"Here's the bathroom. You'll find fresh towels and everything in the cupboard in there. And there's plenty of drawers for clothes and weapons and whatever else you may have." Clary said looking over at Jace after placing his suitcase outside the bathroom door.
"Thanks Clary and what else do you think I have?" He laughed as he pulled a dagger out from his weapons belt.
"I didn't say anything. Now if you'll excuse me, I'm going back to train. If you're smart you'll listen to what I'm going to tell you." Clary raised an eyebrow and stared at Jace, "DO NOT interrupt me when I'm training for anything. You understand? The last time someone did, they nearly got killed. So my training hours are from six till seven, but because I've been interrupted I'll be in there longer." Jace nodded and said, "Don't worry, I won't interrupt the elf in training." Clary, mouth open wide, shut it before she could say something she'd regret.
"You better watch it Herondale." Was Clary's reply and she stormed out of his room slamming the door behind her.

Still fuming from what Jace had said to her, she went into full on kill mode and no dummy survived. About twenty knives were now destroyed too due to the fact that whenever she was in kill mode she almost caught on fire. This was because of the angel blood within her and it completely took over any knife that got used. All twenty knives were thrown with such power and anger that each one caught fire; this, was Clary's downfall. Even when she was training with family and friends she couldn't control what happened, and unfortunately, she'd hurt many people with this fire within her. Suddenly, she heard the door open and without knowing, she threw two of the three knives that were in her hands.

Jace wasn't expecting what just happened and he felt shocked at what Clary had just done. But then he felt blood trickle from his ear down onto his neck.
"Clary! What the hell?!" Jace shouted. He was usually the one on the throwing side of things and no girl shadowhunter, apart from Isabelle when training, had thrown a knife at him.
"Jace! I could ask you the same question, I told you not to interrupt didn't I? Or are those big ears of yours too blocked to hear what I said?" Clary shouted back at him.
"Aren't you going to say sorry? I mean you could of killed me." Jace stood at the door tapping his foot completely oblivious to his cut ear. Clary didn't know quite what to say so she just smiled and carried on training forgetting he was there. She did multiple back flips throwing knives at dummies as she did. In the end, she jumped using all her power and landed on the highest balancing beam that the Institute had. No one else had managed to get up onto the beam so Clary liked to show off whenever she could, and now was the perfect opportunity.
"If you don't mind," Clary started to say, "can you shut the door on your way out? Thanks." Jace had annoyed Clary so much but there was something about him that appealed to her and she couldn't quite put her finger on it.
"Sure." Jace said sounding disappointed. He walked out of the training room and shut the door behind him. He walked back down the hall to his room and there, standing outside, was Alec.
"Alec, what are you doing outside my bedroom? There's not a threesome going on in there is there? Because you should probably tell me if there is." Jace laughed at his joke and opened his bedroom door. He walked in and went over to the draw where he had put his weapons.
"What are you looking in there for?" Alec said walking in after him.
"Well I nearly got killed so I think I need some protection on me at all times with that little elf around." Jace replied putting two daggers into his jacket.
"Wait what? You almost got killed, how? And who's 'that little elf'?" Alec questioned.
"Well she did warn me it would be a bad idea to go to the training room when she was in there. And by 'little elf' I mean Clary. I suppose I should have listened if I didn't want my ear cutting." Jace said pointing to his ear.
"Is it bad? And how exactly did she do it Jace?"
"Well, I walked in and obviously she wasn't expecting to see me and the next thing I knew, two knives were coming towards me. I didn't have any time to react they were thrown so fast, but luckily, she missed and one of them only caught my ear. It's fine now though, no need to panic. But the weird thing was, the knives were on fire when they flew past me. I don't know why; I may need to find out about that for future reference." Jace explained whilst changing his shirt due to the blood on his collar. He put on a fresh navy blue shirt that made his skin look even lighter than normal.
"I've never heard anything like it. And yeah, finding out what that was is a good idea. Knives on fire? How strange."
