A/N: Hope you have a good new years eve my friends! I simply adore this song! But I did not mean for the story to turn out this way ... honest to God

The story starts when it was hot and it was summer and...
I had it all, I had him right there where I wanted him
She came along, got him alone and let's hear the applause
She took him faster than you could say "sabotage"

Things had been going great between them recently. When they first met there had been some friction between them because of her family ties and where her loyalties had originally laid. Before had had found out who she was he had not hidden his attraction to her, although at that point it was purely sexual. Admittedly the attraction had been mutual, he was very handsome and sexy, still was. In the recent months she had felt her feelings gradually shift from physical attraction to one on a more emotional level. To say Ziva David was falling in love was preposterous, she had always been a lone wolf, but she was certainly becoming attached. Her past lifestyle had made it impossibly for her to form emotional connections with anyone, there was always the risk of blackmail, death and pain. Growing up like this meant that this feeling was un-felt before, to be frank it was scary.

And then she had come along. Caused a distraction. Now he was no longer interested in her in any way, Ziva was simply there now. It had all happened so fast, one day Tony had been staring at her from across the bullpen then the next he was besotted with this other woman.

I never saw it coming, wouldn't have suspected it
I underestimated just who I was dealing with
She had to know the pain was beating on me like a drum
She underestimated just who she was stealing from

Ziva'd had the chance to stop it before it even happened, but she had seen no threat in it. How wrong she had been. They had even met a couple of times before, never acknowledging who the other was, never knowing that they would be later locked in battle.

The worst part of it was that the woman had known. Somehow this outsider had glimpsed behind Ziva's veil and seen her weakness – she had grown attached to something, to Tony DiNozzo. When Ziva had found out about their secret romance she had nearly fallen to the floor in pain. Her knees almost buckled, her legs almost gave up and her ability to breathe left her. She kept repeating her moto to herself, her mind screaming it through the crippling agony 'It only hurts if you let it'.

The woman was not the only one to be underestimated, when it was required Ziva could be ruthless. You had to be when working for Mossad. You had to not care. Be merciless.

She's not a saint
And she's not what you think
She's an actress

This woman did not care about Tony, she was just after a power trip. The feeling of ruining someone, burning them to the ground then taking their ashes and locking them inside an impossible box. So named because once it is closed it cannot be opened again

Soon she's gonna find
Stealing other people's toys
On the playground won't
Make you many friends

She should keep in mind
There is nothing I do better than revenge

Messing with a professional assassin was definitely not the smartest of things to attempt. They could easily kill you in a number of gruesome ways and in just as many inconspicuous ones. If you do ever mess with an assassin then you need to constantly watch your back, and your front and your head and your sides and just all of you. As well as your family.

I think her ever-present frown is a little troubling
And she thinks I'm psycho 'cause I like to rhyme her name with things

The way she looked at her was, quite honestly, frightening. No one else noticed it, they all loved her, thought she was brilliant. But the looks she cast Ziva's way were triumphant, they were showing her true character. More than once or twice she had publicly slammed Ziva, saying exceptionally hurtful things about her, accusing her of being things she most certainly wasn't. Sometimes the others even believed her and would regard Ziva differently. Slowly they were all turning against her, to them she was becoming the enemy. The hatred that was constantly passed her way was painful, it made her ache, it made her scream, feel numb, even she began to believe it too.

I'm just another thing for you
To roll your eyes at, honey
You might have him but I always get the last word

It was clear that she had no idea about the assets that Ziva had. She did not take her seriously. After the day that Ziva had dubbed 'that day' their interactions had been rigid, each knowing the others intentions and feelings towards the subject. She felt power, glee, joy, strength, she felt evil. Ziva felt powerless, heartbroken, pained, weakness, Ziva felt useless.

I never saw it coming, wouldn't have suspected it
I underestimated just who I was dealing with
She had to know the pain was beating on me like a drum

This was no longer a power trip, this was a murder attempt. Driving someone to insanity was one way to kill someone in cold blood while appearing innocent.

As Ziva sat curled on her bathroom floor, knife in hand she let the tears fall uncurbed down her cheeks. No one was there to save her. No one wanted to save her anymore. The pain was crushing, ever present, yet it was freeing, non-existent at the same time. She felt nothing but felt too much all at the same time.

Confused.

Knuckles white from the pressure she gripped the knife with a terrifying force, her fingers nearly shattering. Raising the offending object to her arm she traced the blue lines lazily.

"I'm so sorry" she sobbed as she drew carefully "I love you"

The knife bit into her veins, dragging itself down vertically. The most effective way to slit a wrist. One an assassin would know. Crimson rivulets spilled and splattered everywhere, the knife falling from her loose grip and clattering onto the floor like a hurried drum beat.

There is nothing I do better than revenge

If all she was good at was revenge then what was the point of her if she could not even manage that. The answer? None. There was no longer a point to her, she should no longer be. Emotions always get you hurt, it is best not to feel anything. Life lesson. No point. There was no point. They were all happy. She made them unhappy. She loved them. Happiness was important. They deserved to be happy. She had to die. There was no point in her existence anymore.

Beside her on the blood stained floor lay a piece of paper mirroring her last three words ... 'I love you'

A/N: I honestly have no idea where the darkness came from ... I guess I really am just a sadist.
