Of Murders and Proposals

Alexis Castle was not one to frequent concerts and if asked two months ago she would have vehemently denied even knowing who the hell Mandy Sutton was and yet here she was two months later waiting outside the back entrance of a concert stadium in Boston for her friend, the very same Mandy Sutton, to come out. She had admitted to Mandy in private that yes she did like her songs, she had all her albums on her iTunes, however she definitely disliked attending concerts with loud noises and stadiums full of sweaty, semi-inebriated people all jam-packed so tightly that it was almost impossible to not rub against each other. Forever a quiet soul, she had always preferred to stay at home whenever her friends decided to attend one concert or another that always seemed to be in town, so it was a wonder that she had agreed so readily to travel all the way to Boston to meet her friend at a concert, she had even offered free tickets for front row seats to entice her into coming.

She clutched those four tickets in her hand right now having the full intention of returning them to Mandy; she didn't need to be enticed into meeting her friend anyway, who had recently split up with her boyfriend again, this time amicably, but Mandy was still prone to bouts of depression stemming from the fact that her own mother had committed murder to keep her life a luxury. Alexis was usually on alcohol watch duty whenever Mandy did one of her concerts so she really didn't need much persuading to drive over. Besides with her recent breakup with her year long boyfriend Pi, she had changed her major to Forensic Pathology and wanted to visit the Boston Police Department if she had the chance. She had recommendation letters from both Lanie and her soon to be step-mother Kate, which would allow her to observe a case and the forensic science that went along with it. But that was not what she was excited for, she had studied everything that was needed about forensic science when interning with Lanie, what excited her was that the Boston Police Department was home to one of the most accomplished pathologists out there; Dr Maura Isles.

Alexis had been in contact with Dr Isles via email for the last two weeks discussing her visit and repeatedly thanking her for the opportunity to watch her work. Dr Isles was so accomplished that not only was she in charge of the entire Boston Pathology Department but also the whole Commonwealth of Massachusetts, she was the most consulted ME in the United States, even Lanie had freely admitted to periodically consulting with the renown Doctor. She had explained to Alexis that there were people who were good at what they do and people who were best at what they do, and it didn't get anymore best then Dr Maura Isles.

Suffice it to say that Alexis was fan-girling more over her than most adolescent boys inside were over her new friend. She looked around noticing it was getting dark, she wished her friend would hurry up it was getting late and she wanted to check into her hotel room, she also needed to call up Dr Isles and setup and appointment.

Just as she was getting ready to call up her friend she saw a car pull up at the far end of the stadium. For some reason the hairs on the back of her neck stood up, she quickly silenced her phone and turned off the screen, her instincts were telling her to stay low and be quiet, for some reason she felt like she was in extreme danger, she only hoped that Mandy didn't choose that moment to walk out, the men getting out of the car didn't seem to have noticed her but if the back door opened they would surely see them both so she bit her lip and prayed for the best all the while sliding down the wall to crouch low to the ground.

The men seemed be speaking English but they were too far away to hear. The were two distinct voices that she could count, she saw the short stockier one open the trunk of the car and drag out what looked like a bound and gagged person out of it, she didn't have to be a genius to know what was going to happen next but there was nothing she could do. She wanted to desperately call the police but knew that if she turned on her phone the light from the screen would be spotted immediately.

Alexis watched helplessly as a the taller man stood behind their prisoner and trained a gun on him. They knew as well as she did that no sound could be heard amidst all the noise, it would be the perfect cover. She saw the tall man's mouth moving, he was talking to the prisoner. All he could do was vehemently shake his head at whatever they had asked and all Alexis could do was watch as her tears rolled silently down her cheeks as one of the most ruthless crimes a man can do was committed right in front of her. She realized as split second before that when they pulled that trigger there was no way she wouldn't scream and from what she knew of her voice she knew they would hear it so she made a fist with her hand and shoved it forcefully in her mouth just as the man pulled the trigger.

Alexis' eyes widened as she watched the prisoners head snap back from the force of the bullet entering the base of his scull. She forcefully bit down on her hand drawing blood as the man fell face forward into the dirt, they both shot him three more times making sure he was dead. They searched the area for anyone who had seemed to witness their crimes, once they were certain of their safety they both got in the car a drove off.

Less then five minutes later Mandy found her friend crouched down against the stadium wall shaking like a leaf tears spilling, immediately growing concerned. She crouched down I'm front of Alexis and put her hand on the redheads shoulder.

The contact shook Alexis out of her daze, she immediately stood up almost causing Mandy to topple backwards. She frantically yelled at her friend. "Mandy quickly call 911, I just saw someone commit murder." she said and took off towards the far end of the stadium as she ran towards the fallen body with Mandy hot on her heels doing as she was told.

Jane waited for Maura to ask the inevitable question as they watched Casey push Patrick Doyle Seniors chair out to a group of people who recognized him. Maura 's full attention was on her friends as she asked, "Unless what?" feeling like her whole world was hanging on the answer to this very question.

Jane stared straight into Maura' s eyes, "Unless I marry him." she replied softly watching for her reaction. She was sure that her beautiful friend would do what she usually did and hide her emotions and support her decision but Jane knew that her eyes would betray her like they always did, they always spoke of so many things that the ME rarely said. So it was quite a huge surprise for her that her prediction was wrong; oh her eyes did express much, they filled up with tears, but her face visibly dropped and without another word she turned on her heels and quickly walked away, presumably not wanting Jane to see her that way.

Jane called after her once and when she didn't turn back she looked down at her phone but then shook her head, she would track down her best friend later, right now she had something else to take care off, Maura's reaction was all that she had needed to give her answer to Casey.

She walked over to the man in question her strides confident and sure, for too long had she become a puddle of goo over him. She had carried those feelings from a twenty year old crush and transferred it over to her current self when she wasn't even a semblance of her younger self anymore. She had been through so much, from Hoyt to Doyle, from Dominic to Bianchi. She could never even begin to explain to him about everything she saw and everything that she still carried with her and she didn't even want to.

She had been willing to ignore that niggling feeling in the back of her mind but Casey's rushed proposal had pushed it right to the front of it; ever since he had come back into her life he had been stringing her along, keeping her hooked on him while he went to fight a war knowing that she would be waiting for him, because she would have been, she had been waiting on him for the past eight months hadn't she? She had felt needlessly guilty when she wasn't there for his recovery from his surgery and so relieved and happy to have him back that she had immediately fallen in bed with him. Thinking that maybe sex would make up for not being there, for sleeping with Gabriel? She didn't even know, but now she realized that in her infatuation with Casey she had lost herself, she had become someone she had promised that she would never become; she reminded herself of one of those simpering bimbos that used to follow Casey around back in high school.

She had failed to realize exactly what kind of relationship Casey was roping her into, with the guilt trips and the constant cancellations in dates and Skype time, he had been rooting inside her a deep sense of insecurity that made her feel as if she wasn't good enough for him. It was done so that when he did come back she would fall happily into his arms and be with him, which she had done. But what Casey probably thought was the final nail in her independence's coffin was actually a huge wake up call.

She was not far gone as to not see an ultimatum when it was presented to her. Either marry him or he leaves for Afghanistan, forget ultimatum it almost seemed like emotional blackmail to her. When she really thought about what it would mean to accept a marriage proposal from Casey meant, she had almost kicked him out of her apartment. Very early on Jane knew that Casey didn't like her being a cop, she had put up with it due to her infatuation and due to the fact that he had not confronted her about it but she knew, and she also knew that one day he would ask her to quit, his reasoning would be that if he could give up the Military for her why couldn't she give up the Force for him. But the main thing that got to her was Maura. Her Maura. Accepting any proposal would inevitably mean losing the closest connection she ever had to a person. It was no mystery to her that her relationship with the honey-blonde Medical Examiner was the most important thing in her life, even if she wasn't head over heels for her and the very idea of not getting to spend enough time with her, not getting to see her every morning, noon and evening made her want to hurl.

Thinking about her feelings for Maura got her thinking about why she was dating Casey in the first place; when she had shot herself outside the precinct, all she could think about was saving Frankie and Maura, but when she felt her life leave her body as the EMTs all she could feel was regret; regret for not getting to see her beautiful face again, for not getting to smell her hair or hear her speak endless Google speak and she knew that she was in love with her best friend and would never get the chance to tell her. Grateful to be alive, she had resolved that she would admit it to her at the Award Ceremony but then she had shown up to the event on the arms of Dr Sluckey and it was like Maura's blatant straightness slapping her in the face. She had smiled the good smile and faked happiness for them while all the while she was screaming inside but then who would show up but Casey, a consolation prize but a prize none the less. She allowed herself to see past his blatant flaws and convince herself to ignore her unrequited feelings for her best friend.

It had worked for a while until she started realizing that ignoring feelings didn't make them disappear. Her attraction towards Dr Isles increased with everyday that went by as did her certainty that the ME would never feel anything towards her other than a close friendship. If it wasn't for her revelations a few weeks back she wouldn't have been sure what her answer to Casey's proposal would have been today. Unlike the ME she had a perfect poker face when Maura flirted with Dominic, or talked about Ian or made googly eyes at BT, but that still didn't mean it didn't hurt. It had gotten so bad that she almost considered sleeping with Giovanni in order to distract herself, but then Maura had come back; there was Jane licking her wounds after an unsuccessful chat with Casey, thinking about how much clothes Maura and BT still had on, trying to eat her Kale in silence and her gorgeous, beautiful, wonderful friend slid in opposite her seat. Her offhand shrug at the absence of the Bomb Tech lifted Jane's spirits considerably. She had enjoyed a wonderful dinner, silently fantasizing it as a date, and went home alone but happy.

From that day on Jane noticed a marked difference in Maura's interactions with her, she smiled at her more, touched her more, stopped talking about men to her, found reasons to spend more time alone with her, almost every night was spent at either ones homes and while not all of them ended in sleepovers most of them did, if Jane wasn't too careful she would equate Maura's actions to her own the first time she realized how deep her feelings ran for the ME, but Jane was careful; she didn't dare hold out hope in case she was wrong, she would enjoy the closeness as long as Maura gave it before circumstances caused them to seize most of their interactions. Casey's arrival dimmed Maura's mood considerably, she clearly hated not being able to talk to her as much, no sleepovers, no early morning coffee, or runs. Jane could clearly see the disappointment in her eyes and Maura's anguish caused her pain, so when Casey dropped his M-Bomb on her she decided it was now or never. She was never going to say yes to him anyway but as long it was there she could use use his proposal to push Maura into confronting her feelings.

So when Maura reacted to Casey's proposal the way Jane had hoped she would she decided the gloves had to come off. Her decision was made, she was tired of sitting on the sidelines with the consolation prize when she knew that she could give the ME the world. She was taking back control of her life and she would be damned if she let Casey or even Maura herself stop her.

She strode over to him, bringing her Detective persona to the fore feeling most confident in the skin she was most used to, she met him half way and handed him her house key. Casey looked at the key and back at her confused. "My answer is no, Casey." He went to speak but Jane stopped her. "Please be gone by the evening, leave the key under the welcome mat." She spoke with such authority that all Casey could do was nod stupidly, she tipped her head slightly and turned on her heel turning her back on him, she needed to find Maura.
