Hello! You guys are lucky, I was done with work early today and in a great mood so I decided to upload the next chapter now! Hope you like it! Enjoy! ^_^

Disclaimer: I own none of the characters.

"Hey…" The Nephilim called softly seeing he was starting to panic again. "Calm down baby… I lied about not wanting to be immortal."

Magnus let go of a breath he hadn't realised he was holding, the tension leaving his body as he slumped back on the couch.

Alec ran his fingers on the back of his hand soothingly and started explaining. "I'm sorry… The truth is I want to be immortal. Of course I want to be with you forever! There is nothing I want more… But I knew…" He shook his head correcting himself, muttering. "Or so I thought…" Before going on, "I knew that it was impossible… So I didn't want to burden you with guilt and sorrow. I didn't want to make you blame yourself for not finding a way… If you thought that's what I wanted, you wouldn't torment yourself when I…" He trailed off and Magnus gasped softly shaking his head.

"No, no, no, no…" His eyes widened in terror as terrible images of Alec dying came unbidden into his mind. "Please, please don't say that…" He gripped his hands tighter moving closer, a pleading look on his, now-desperate eyes. "I can't bear to lose you… You can't die…"

Alec hugged him once more. "Hush…" He crooned. "Calm down Magnus… It's okay, it's going to be fine… As long as you want me I will be here… I'm not going to leave you… Hush…" He held him close running a hand soothingly through his raven hair until Magnus calmed down again, his breathing slowing. "Magnus…" Alec called softly when the Warlock slumped into his arms relaxing once more. "Tell me. What you found out. Tell me what needs to be done… What's the cost?"

Magnus pulled back to look into his eyes again and the Shadowhunter added. "No matter what it is. I'm going to pay it. No cost is too great to be with you forever." He said the words with conviction, being well aware that the few things he would be unable to do, he wouldn't have to. Magnus would never tell him about it if the cost was something awful for him.

He tried to think of what he couldn't do for him. There was only one thing coming to mind. Sacrifice his family's lives. Of course he couldn't do the reverse thing either. Magnus was his precious family too.

He was a little surprised himself to realise that he would even give up his marks for Magnus. He knew a mundane life would be unbearable for him. But he trusted Magnus and knew that together with him he would be able to do anything. After all, Magnus was willing to become mortal for him, and leave the life of magic he led for more than 400 years. What were eighteen years of Shadowhunting comparing to that? There were many other Shadowhunters to take his place anyway.

'You digress…' He told himself. 'That is not the price, and deep down you know it… Magnus would consider that 'awful' and keep everything secret to protect you…'

He shook his head to cast away all thoughts and looked at Magnus again. The Warlock was staring at him as if he couldn't believe what Alec was telling him.

And that was exactly the case. He was running the boy's words over in his head, trying to make sense, trying to understand how could he mean them. How could someone so beautiful, so kind, so amazing, so perfect… How could Alec, be really his'…

"No cost is too great to be with you forever." He had said, and Magnus wondered in awe how could ten words make him so happy. He had thought nothing could make him happier than hearing Alec tell him "I love you." But those words meant so much more. Not only that he loved him. They showed the extent of his love.

Many had claimed to love him over the years, but no one was as determined as Alec to prove it. To stay with him no matter what. To live with him forever, and never let him be alone again.

But the cost… The cost to do that was great and he found himself faltering. 'How can I tell him… How can I expect him to accept that?' He thought, while Alec looked at him expecting his answer.

"The cost…" Magnus whispered finally, after a few minutes of silence. "Alexander… No matter what, you are a Shadowhunter… It may be too much for you…"

Alec's eyes widened again momentary as he realised his former speculations were probably mistaken. Still, he steeled himself and told him, keeping his voice steady. "Please tell me."

Next update tomorrow! Hope you like it so far!

Note: I know Alec's eagerness to become immortal is supposedly OOC but I don't care! Not even a little bit.

I don't understand why he wouldn't want to be immortal and be with the love of his life FOREVER! As Alec said here, maybe he said he didn't want to be immortal and was accepting the cruel fate because he believed there was no way to be immortal…
