Walking into her house with an invisible stranger was weird. Luckily she always opened doors really wide when going through them so Jace was able to slip through as well. It was past 10, and her mother hadn't stayed up for her that night. Audrey locked the front door behind her and led Jace through the house to her bedroom.

"Sorry it's so messy," she said before turning on her light, illuminating her room which was in a state of almost disaster. She hung her work bag on its hook and started to clean off one of the beds in her room for Jace to use. Jace stood in her door, watching and observing. Audrey's room was not very big, but not very small, with light pink walls, a light purple ceiling, and hot pink trim. She had a window facing south, with her desk to the left of it and her bed to the right. She had stuff hanging on every wall, from Volleyball to Lord of the Rings to nature posters, pictures of various people and places she had been too. She had one band poster from a special concert she performed at and a beautiful painting of a girl and wolf in blue monochrome on her wall as well.

"So, I can't pull out the trundle, because then my family would wonder what's going on. I hope you don't mind" Audrey said, snapping him out of his reverie. He smiled at her concerned face.

"I don't mind," he said reassuringly. She didn't look very convinced, but she let it slide. She walked over to one of her dressers and pulled out some pajamas.

"I'll be right back, feel free to make yourself at home," she said and walked into the bathroom to change. She brushed her teeth and went to back to her room to find Jace lounging on the trundle, asleep. She smiled gently, spread out a blanket over him, quickly brushed her hair, turned off the light, and climbed in bed. But she couldn't fall asleep. She was still reeling from the knowledge that the stories were true. They are true! Clary, and Isabelle, and Simon, they are all real. she thought. So are Sebastian, and Valentine. But you have to take the good with the bad. That means demons are also real...I can't believe I get to be part of this world! It seems like something that would only happen to someone else. With that, she fell asleep, feeling blessed beyond compare.

A shout woke up Audrey a few hours after she fell asleep. She drowsily turned over in her bed and raised her head to glance at her alarm clock. It was 1:30 am. Her head dropped, but she remained tense, waiting for the sound that woke her in the first place. She waited, straining to hear anything out of the ordinary, but hearing nothing unusual. Just as she had started to relax again, there came a muffled crash from the basement. She froze, and sat up slowly in her bed. She could just hear the sounds of a scuffle coming from below her feet. Steeling herself, she slowly and silently swung her legs over the edge of the bed, and crept out of her now open bedroom door, and peered out. She saw the basement door slightly ajar when she clearly remembered it being shut when she went to bed earlier that night. Trying to stay as quiet as possible, she slowly approached the stairs to the basement, which she proceeded to tiptoe as best she could down to her basement. From one side she could see a strange white light gleaming from under the cracks around the door, which also stood slightly open. She successfully made it down the stairs, apparently without drawing any attention to herself. She looked into the room that held her families washer and dry, her dad's workbench and tools, and her mom's sewing area. What she saw caused to freeze up even more. Jace stood with his back to the door, with two blazing objects in his hands - a witchlight and a seraph blade- facing a demon. The demon was tall and scaly, with an elongated human-like body and glittering ruby-red eyes full of anger. It was hissing at Jace, revealing a mouth full of pointed teeth that jutted out in every direction. Its arms were long, and serpentine, ending in eel-like heads. Audrey recognized it from the 4th Mortal Instruments book, The City of Lost Souls. A Vetis demon.

What is one of those doing here?! she screamed in her head. She subconsciously put her hand out to steady herself, but it met the open doors, causing her to fall forward into the room with a slight squeak, the door swinging open with a bang. Both shadowhunter and demon paused, and Jace turned slightly, to look at the cause of the noise. Audrey glanced up from the ground where she lay, straight into the eyes of the demon, who grinned evilly.

"Well now," it rasped with a dry chuckle, "there is no need for us to continue this fight. The girl is here, I will go now, and she will come with started forward with its arm starting to stretch out towards her when Jace lept in the way.

"She's not going anywhere," he said firmly. The demon hissed again, louder this time. Audrey couldn't help the small shush that came out of her. The demon stared at her, appalled.

"Jace, my family. If they hear anything…" she started, needed not go any further, for Jace, using the demon's distraction, swung his blade with a bright flash, slicing off the demon's head. He turned back to her, as the body and ichor vanished, leaving nothing but the mess of the basement behind. Audrey tucked up her legs, grateful that she had decided to sleep in her sweat pants, for the concrete floor was freezing cold under her hands and bare feet.

"How did you get down here so quietly?" Jace asked. "I didn't hear anything until you fell into the room." He held his hand out to help her up.

"I learned how the Native Americans used to walk when they were hunting. It has always worked better when I don't have anything on my feet," she explained as she grasped his hand and got hauled up. She glanced around the room and sighed.

"What?" Jace asked, a tiny bit of worry creeping onto his voice.

"How am I going to clean up this mess?" she muttered in response, putting her hands on her hips and shaking her head, overwhelmed by the caliber of disaster the fight had caused. But Jace just chuckled and clapped her on the shoulder.

"I'll take care of it. Clary created a rune that put her apartment back together and showed it to me. I'll use that. Watch." He took out his stele and drew the rune on his forearm, and waved it gently through the air. Audrey watched as everything was fixed and put back in its spot.

"Shall we?" Jace asked when he was done, gesturing to the door like proper gentlemen and butlers do in movies and books to lead the way. Audrey smiled and they walked back upstairs to her room. closing all the doors behind them. Climbing into bed, Audrey couldn't help remarking,

"Well, that was an interesting and terrifying way to start the day. I wonder what is going to happen next?"

"Sleep is." was Jace's reply. Laughing, they both curled up and went to sleep.
