I: I'm here again! This is the final chapter, but there will be an epilogue. And, since today is such an happy day, our favorites boy decided to do the disclaimer without complaining.

Magnus: Liar! We didn't!

I: Yes, you did.

Magnus: We didn't!

I: *ultimate glare of doom*

Magnus: I get more scared by my cat when he's hungry.

I: *cute puppy-dog-face*

Alec: Aww! She doesn't own the mortal instruments series, or us.

Magnus: That's right, baby! Only I own you.

I: Here we go again.

Since we didn't want our apartment to get destroyed, Alec and I had decided against holding the wedding party there. We had settled for a large hall in the underground of the city, where we warlocks often held our councils. It had taken a couple of favors here and there to reserve it, but it really had been worth it.

The room was enormous, with a high ceiling painted with the personifications of the four seasons. A huge portrait of Hecate, the magic goddess, a blazing torch in her hand, hung on the wall. Other portraits, of the greatest warlocks and witches in history: Merlin, Circe, her nephew Medea, regarded us with stormy, painted eyes.

Of course we didn't want it to be too creepy, so we had dusted the walls and floor with blue glitter. I had wanted the tablecloth to be glittery, too, but Alec wouldn't let me, so it was just a plain dark blue. I had thought that Alec had realized the secret power of glitter, but apparently, I had been wrong. I still had to work a bit on that.

Metis smiled, grabbing my arm excitedly. "Mag, it's time for the fist dance!", she nearly screamed with a smile that I very much suspected to be sadistic plastered on her face.

I groaned. "Do we have to do this?", I moaned. Her grin got, if possible, even wider. This was going to be hard. "You don't have a choice, Mag!", she exclaimed gleefully, pretty much shoving me into the dance floor, so that I nearly bumped into Alec, who was already struggling to regain his balance, since, as he told me later, Isabelle had pushed him.

I took his hand gingerly, afraid of what would happen. Alec could twist and swing in an incredibly graceful manner when he was on a battlefield, but that grace would be hopelessly lost whenever he stepped on a dance floor.

We moved to the center, bright lights pointed on us, so that I had to blink several times to clear my vision. I carefully swung Alec around, as 'a kind of magic' started playing. Alec had insisted on that song. He claimed that it made him think of me.

To much my surprise, the dance wasn't a catastrophe. Sure, Alec was awkward and stiff, but he never stomped on my feet, he never accidently hit me with a leg or an arm, he didn't fall down… I was worried that someone had taken his place during the night.

As the song came to an end, and so did our first dance, I pulled Alec close and planted a firm kiss on his lips. He tasted of something fresh and pure, maybe water, but mixed to a vaguely intoxicating taste. Definitely Alec's savor. Well, now I was sure he was still the same person.

I pulled away from my blushing husband smiling. I was more happy than I had ever been in my eight hundred years of life. Alec made me feel like the luckiest warlock in the world.

I led him away from the dance floor, our hands tightly clasped. I pulled him into a dark corner and resumed our kissing, as the guests danced to song after song. Not even once they looked in our direction. Not that I minded, Alec was always way too embarrassed to make out in public more than strictly necessary.

"Since when can you dance?", I asked in between kisses. Alec pulled away and laughed, gasping for air. "I still can't. Jace helped me out with this particular song."

I cocked an eyebrow. "Jace can dance?"

"Surprisingly enough, he can."

"And he helped you for free?"

Someone laughed behind us. I turned. Jace was staring at us with a satisfied smirk. "Of course not. Jace Lightwood does nothing for nothing." I rolled my eyes. Could he possibly be more annoying? "I demanded to be paid back with his body." Apparently he could.

"You what?", it came out as a growl, even though I knew Jace was just messing with me.

"Shut up Jace.", Alec blushed, but his glare remained firm. He looked at me, and his sapphire gaze softened. "I just had to train with him four hours a day and buy takeaway at Taki's for him for a week.", he paused. "Isabelle was cooking.", he added meaningfully.

If Jace had been a bit nicer to me, I probably would have pitied him. But he hadn't, and he deserved the torture. "I thought your mother was home."

"She refused to cook until Robert was back to normal.", Jace explained, glaring at me.

"Abut that…", Alec sighed, "You promised you would turn him back after the wedding."

I groaned. "I hoped we could postpone it to after the honeymoon."

Alec smiled and shook his head. "A promise is a promise, Magnus. Come on." I sighed and snapped my finger, conjuring Bob and his bowl. "Please, Alec, he's so cute this way! I'd miss him.", I whined, hugging the bowl to my chest. "He never speaks, he never tries to hit us and he never insults us… He's the perfect father-in-law!"

Alec didn't say anything, he simply turned and walked towards the restroom. I followed him, pouting.

When we reached our destination, I quickly put the bowl on the floor, fishing in for Bob. I winced at the contact with the icy water, as my fingers clasped nothing for quite a few times, till I finally lost my patience and snapped my little, glittery but terribly annoying fish-in-law out of his goddamned bowl. I let him float in midair, ignoring his struggling. I snapped my fingers again, letting the sparks float trough the air. They circled Bob gingerly, but they began dancing around him in a steadily quickening pace. Soon, he was completely covered by them, and his shape started to shift.

In no time, we had in front of us a very much glaring, very much flushed, very much human Robert Lightwood. "Hi, Robert. It seems like we're family now.", I smiled sweetly at him. Robert sneered, trying to step forward. He lost his balance and fell on his knees, a surprised expression on his face. "You'll need a while to get accustomed to walking again.", I informed him, "Stay here for a bit, I'll tell your wife where you are." Then, I proceeded to snog Alec's brains out. He probably was too stunned to push away. I took his hand and wrapped an arm around his waist. We walked out of the restroom like that, holding each other close. Robert's angry screams where soon covered by the music.

The rest of the party was a blur. All I can remember is Alec, arguing with Jace, Alec, gossiping with Isabelle, Alec, glaring Raphael's undead life out of him because he was checking out my sister, Alec, scolding my sister for not minding Raphael checking her out, Alec, cutting the cake… Did I mention Alec?

Anyway, there is just one more thing I can clearly remember. Alec and I had decided to go away, sure that everyone was drunk enough not to notice. He had gone off to say goodbye to Izzy, and to ask her to cover us if anyone actually noticed our absence, when a still sober Clary tugged at my arm. "Magnus, I need to give you my gift. I know you are leaving.", she said urgently. She reached into her old backpack, pulling out a folded piece of paper. She offered it to me almost hesitantly. I took it and opened it, reveling the sign carefully painted on it. It was as sweet as a flower, yet hard as steel. It was as strong as a sword, as indefinite as a word, as exotic as magic. I had no doubts of what it was.

I raised my gaze from the paper, my eyes searching Clary's face. "Will this make me mortal?", I asked slowly. She smiled sadly and shook her head. "Having the angel's blood in my veins lets me know a lot of things. One of this is: what is done cannot be undone.", she said softly. "It will not make you mortal, nothing can. But it will make Alec immortal.", she hesitated for a split second, then added: "Good luck." She turned around and left in a hurry, not giving me as much as a last glance.

I looked down at the rune in my hands. For the first time in weeks I questioned if it was the right choice. Asking Alec to become immortal, to watch his family age and die, while he never changed. I could burn the rune and Alec would never find out about it. 'What is done cannot be undone'. I knew the meaning of that sentence. The real meaning. The moment Alec would mark his skin with Clary's gift, it would be forever. The mark would never fade away, it would never become another pale scar on Alec's skin. There was no going back.

I folded the piece of paper again, hiding it in my pocket. I could think about it in the morning. This was our first wedding night. We had already taken too many final decisions for one day.

I: So, how was it? Good? Bad? Let me know! Reviews make my day! And, yeah, I chose 'A kind of magic' by Queen for their song. I thought it suited them.
