A/N: Merry Christmas Corrosive Moon!

I might have messed up here a bit… as I gathered all of the reader's requests I put them under "light", "dark" or "undecided" according to your wishes… I found this wish under "light" though, and it didn't SOUND very light… well… it COULD be, but the plot-bunny that bit me was the serious kind… so this goes under dark. It's not DARK dark, (that is, nothing dark happens) it's just not very fluffy… ;)

Warnings: bit angsty… also AU in the canon-but-not-quite way.

Siren

I should have known there was something special about the boy… as just a child he stole the attention and adoration of hundreds of people every night, performing with his parents. And then, after they died, he somehow made Bruce Wayne, the reclusive and cold-acting millionaire, share not only his home but also his life's mission. The Dark Knight suddenly had a sidekick.

Robin grew but needed more than Batman could give him, although he would never quite know what it was he was missing. I know. Attention. Don't get me wrong, he's not an attention-seeking brat, but he needs someone to… focus on him… and it's not his fault. It's his nature. Bruce couldn't give him that, because his main focus will always be Gotham.

After leaving the great, dark city it didn't take long until he formed the Titans. Again an almost incredible feat: uniting a group of strangers, misfits even, most of them not even wanting to be part of a team… but he did it… and he became their leader. Quite extraordinary for a mere human boy. But he's not. Not human that is.

I could have dismissed the idea as people being saps or just sheep, looking for someone to lead them, but then I met him myself, eye to eye.

It wasn't so bad at first, not until he got interested in me… and then… First there was just fascination, then obsession. I couldn't think of anything else, nothing or no one seemed more important than my little bird. I did have moments of clarity, however, and it was at one of those times I figured it out… Robin is a Siren.

Don't get me wrong, he's not one of those half-naked bird-ladies that sit on cliffs singing to sailors. In fact, I've heard him sing once, and it's not that pretty. On the other hand, if he was naked on a cliff I would probably abandon ship to get to him…

No, Sirens look as human as you and me… well… as you, and no matter how much research I make, I can't find their origins. There are quite a few examples of what they can do and have done, both as heroes and villains, throughout history. They can make people follow them, almost mindlessly, and also have individuals do incredible things for their sake. Ever heard of Catherine the Great? Gustav Vasa? Well, maybe Joan of Arc, Helen of Troy, or Adolf Hitler seems more familiar?

Sirens do not have to be involved in wars or rule countries, however. They can be the girl next door, the cute boy in your math-class, and most of them don't even know they are Sirens, and neither do their surroundings. Their friends do tend to wonder how they got talked into things now and then, however, but mostly it's benign... Some Sirens do suspect that they have some kind of gift, however, and how they use it depends entirely on their personality. They might become sect leaders, motivational speakers or… well... Oprah or Dr. Phil. I'm sure there is a difference.

As far as I can tell, Robin has no idea. He thinks people follow him because he's trying to do the right thing, because he's a hero. Silly little bird.

People do not automatically fall under his thrall, however. If that was true, Jump would be crime free. He has to either feel passionately about something and/or really focus on the individual as far as I can tell. I'm not saying that he doesn't affect the criminals at all, quite the opposite. Robin wants adventure, and, now and then, he loves a good fight… his needs are met. I am rather sure that Jump city would, in fact, not have quite as many villains if Robin had not settled here… but that's a hypothesis, I'm afraid. All I know is that he has kept me here, when I was just supposed to be passing through.

I'm deeply under his influence by now, more than anyone else, because he got attracted to me. I was almost taken aback at first, he was just a kid then, not even seventeen. Now he's nineteen, and here I am. Still here… still at his… service.

He's curled up next to me right now, in my bed. He's resting and I've made sure he needs it… I do everything to please him, after all.

His nose is pressed into the crook of my neck, and one arm and one leg is thrown over my body as I lay on my back, staring up at the ceiling. He makes a little noise and curls up even closer. I sense that he's a bit cold and pulls the covers up with my free arm. He sighs happily and falls into a deeper slumber.

Fuck.

I did it again.

I've tried everything to resist… I've experimented by shutting off my senses; sight, smell, hearing, but he still gets through. I tried it with him too… he thought I was being kinky… he liked it and the sex that brought on… I haven't even thought of such things in years…

He cuddles me, like I'm some sort of teddy bear, someone safe, there just for him… and when he is around, I am. And I hate it. I'm a killer, a mercenary for hire by anyone with the right amount of cash. Since Robin got his eyes on me, however, I've barely been in a fight. I'm more of a detective now, helping the Titans, although unofficially. I killed once, though. A child molester. Robin hated him from the moment the first body was found, and when I told him that I had found him… Robin looked at me and said that he wished people like that man didn't exist. That night I felt a need to go back to that house and, surprisingly enough, nothing held me back. The Titans swooped in only a few hours later to find the body. Robin found me the next morning. He said he would forgive me. Just this once.

You see? I'm just his puppet, and he doesn't even realize it.

It has to end.

I'm not a good man, I'm not a hero. I can't let myself be controlled like this. I'm not a servant, not even to him. He has became the center of my life, my sole reason to exist, and that has emasculated me, made me feel helpless… made me fear for him… and fear him.

He can make me die for him, I know that. If a notion like that grabs him, some romantic crap about the ultimate sacrifice… Well, I'm not immortal, after all, my powers can only heal so much… And I don't want to die. Not for him, not for anyone. I want it to be my decision, or at least a damn work related accident…

There's only one way to stop it. I have to kill him. But I could never do it when he's this close, even thinking it now, makes me hold him a little tighter. He smiles in his sleep, thinking I'm hugging him close because I love him so much… poor boy… he's innocent in this too, I know that. But I can't live my life in a prison, I can't live a lie… I have to break free.

The only way to do it is from a distance. A sniper-gun. I want to do it myself, not hire anybody… I owe him that much. A clean shot. He won't even notice it. My head is clearer the further away I am from him, but I can't leave. I've tried. In these years I've left Jump for three days at the longest and I was a wreck when I got back, until I was back in his arms. And that was with him knowing I was leaving for a while… I had his approval…. I shudder at the thought… As if I, Deathstroke the Terminator, would need a teenager's approval for anything…

No… his death is the only thing that will set me free. I've known that for a long time now, but I keep putting it off… keep hoping he'll find someone else to focus on… keep hoping he'll let me go… I instinctively know that he won't, though. Robin is a devoted and faithful lover, just as he has made me… so he needs to die.

One thing is holding me back, however. Fear. I'm afraid I'll do something I've never done before…

I'm afraid I'll pull the trigger…

… and regret it.

The End

A/N: if you think that "bird-ladies" should be "fish-ladies" look "Siren" up on Wikipedia… the original ones, in the Greek mythology, are not mermaids, but women with wings… I just thought I'd mention that so I don't have to answer reviews about it… ;)

This was very interesting to write… sometimes, when I write fluffy Slade, I have this feeling that there's this little killer inside him, trying to get out, shouting in frustration… so I let him speak for once… ;) I think this story is rather tragic, for both of them… I'm kinda proud I wrote it, and I would never have gotten the idea if it weren't for the word 'Siren'…

Now I'd like you to imagine that Slade is wrong, that Robin really isn't this mythic creature, just a normal human being… interesting thought, huh? ;)
