AM," Sonny shot back. "I was going to take her out and set things straight but you sorta ruined the mood for today," he said, motioning towards the bathroom.

Rafael sighed. "I'm sorry, but Olivia insisted we put this in motion. It's Tuesday and we have to catch this guy before he puts another girl in the hospital. He's been careful so far but after his mishap with Quinn I don't expect him to stay low."

Suddenly, the bathroom door swung open and Quinn emerged, looking disheveled and red-faced as she held onto the doorframe. "So," she began as Sonny leapt up to help her. "What's the plan?" The detective gingerly put his hand on her waist as they walked back to the couch. "You know, Fordham, I'm not dying." He ignored her and didn't let go until he had her sitting securely by his side while Barba watched with an amused smirk on his face. Quinn brushed her hair out of her face and looked up at the ADA expectantly.

"Well. This is the perfect situation. We arrest Daniels, ideally you and Melanie would testify, judge rules in our favor and case closed. If we have the three rape kits and Melanie's positive ID, this should be a fairly easy case to finish."

"You want me to testify?" Quinn exclaimed, digging her nails into her knees.

"I'm not going to force you, Quinn. We have a solid case without it, but it would help -"

"No, I want to. I want to ruin his life." She looked Barba dead in the eye and held his gaze as he studied her face. "I'm sure." Quinn answered his question before he could ask it and he nodded.

"Then we're done here. Quinn, I will be in touch with you as will Lieutenant Benson. Good work."

Sonny shot up off the couch, picking Quinn up with him. They quickly said goodbye to the ADA and Sonny swept Quinn out of the room, practically dragging her to the elevator. "Hey, my legs are shorter than yours, Fordham. Slow down." She panted as they waited for the elevator to reach their floor. "Are you okay?"

"I'm fine, CPEP. Just worried about you."

"Was it the barfing? I swear it was probably just sudden anxiety and the rest of last night's booze. I'm alright, I swear," she said, holding her hand over her heart. Sonny shook his head as the doors opened and he ushered her inside.

"It's not that," he said, pulling her close and nuzzling his nose into her hair. "I just want you to be alright. You've got a lot of stuff goin' on and not all of it is good stuff and I know I'd be overwhelmed if I were you." Quinn smiled and turned her head to give Sonny a chaste kiss on the corner of his mouth before pulling herself out of his grip.

"It's not as overwhelming when you've got the right person to help you through it," she said, earning herself a bright grin from Carisi. They left the building after the elevator came to a stop and Quinn felt her stomach begin to rumble. "God, I'm starving."

"I dunno 'bout you, CPEP, but I could eat a whole pastrami sandwich right now."

"I've never had pastrami before."

Quinn swore she could see Sonny go through all five stages of grief after her response. He looked at her in disbelief. "You've never had pastrami before? How long did you say you lived in New York again?"

"Uh… subtracting my four year stint in Chicago… twenty three years?"

"Twenty three years without a pastrami sandwich? You're joking." Sonny shook his head. "We're gonna have to remedy that today, CPEP. Whattaya say?"

"I don't even know if I'm going to like it, Fordham. What if it's just a colossal waste of money?" She put her hands on her hips. "Are you gonna take away my New Yorker card?"

"You're gonna like it, I'm sure of it." He held out his hand. "Come on. You're gonna get the full New York pastrami experience." She sighed, grabbing hold of his hand as he started walking uptown. Carisi was way too excited to feed her this sandwich and Quinn was slightly worried that she would disappoint him. He talked the whole way about his mother's cooking and favorite food, stopping occasionally to ask Quinn a question or two. "I know you're not really one to talk about your family but you had to have had a favorite food growing up, right?"

Quinn shrugged. "My mom used to make a mean shepherd's pie. And corned beef sandwiches like nobody's business. I guess that kinda sticks out for me."

"Then you're going to love this today. It's almost the same thing just cooked differently." Quinn looked up and saw that Carisi had stopped on the corner of Houston and Ludlow. "Here we are." The giant sign reading "KATZ'S" loomed over her as she gasped.

"You're kidding, Fordham. This place is so expensive. I don't think I brought enough money with me." Katz's Delicatessen was known for their high prices - something that deterred Quinn all her life.

"Good thing you ain't paying for it now, CPEP."

"No, I can't let you -"

"I don't wanna hear another word about it. You owe me a date, remember? I got you." Quinn felt her heart start beating a little too quickly and took a few breaths to steady herself. Sonny held the door open for her and they walked in, receiving two tickets from the men at the counter.

"Sonny, are you sure? I don't want to impose…"

"Quinn, you say one more thing that's not food and I'm ordering the most expensive thing on the menu for you." Carisi smirked at her and her eyes widened as she looked at the boards above the counter.

"I guess I'm here for a pastrami on rye, right?"

"One pastrami on rye and a Reuben," Sonny said to the man behind the counter. "Gonna see what all the fuss is about with your corned beef," he said, winking at Quinn. She watched intently as the man carved off pieces of meat and put some on a plate in front of them. Carisi picked one up with his fingers and motioned for Quinn to do so as well. "Try it. It's delicious." She reached out and grabbed a piece, cautiously taking a bite. The meat was soft and warm and practically melted in her mouth.

Their sandwiches were done in record time and Sonny grabbed the tray, heading to a table in a back corner. He put the tray down, pulling out a chair for Quinn and waited for her to sit. She furrowed her brow as she sat down, watching as he walked all the way around the table to sit across from her. Not knowing where to start, Quinn slid her plate closer and picked up a half of the sandwich. "This better be good, Fordham." Sonny grinned at her.

"Just eat it, CPEP."

She sighed and took a bite. If the slice of meat she had before was any indication of how good the sandwich was, the whole thing was ten times better. A little overhyped, in Quinn's opinion, but delicious and worth it nonetheless. She put the sandwich down, pulling a napkin from the dispenser. "Your turn." They took turns back and forth, taking bites and arguing about the different tastes and impressions. Finally. Quinn finished her food and pushed the plate away, leaning back in the chair with her hands folded over her stomach. "That was good, Carisi. Thank you."

Stunned, the detective put down the last bite of his Reuben.

"What are you looking at me like that for, Fordham?"

"It was good while it lasted," he sighed, shaking his head and finishing the sandwich.

"What are you talking about? I'll buy you more food if you're still hungry."

"It's not that, Quinn. I haven't heard you use my name - any of them - since I met you. Caught me by surprise, is all."

Quinn raised an eyebrow and wiped her mouth with another napkin. "Figured if you're going to start calling me by my name, maybe I'll make an attempt with yours, Carisi." He smiled and sat back in the chair. "So, does this satisfy that date I've owed you since March?"

"I dunno, CPEP. I seem to remember you saying something about 'never dating another cop again'." He crossed his arms, staring at her with a devious look on his face. Quinn huffed and crossed her legs under the table, bumping into his obscenely long legs. She knew he was up to something.

"Well I guess I have to make an exception for you, don't I?"

"Yeah, but that would imply you'd do it more than once."

"So what if I would?"

"You would?"

"Yeah."

Sonny got up with a start, picking up the trash and returning it to the appropriate rack. Quinn got up to follow and pulled out her wallet, earning a disapproving look from Sonny. "What did I tell you before? I got it." He reached for his debit card and paid for their food, placing his hand on the small of her back and exiting the restaurant. "Just to be clear, I was asking if I could see you more often on a more than friends with benefits basis."

Quinn burst out laughing. "Always the charmer, Carisi."

"Hey, this is a serious question and concern!"

"Okay. And the answer is yes. Yes you can." As Quinn answered, Carisi stopped on the corner, pulling her around in front of him. He placed both hands on her cheeks, dipping down to kiss her. She stood up on her tiptoes, holding on to his forearms. "Don't think your girlfriend is going to be too happy when she finds out," Quinn chuckled as he pulled away.

"Eh, you could take her," he smirked, throwing his arm over her shoulders as he walked her back home.
