Personally I didn't really like this one / Here you go anyway. I tried to write in third person but I don't think it worked. I promise the next one is better.

Normally I edit on my laptop, but I'm away from home, sorry for silly mistakes /

Alec was frantically bustling around the Pandemonium getting last minute decorations up for Jace's 20th birthday.

Although Alec battles demons every day and has saved the world on multiple occasions, he couldn't help feel nervous about this surprise party.

"Alec, has everyone arrived?" Magnus asked. Together, they were planning to organise the best birthday party.

The Lightwoods, Herondales, Penhallows, Carstairs, and many more families were invited, as well as people from the institute.

Alec checked her texts.

Everyone arrived at Magnus's apartment, ready to be teleported when ready.

XO Iz

"Yes looks like it," Alec replied. They had made everyone to go to Magnus's apartment to make setting up easier.

"Okay then, I think we're done," Magnus said.

They looked around the room for 20 seconds when Magnus squealed, "We need more glitter!"

Alec face palmed, "Magnus, we already have enough glitter to fill a shark tank!"

Magnus pursed his lips, "Well, we're missing a spot."

Alec narrowed his eyes as if to say, really?

Magnus suddenly pulled out his glitter gun, (Don't ask from where, he's a warlock), and sprayed Alec.

"You needed some sparkle," Magnus smiled innocently.

Alec groaned, "Why exactly am I your boyfriend."

Magnus gushed, "You know you love me."

Alec couldn't help but give that adorable smile.

Beep. Alec received a text from his phone from Jace.

Will be at the Pandemonium in 5. Brought an extra seraph blade for you.

Hold the demons off with your bow and arrow.

Jace

To lure Jace, Alec told him that there was a demon attack at the Pandemonium.

"Can you whip up the portal now," Alec asked.

Magnus nodded. He did some hand movements, and voila, a portal appeared in which everyone from Magnus's apartment came through.

The Pandemonium was suddenly filled with chatter.

"Okay, Magnus, get your blingy stuff away from the entrance, he'll get suspicious," Alec instructed.

"You think he'll notice the sparkle cannon?" Magnus inquired.

Alec glanced at Magnus with piercing eyes.

"The cannon has your initials on it," Clary said softly, "Might be a bit of a give a way."

Magnus groaned, "Fine."

With a click of his fingers the cannon appeared inside the Pandemonium.

Magnus smirked, "Wouldn't want to rune the surprise, would we?" He said staring straight at Alec.

Alec stared back with a blank yet amused expression.

"Did you just? Uh," Clary said awkwardly.

"My god," Izzy muttered.

Awkward silence.

"That was so funny Magnus, you're a hoot!" Simon chuckled.

Another awkward silence.

"What are we going to do with you Magnus?" Alec said while shaking his head.

"Guys be quiet, he's coming," Simon whispered. Perks of having a vampire friend who has super hearing.

In about a minute, the door creaked open until it showed Jace's face,

"Surprise!" everyone exclaimed.

Jace dropped his seraph blade dramatically, "Oh my god, this is amazing,"

"I know right? Alec and I organised it," Magnus said smiling.

"Oh you really didn't have to," Jace said, his arms wide open ready to hug Mag-, nope Jace just pushed past Magnus and went straight to his Parabatai, Alec.

"Your welcome," Alec beamed.

Jace looked up at Alec's head and noticed some sparkles, "Um Alec? You have glitter in your hair," Jace said.

"Magnus," Alec said simply.

"Right," Jace replied.

"What you guys waiting for? Let's party!" Magnus cheered.

The DJ blasted some music and glitter and streamers were falling from the ceiling.

Soon, Alec had lost Jace amongst the crowd.

While Alec was looking for Jace he found Izzy instead.

"Great party Alec," Izzy said.

"Thanks, have you seen Jace? I want to give him his present, it's kind of private," Alec asked.

Izzy looked around the club, "Haven't seen him,"

Alec frowned slightly. "But I have an idea," Izzy said, her eyes sparkling.

Izzy pulled a megaphone from god knows where and cleared her throat, "Alec Lightwood really, really sucks,"

Suddenly Alec could hear someone's voice in the distance, his ears perked up, "Who dare say such a thing about my Alexan-," and that's Magnus.

"Iz, wrong guy," Alec sighed.

"Just wait," Izzy said. Alec rolled his eyes, "3...2...1,"

Jace suddenly whirled up with his seraph blade, "Fight me!"

"See," Izzy said.

"It worked I just needed to get your attention, Jace, thanks Iz," Alec said.

"Oh," Jace said, dropping his weapon on the floor.

"Come with me, I want to give you your present" Alec lead Jace to a room out of the party.

He pulled out a small velvet box from his pocket and opened it. Inside was a golden ring with a diamond on top.

"So I've just been having this feeling that-,"

Jace's eyes widened in shock, "Um this was not what I was expecting, ugh what about Magnus?" Jace was baffled.

Alec just stood there dumbfounded for a few seconds then finally seem to catch on,

"It's not for us you bimbo, why would I want to marry you?" Alec said with distaste.

"Hey I'd be a very good husband," Jace retorted.

"Don't know about that one," Alec replied.

"Anyway, it's for you and Clary, I don't expect you to marry now, but as I was saying before, there's this feeling, I could sense it, you're...happier around Clary, yet nervous, and I knew you wanted to pop the question and as your Parabatai-," Alec rambled on and on.

Jace interrupted, "I love it,"

Alec let out a sigh of relief, "Thank god."

Jace looked at Alec, "What did I ever do to deserve you?"

Awkward ending I know haha.
