A/N: I should probably warn you that the drama in this chapter is more like tragedy, and somebody will die.

Chapter 5

Maura was inside the burned down warehouse, appearing to be examining the building's blueprints, when in fact she was waiting for the killer to show up.

Jane and Frost were standing hidden around the corner, with their guns drawn, intently listening for any sound that could indicate their suspect was there. Korsak and Frankie were in a car outside, ready to jump into action when needed.

All of a sudden, Jane spotted a figure out of the corner of her eye. "What are you doing here?", she silently mouthed, her eyes pointing daggers at the unexpected intruder.

Agent Dean locked eyes with the brunette detective and just shook his head, indicating there was no time for him to explain his presence.

Jane looked over at Frost, asking him without words if he knew why the FBI had just joined their undercover operation. But the younger detective just shrugged his shoulders, indicating he had no idea either.

Regrettably Jane was all too familiar with this particular FBI agent. A few years ago the two had gone on one date, well, half a date really, since Jane had quickly found out she couldn't stand the man and she'd left him before dinner was finished.

Unfortunately their paths still crossed occasionally, and here he was again at their undercover operation.

There were only ever two reasons for him to show up in Boston. It was either because of Hoyt and one of his apprentices, or Doyle. Since the first option was very unlikely, Dean's appearance had to do with the latter.

Which meant... 'oh no', Jane realized, 'Doyle was here'.

Jane was just about to clue her partner in when a man's voice was heard throughout the building, "You looking for where Greg died?"

All three of them immediately refocused on the situation at hand. Jane covertly glanced around the corner, while making sure she was completely out of sight.

"Yes," she could hear Maura say, the doctor's voice was calm.

"It's Kevin Flynn," Jane softly whispered to Frost.

"I had to make people understand that they just can't keep laying us off," Kevin defended himself, "and then Greg started digging around, just like you."

Jane's gut instinct went into overdrive, hearing the implied threat to Maura. All three of them moved to step in, when she heard the doctor's cry, "Kevin, don't!" Followed by a gun shot.

Then seemingly time moved faster and slowed down at the same time.

Paddy Doyle was standing high above them on a catwalk. His gun still smoking from the shot he had just taken; he had brought down and killed Kevin Flynn.

Agent Dean jumped out, gun raised, "drop your weapon, Doyle," he said, aiming his gun at the mobster.

Jane followed quickly behind, "Dean, no!" she yelled out, but it was too late. The agent had already taken the shot, hitting Doyle square in the abdomen.

The mobster grabbed at the wound, then aimed his gun, took a shot, and hit Dean.

With that many shots being taken in such short succession, all Jane could do was act herself. She raised her gun, training it on Doyle, her finger flexing to pull the trigger, when she heard Maura scream at her.

"Jane, no!"

And for just a split second, the detective hesitated. She looked at her fiancee, instead of at the mobster, who was still pointing his gun at her.

So when the gun went off, it took Jane by surprise, and so did the shove against her body that momentarily knocked her off balance.

In the corner of her eye, she saw her partner Frost fall to the ground, and she quickly turned her head back to Doyle. She took aim, 'double tap', hitting the mobster twice, both times center mass.

Paddy Doyle staggered momentarily, then started tumbling backwards, crashing through the railing of the catwalk; falling, only stopping when he hit the ground below with a sickening thud.

Jane immediately stumbled over to the men lying on the ground behind her. Agent Dean was down, groaning and clutching at his leg. But he would be fine, and Jane directed her attention to detective Frost, who still hadn't moved. He was lying face down, blood starting to pool around his body.

"Frost, no." Jane grabbed his shoulders and turned him around, to inspect his injuries. A large bullet hole in the middle of his chest. Her fingers went to his neck, checking for a pulse, but she couldn't find one. Fear and panic were starting to overtake her, but her actions came from instinct. The detective put Frost down on his back, and started administering CPR; her hands on his chest, pumping in a life giving rhythm.

"Maura!" Jane shouted, while continuing her actions. Occasionally stopping the massaging of Frost's heart, to breath air into his lungs.

The detective looked over to where she had last seen the doctor, and she was met with something that angered her deep inside her bones. Maura was bent down over her biological father, a mobster, a killer, and she was crying. Clutching on to him, saying something that Jane couldn't hear.

The brunette kept up her efforts on Frost, focusing on her partner instead of what was happening on the other side of the warehouse.

Time felt as if it had sped up, even though in reality, only two, maybe three minutes had passed.

"Frankie, call a bus!" Korsak shouted at the younger Rizzoli, falling on his knees next to Jane. "What happened?" he asked, taking over the brunette's efforts to revive Frost.

Jane was unable to speak, she was just staring at her partner bleeding out on the ground. Several thoughts racing through her head, one after the other. 'Frost took a bullet, that was meant for me. I hesitated, and Frost got shot, because of me. Frost is dying, because of me.'

Frankie came running inside, "they're three minutes out," he said almost breathless. He glanced at his sister, who looked like she was going into shock. "You hurt? Where's Maura?" he asked, trying to catch her eyes.

Jane slowly shook her head, then lifted her hand and pointed to the other side of the building.

The younger Rizzoli looked to where Jane was pointing, "what the fuck is she doing over there? She should be here, helping Frost," Frankie shouted angrily.

It wasn't long until they were joined by several EMT's and paramedics, who quickly pushed them out of the way, so they could attend to the injured.

After his initial treatment Agent Dean had managed to hoist himself off the ground. He was now calling his own unit to join him at the scene.

When Jane saw the federal agent getting up, something inside of her snapped, and she lunged at the man. She would have hit him too, if it wasn't for Frankie holding her back; struggling to restrain his sister.

"Jane, stop! Go outside," Korsak said, trying to redirect the brunette's attention.

Jane refused to move, not wanting to leave Frost's side. The paramedics were working diligently to revive him, trying to get him to breath, to get a pulse. They used the defibrillator on his chest several times, each time increasing the power, but with no result.

Until finally, it was over.

With the damage that was done, the amount of blood he had lost, the time that had passed since it happened. There was nothing more they could do.

Frost had died almost instantly.

Even with all of their efforts, they couldn't bring him back. First Jane, then Korsak, and finally the paramedics had tried to revive him, but it had been in vain.

Detective Barry Frost was gone.

Around the same time the news sank in with everyone present, that they had lost one of their own, Jane could hear Maura's cries. The doctor obviously in shock herself, was trying to shield Doyle's lifeless body, from the paramedics who were trying to move him.

Even though she was almost drowning in sadness and anger, Jane couldn't withstand Maura's distress. She walked over to where the doctor was still on her knees next to the mobster on the ground. With a quick motion, she pulled Maura up and tried to turn her around to hold her.

Jane didn't know what she expected to happen, but it was definitely not what actually did happen.

"Don't touch me," Maura shouted pushing Jane away from her, "don't you dare touch me."

The brunette quickly withdrew her hands, as if she was burned.

Maura, completely submerged within her own emotions, completely unaware of anything else that had happened, of anyone else that got injured, just gave Jane a deadly glare.

"This is your fault, you killed him…you...executed him," she spat at the detective, then turned to go back to Doyle's body.

Jane was in complete shock at Maura's reaction. The look in the doctor's hazel eyes, was one of utter hate and disdain. Put that together with the few words she had spoken, it irrevocably damaged something deep inside of Jane; her heart.

The detective staggered backwards a few steps, then turned and all but ran out of the building. Where she was met with the sight of detective Frost's remains disappearing into a body bag, before being lifted into a waiting car.

Jane bent over at the middle, and emptied the contents of her stomach. She would have toppled over to the ground, if it wasn't for her brother's hand steadying her, leading her off to the side, away from prying eyes.

The detective slid down against the wall. Her legs pulled up against her chest, her arms wrapped tightly around them. Her eyes were closed, and she felt herself slide into a state of complete shock, where she would be unable to respond to anything or anyone. She was getting lost in her own mind, and she didn't care, so she let the darkness overtake her.

Frankie sat down next to his sister, and wrapped his arm around her shoulders, trying to keep her warm. Hoping his presence would be enough to help her come back out of it.

At the same time, Maura was leaving the building, still unaware of anything that happened beside the initial shots being fired.

When Kevin Flynn pulled out his gun, she had crouched on the ground, covering her head. She heard, rather than seen the gun, that killed Kevin. She had looked up and saw Paddy Doyle, standing high above her on the cat walk. And then it was as if all hell broke lose. She saw agent Dean step forward, aiming his gun at her father. She heard Jane shout something, then Dean shot her father. Another shot had come from above and Dean dropped to the ground. Then Jane aimed her gun at Doyle, and Maura yelled 'no'. Then everything became a blur, when several more shots were fired. And when she looked back up, her father came crashing to the ground. 'Why had Jane shot him?'

She had kneeled next to Doyle on the ground, and even though she had tried to help him, he had died shortly after. Jane had killed her father, and the emotions that swirled around inside her head were confusing.

Completely dazed she had sat there, next to him. Hearing sounds, voices, but not really registering what they were saying. And then the paramedics came, and wanted to move her father's body out of there. But they couldn't do that, he was supposed to tell her who her biological mother was. If they could bring him back, he could tell her. She had cried out at the paramedics, then soon after, she was pulled up by two familiar hands. She had turned around, furiously looking at the face of the person that took the answers away from her. And all the while she was thinking, 'why had Jane killed her father?

It was at that moment, when Maura was trying to replay everything that happened in her head. Still trying to make sense of it all. When she was grabbed by the arm, and not too kindly, by a very upset looking sergeant detective Korsak.

"What did you say to her?" he tore into Maura.

The doctor's mouth fell open, not quite understanding the man's brutality with her.

"I…I," Maura was actually a little frightened, she had never seen Korsak this angry, ever. The man usually was all friendly, caring, polite, and full of jokes.

He had no right to treat her like this, it was her father that had just gotten killed here.

"She killed my father," Maura defended herself.

"What is wrong with you?" Korsak finally let go of her arm, but stayed standing in front of her, blocking her escape.

"Wha…what do you mean, what's wrong with me?" the doctor was actually a little offended.

The older detective wasn't sure what he should say next, he briefly wondered if Maura even knew exactly what had happened, or if she had been so caught up by Doyle that everything else had gone over her head. He opted for the first choice, since he refused to believe that this woman, that was always so kind and warm to everyone, could be this cold hearted.

"You have no idea what happened, do you?" His face finally took on a more neutral expression.

Maura looked at him puzzled, of course she knew what happened, "agent Dean, crashed our undercover operation. He shot my fa-… Doyle; who then shot him. Then Jane shot and killed Doyle," she explained.

Korsak shook his head briefly, "Maura, Doyle shot Frost."

"What?" hazel eyes widened in shock, "that's not possible. Is he okay? Where is he?"

"He didn't make it, Maura. Frost is dead."

The doctor shook her head in horror, things all of sudden started to make sense. If she believed it was possible, she could have sworn her heart just dropped into her stomach. Her mind was going over the things she had just told her fiancee. "Jane, where's Jane?" she frantically asked the older detective.

Korsak looked around, he didn't know where the brunette had gone off to. His eyes scanning the crowd, he spotted the brunette detective's brother standing to the side.

At the same time Frankie saw them too. The young man's face was dark and angry, with quick strides he made it over to Maura.

"It should have been me," he shouted at the doctor.

"What?" Maura responded, confused.

"It should have been me," Frankie repeated, "that's what Jane was saying, over and over. It should have been me, it should have been me."

Maura clasped a hand in front of her mouth.

Korsak directed his attention to Frankie, "where is Jane now?"

"I don't know," Frankie fiercely shook his head, "She snapped out of it, said she was fine. She asked me to get her some water. I left her alone for less than a minute, and she was gone. We have to find her, Korsak."

The older detective looked at both Maura and Frankie, "we'll find her. We'll find her." He repeated, several times, as much for their benefit as well as his own.

A/N: Yes, sorry to all the Frost fans. I didn't want to kill him, really I didn't; I like the guy. It was just me playing the 'what if' game. 'What if' Jane had actually hesitated when Maura screamed, 'No'!, what would have happened? At the end of 3x1 when they were in the hospital, Maura asked Paddy if he would have shot Jane, he said, 'hell yes, she's a cop.' So I believe if Jane hadn't take that shot, either Jane or Frost would have gotten hit. I didn't want Jane to be the one to get shot, because it's been done. So Frost died a hero, saving his partner.

I'm sure you didn't need an explanation, but I felt like giving it to you. ;)

So any thoughts? *hides*
