A/N: A new fic I came up with where Jace has random encounters with ducks. Because, let's face it, Herondales and ducks are every TMI fan's favorite encounter.
Walking towards the New York Institute, Jace had an extra spring in his step. The blonde curly-haired teen defeated a pretty decent amount sized demon horde singlehandedly. Izzy and Simon were off doing who-knows-what, and Clary was busy shopping with Luke and her mother. Alec had spent the night with Magnus, and his parabati still was out with the glittery warlock to Jace's knowledge. His hazel orbs shining with happiness and contentment, he proudly strode down the pathway of the park, taking a scenic shortcut just because. He was glamoured, so he was pretty much invisible to everyone and everything; or so he thought. Suddenly, he heard a noise that made him scream. A small, feathery being stalked its way up to Jace, its brown eyes staring straight into the shadowhunter's gold orbs. Reaching for his seraph blade, the duck took a few more wobbly waddles that had Jace quickly back-stepping.
"Stay back you foul ferocious beast." He shouted at the plump little fellow, the duck ruffling its feathers in response. "I know what you're trying to do. It's not going to work. You can't trick me you demon creature." He continued yelling at the duck. Slowly, the duck took another few steps towards him. "Get back! Back I say you evil monster." His hand shook, the seraph blade trembling in his grasp. His eyes searched for help, however inwardly he cursed himself for using a glamour. Several people were around him, who could help him, and yet here he was, invisible to anyone aside from a Shadowhunter or Downworlder. Knowing he was trapped, he took out his phone, unlocking it without looking and clicking a random number. "ALECIMINTROUBLEANDINEEDYOU!" He screamed into the phone, the duck advancing and him stumbling back. Jace Herondale never stumbles, but a duck is a demon he is unable to face. The duck was quickly gaining speed and Jace took off, dropping his seraph blade in the grass in the process. "Alec! A duck is chasing me! He's going to kill me!" Every time he stole a glance over his shoulder, the duck seemed to be staring and charging straight at him. He jumped over a park bench, and he kept on running. And he ran right into his parabati's chest. Scrambling back a half-step, Jace launched himself behind Alec, using the black-haired teenager as a human shield. Alec took one look at the duck behind Jace and sighed.
"Magnus." The glittery warlock clapped his hands and the duck vanished into a puff of smoke.
"That is one thing I will never understand."
"What?" Alec questioned, curiosity clear in his crystal blue eyes.
"Herondales and their ducks." Magnus laughed, shaking his head. "No matter how chivalrous and egotistical they are, one look at a duck sends them running and screaming the opposite direction." Jace scowled from where he was cowering behind Alec.
"Ducks are vicious monsters created for torture devices and should not be taken lightly."
"Will once said something similar to that." Magnus mused, amusement dancing in his amber cat-like orbs. "Although his reproach towards a duck was to have Tessa kill it."
"Well she should've! Ducks are mean. We must rid the world of them."
"Jace, shut up or I'll have Magnus bring it back along with some of his duck friends." Alec shook his head in annoyance.
"You wouldn't." Jace gasped, his eyes widening with terror.
"Can we please get back to our date now?" Magnus said with a pout, his fingers caressing Alec's left cheek and his palm resting against the shadowhunter's chin.
"I'd like that. Jace, go home. The duck is gone." Jace glared at the two of them, stepping away from his raven-haired parabati.
"It better be gone. Stupid duck." Alec heard his golden-eyed goldilocks-like parabati mumble under his breath as he retreated quickly through the park and out of sight, no doubt going back to the Institute.
"Where did you send it?" Alec asked his boyfriend, watching an amused smile spread across the warlock's face.
"My apartment of course. Who knows when my handsome blue-eyed shadowhunter boyfriend may need a duck around to keep the egotistical Herondale out of his hair?"
"You're evil." Alec laughed out, running a hand through his tousled jet black hair.
"Not evil, incredibly smart and sexy. Yes, I much rather prefer that. Smart and sexy...it has a nice ring to it, don't you think?" A blush crept up Alec's face, the delicate pink contrasting with his already pale complexion. "Now, where were we?"
