DISCLAIMER : I do not own any of the characters or original plot of The Mortal Instruments.

This one is just about Jace training Clary and it is mostly fluff. This one-shot is kinda short but uh enjoy!

Clary POV

Right now I am speed walking to the training room. I overslept and am an hour late for training with Jace. I push open the doors and scan the room for Jace.

"Nice of you to show up" His voice comes from the corner of the room where he is lifting weight.

"I-... I'm sorry… please don't be mad"

"Clary, it really isn't a big deal just don't make a habit out of it."

I nod and ask him what is on the agenda for today.

"Well since you were late you're gonna have to do some running."

"Come on Jace, is that really necessary?" I exclaim.

With a smug look on his face he says "Better get running the timer started."

I start my laps around the large training room. I understand why running is important, I need to build stamina. Sometimes Jace just has this cockiness when it comes to training. It comes off as condescending sometimes but I know he is just trying to make me better.

I finish the running and put my hands on my knees while I try to catch my breath. Jace walks over to me.

"Ready to fight?" He asks.

"Fight who? You?" I reply with a laugh. Jace is about ten times the shadow hunter I am. I keep laughing until I see his golden eyes are serious.

"Clary, I need you to be prepared the best you can. I know you don't think you're ready but I'll go easy."

"It's not like I'm gonna have to ever fight you." I protest.

"We have been in far more unusual situations so never say never."

I decide to keep quiet. Jace counts down starting the fight and I try to think of what the best first move would be. If only he wasn't so much taller than me. I go for a punch but he catches my arm and twists it behind my back. I use my other elbow to hit his rib which causes him to let go of my arm. As soon as I steady my weight to throw another punch I have already been swept off my feet. Literally.

My body hits the ground fairly hard. It hurts. Jace pins me to the ground triumph in his face. I soften my eyes and pull his face down to meet my lips. He no longer has his guard up so I take the opportunity to flip our positions and now I am pinning him.

"See Jace I won"

He rolls his eyes in a playful way and says "Is your shoulder okay? You hit the mat pretty hard."

I push down the sleeve of my t-shirt and see my shoulder is already red and swollen.

Jace has concern in his eyes.

"It's nothing, I will be fine."

He gets up and extends his hand towards me to pull me up.

"I think Izzy is cooking tonight." I said.

He looks thoughtful and replies "In that case do you want Taki's?"

"Jace I think we should suck it up for one night because she is cooking enough for us too."

"You're too nice fray"

I throw on my sweatshirt and tell him I am going to shower. I hear him call out as the door closes "Without me?!"

—

I step out of the shower and aimlessly look through the clothes I packed. I don't have many options. I have training gear, pajamas, sweats and t-shirts. I throw on a pair of purple leggings that were crammed in the bottom of my bag and throw on a black sweatshirt over it.

I check my phone and see it is four in the afternoon already. I wonder what Jace is doing but I want to give him space. I know spending too much time together can be damaging to a relationship so I steer clear every once and awhile to give him some alone time.

Just then my phone starts vibrating and I see mom is calling.

"Hey mom, how is your honeymoon?"

"It is beautiful here. I miss you though"

I make my bed as I talk to her "I miss you and Luke too."

I can hear the tone of her voice when she says "I hope you are behaving yourself since the Lightwoods were nice enough to let you stay at the Institute."

"Of course I am" I said "I just finished training with Jace."

"And he's behaving himself too?" She asks. Clearly a hidden meaning in her words.

"Mom, everything is fine, really. Go enjoy your vacation."

"I just wanted to check in on you. Be safe, I love you."

I reply, "I love you too." And then I hang up and toss my phone on the bed

It's still hard to believe this is my life now. Obviously I'm not complaining, I love being a shadow hunter. I wonder if I will always feel like I don't necessarily belong here at the institute. Everyone here is trained and experienced and I am just starting now.

Sure I have my runes, that makes me valuable. But what if I didn't have that? Would I still be an asset, or just dead weight?

I realize I still have an hour before dinner so I decide to draw. I don't really know what to draw, I don't have any inspiration at the moment. I rack my brain for something to draw.

I think about Jace but I have drawn him too many times and they never come out the way I want him to. I most definitely am not in the mood to draw runes. I feel no inspiration. I feel empty today. I am constantly reminded of Sebastian and all of his damage.

Without thinking I am already sketching Sebastian's death. It should've been a victory. But I still felt like I lost someone I had never gotten a chance to know. I draw his body, and depict him as Jonathan instead of Sebastian. I draw myself grieving for the brother I never had. I draw mom upset and also grieving.

I look down at what I created. It's awful. Sebastian was a monster, why I am I still not over it. I never thought I would still be upset months after it happened. Frustrated at myself I throw my sketchbook across the room at the door still open on the page.

Almost at that same moment Jace walks through the door and sees my mood. He leans against the door frame.

'I should've knocked…is this a bad time?" He asks.

"No I'm fine seriously don't worry."

He doesn't look convinced. He scans the room and sees my sketchbook on the floor. He bends down to pick it up and flips it around so it is no longer upside down. I can't read his expression as he stares at the scene I drew. He tears his eyes away from the page to look at me.

I talk before he can say anything "Jace I don't wanna talk about it."

He clears his throat before speaking slowly. "Well, I think we should."

"I don't know why I feel upset." I begin. "He was a monster, he killed people, he killed our friends."

"You're allowed to feel upset, Clary." He spoke softly and kept eye contact with every word he spoke. "You aren't mourning for Sebastian, you mourn for Jonathan… and that's okay."

I exhale and give a small laugh "What would I do without you?"

He grabs both my hands before he says "I love you, come on let's go eat Isabelle's 'food'"
