Author's Note: Someone told me that this story can be a little confusing because "Alec was not an angel to begin with". Well he is a Nephilim, Nephilim are mortal descendats of angels, which means that he has angel blood in his veins, not as much as Jace, but still he has it. The fact that he turns into a Fallen is obviously my idea and I did not mean the term "Fallen" as you can mean it when it is referred to Lucifer.
Let's just say that I conceived this group of Nephilim which chose the "evil path".
This is one of the reason why this is an AU.

Someone else wrote that Alec would never ask for being Turned in order to be immortal, that is unmistakable true, but what in this story he did not asked of being turned to be immortal, he was ready to die when Simon found him. He asked Simon to Turn him because he knew that otherwise they would have brought him to Magnus (or Magnus to him) and Magnus would have died to save him no matter what. Besides if Alec had died Isabelle would have been in pain once again she would have lost another brother.

By the way thank you for the reviews I really appreciated them, and of course I don't own any of the characters.

Just for a moment Alec thought he was about to gasp, than he remembered he was no longer a breathing creature and together with that realization came the awareness that he didn't care what he was, he had made a choice and would stick to it no matter what.

-What does it mean he is one of the Fallen?- Jace asked still staring at his brother.

-The Fallen are damned Nephilim, or this is the way Nephilim describe them. Did you never pay any attention during classes?- Alec answered without moving away from Magnus who seemed too shocked to react.

-I know who they are, but you were bit by a demon and ended up on of the Fallen, that doesn't make any sense, Alec!-

"It would be better if we all sit, don't you think Magnus?"

The warlock nodded and kept and arm around Alec shoulders while they moved to the sofa.

"Alexander would you please tell us the whole story?" Brother Zacariah asked politely.

Alec sat between Magnus' legs, the warlock hugged him from behind and his chest leaned against Alec's back. The two men had their fingers entwined.

-As I said I was reckless, I went out hunting alone and the demon I was fighting bit me. I was bleeding to death in an alley when Simon found me.- Simon made an uncomfortable noise, but did not interrupt. -He told me he would bring me to the Institute, when I explained there was not enough time for that he insisted into bring me to Magnus and let him heal me and I refused.- Jace's eyes were wide with disbelief.

-You did what?-

"Jace!" Brother Zacariah's voice broke up into their mind and Jace went silent.

-I refused. If Simon had brought me to Magnus, he would have healed me and he would have died in the process, I was aware of the seriousness of my wounds.- Alec's voice raised just a little and in his eyes flashed with a spark of silver.

-I asked Simon to Turn me, that was the only way for me to survive. He tried to make me change my mind, but I did not so he was forced to Turn me or let me die, and he swore he would never let me die. When I woke up, I was in Magnus garden, I was not thirsty and when we came up here, we found out my Marks apparead like this.-

The Warlock kissed Alec's hair tenderly. No one was talking, the silence seemed heavy and concrete, until Jace stood up in one movement

-You ask a vampire to turn you? What the hell were you thinking Alec?-

Alec's blue eyes widened in disbelief at his parabatai's angry words, but this time he didn't feel ashamed of anything, he felt... angry, angrier than he had ever felt before

A strange sound came from his throat, it seemed a hiss but his voice came out as soft cold whisper.

-What were YOU thinking when you ran away to find Sebastian by yourself back in Idris, what were you thinking when you hid the fact that you have died to all of us, what were you thinking when you didn't tell us about your nightmares? What were you thinking back then Jace? I guess you were not thinking at all, you were just going on your way and never once thought that your problems would turn into our problems eventually, because that's the way you are: a reckless pretentious fool.- Alec was standing by the time he had finished his speech, his eyes shone silver, any track of blue completely gone from them.

Jace had moved a step away from him, he had never heard his parabatai talking like that.

-I'm sorry.- He whispered awkardly.

Alec smiled before feeling his strenghth leaving him altogheter and collapsed.

-Alexander!- Magnus screamed taking him into his arms and rocking him back and forth saying his name.

-Conjure some blood he needs it, now.- Simon who had been silent till then finally spoke, and Brother Zachariah put a long pale hand on the black hared shadowhunter's forehead.

"He is exhauted, he needs some energy. The Daylighter is right."

-I'll give him mine!- Jace had his sleave already put back, but Brother Zacariah stopped him, Jace would have never thought that a Silent Brother could have such a strong grip.

"Heavenly Fire is running through your veins, you would destroy Alexander if he drank your blood."

Jace face went completely blank as he stared at his best friend face.

Magnus snap his fingers and a little dagger appeared out of nowher in his hands and without a word the Warlock cut his own wrist.

-Drink, my love, my Alec.- he whispered. The blood tainted Alec's lips and rapidily slipped down. Little by little the boy started to drink but he stopped when his eyes flew open and he realized he was drinking Magnus' blood. He seemed to choke but suddenly grasped the wrist the Warlock was keeping near his mouth and drank greedly never leaving his lover's eyes.

It took no more than a few minuts for Alec to move away from the blood and kissing Magnus' wounded wrist, immediately the flash appeared healed and the Warlock exaustion seemed to disappear.

-What did you do to me?- He asked softly.

-I shared my strenght with you, Iguess.- Alec bent his head down shyly.

Jace was about to speak again when Simon gave him a fiery glance and moved towards the blond Shadowhunter.

-I know you hate me, but you've to understand that Alec would have gone for good if I hadn't accepted to Turn him.-

Jace felt an annoying limp in his throat and found himself unable to speak, he just nodded and looked at Alec again.

Magnus had his arms wrapped around Alec's body and his face hidden in his black hair, and Alec was smiling at the Warlock a whispering soothing words Jace couldn't hear.

-Should we go back to the Institute?- He asked Brother Zacariah.

"If you think that this is the best thing for you to do, yes we can go back."

Alec turned his head to face his parabatai.

-Jace.- He called softly. -Tell Izzy I am all right, please.-

The Shadowhunter nodded quietly.

"Magnus you can always call me." Brother Zacariah told them and followed Jace out.

-How do you feel?- Magnus asked clearly worried keeping an arm around his boyfriend shoulders.

-Fine given all the dead and reborn matter.- He smiled.

Simon absent mindly took the last empty cup from the coffee table and moved to put it away when he felt someone touching his arm lightly, when he turn around he saw Alec, his head cocked on one side and a thoughtful expression on his face.

-Izzy will be grateful you Turned me, she could have never survived to another brother's death, you saved her too.- He smiled a little.

Simon stared at Alec's blue eyes just for a second.

-Thank you.- He whispered.
