The twins haven't always been evil, they arn't evil in fact they have never killed any one. They just act tough, because that's the way the supernatural thing works. You are either on top of the food chain or the bottom, and they were always on the bottom of it, it all started from the moment they were born. Their life was turned upside down that was the start of all the mess.
Ethan is not a bad guy he's not, well not really, he's a werewolf he has animalistic instincts but he never ment to hurt any one. It was Deucalion that had made him a killer. What he and his brother can turn into is rare, they were born like that they killed there mother from the inside, and she was a born werewolf the injuries were that severe she couldn't even push. They had to be cut out by their mothers emissary. Their father was human and he didn't know how to look after any child, let alone two werewolf children.
Their father begged their mothers emissary to take them in, and he did and he found them a small pack that were glad to take them in and glad for the additions. They were their family for 10 years then the unthinkable happened.
They were asleep when they heard the sounds of gun fire and screaming. Their alphas mate, came rushing in and told them to merge and take off in the sewers, and hide there until someone came and got them. She told them to stay merged because they were much stronger together.
They sat in the sewers, and the smell alone was enough to nearly incapacitate them. They could hear the screams of the pack above ground, the hunters chanting and laughing saying horrible things. As they sat their together merged they were stronger, but what they never told anyone is that should they feel pain in this form, its a pain that doubles one for each person. They sat down their crying they could feel the pack bonds being severed, and cord like tether that was representing each member of the pack. With each loss they grew weaker, and it felt like a limb was being ripped off. They could hear the cries the screams and the roars, but then nothing the sounds went away. The next sound was the sound of their scream. the burning power being thrust into both of them the sheer agonizing pain. They didn't know what it was. The next thing they remembered was waking up covered in the sewage. They were the only ones that remained of their pack. And some how the impossible happened. Because they were merged the power of the alpha that was supposed to go to Aidan, because he was the oldest by 2 minutes, but still that's how it went. But it didn't, because it split in to the two of them. Both of them got the power of the Alpha, but both of them hated being werewolf's. They killed their mother, whether it was an accident they had no controle over, they still blamed themselves. Now they were in constant danger because they were weak untrained Alphas, now people will see them as easy ways of becoming Alphas.
They decided to travel, they had no one left no pack, no family, they only had each other. So they traveled throughout America, for Months stealing and scrounging for food hiding out whenever and wherever they could. They stayed mostly in the California area because it was warm, and their was beaches no one could kick them out of a beach. It was their that they met him, he promised to protect them, train them and keep them safe. They thought they could trust a fellow Alpha, and they did up until their 14th birthday. Duke, Kali and Ennis where always secretive, it was that night that they seen them kill, they saw them slaughter so many over the years after that night as well. They tried to leave but they weren't allowed Duke said they were pack and the only way out of it was death, and they wished for 2 years that death would come.
When Derek killed Ennis and the Darach killed Kali and Duke went to wherever the hell he went, they were free for the first time but it came at a cost. When there necks were snapped not only did they loose the ability to merge, but they lost their Alpha status. Which wasn't that bad if there being honest. Because they never wanted it in the first place. They became Omegas and with much pleading. on their part and a lot of begging Scott and a couple stern words from Lydia, the new true Alpha accepted them into his pack, so they could become betas again.
Which links us back into the now. Danny, Danny was always the mission. Ethan was always bullied for being Gay, by the whole of the Alpha pack. Being told to get close to Danny was nice he made him feel normal liked even. He always accepted him, for what he was on the inside, not the supernatural side to him. Even if he doesn't know anything about the supernatural. But he didn't love Danny, he liked him sure but in the hall in the mornings, its not Danny that catched his eye, its not Danny he thinks of when he takes care of his morning wood, its Stiles, the beautiful human. That has a heart of gold, and when need be back up he's their. Even though he hasn't got any powers to speak off he's beautiful in every way shape or form. He wants Stiles there are however a few things wrong with that.
1. He's still with Danny.
2. Stiles, doesn't trust him, even if they are in the same pack.
3. He's not even sure if Stiles is gay, he's caught him starring at a few boys in the locker room, but that could be just admiration of the human form. The boys on the team are hot, except Greenburg
Its going to be hard to do something about it, but every time he smells Stiles gorgeous sent, it makes him want to lick him all over. He's falling for the spastic teen its not his fault. But every time he sees Stiles, flirt with someone, or someone touches him both him and his wolf want to howl for Stile's attention and strike., whoever is doing the some reason both him and his wolf are protective of the teen they both need, and want him with them, they both have to have him as soon as possible.
The first thing and honorable thing to do is to tell Danny the truth. He still cares for him but he's not the one that he wants, he needs to start over, on a clean slate. Especially with Stiles and he really needs to get him to go out with him, But that's harder, done than said.
