The blood had washed from her body; she had to leave no evidence behind. If the institute found out she killed somebody, she would be in big trouble and it would mean imprisonment, but knowing her kind, they would stop at nothing to find her.

Standing outside the institute, she felt a presence behind her.

"How did it taste?" the womanly tone spoke. Turning around, she saw her sister, Clara.

"Like blood tastes like, what do you think?" She spoke sarcastically towards her.

"You know what I mean, Lexi" Clara smirked walking towards her sister, standing in front of her. "You could leave the Shadowhunting world, be free as a Siren, swim the Atlantic or the Dead Sea"

"Clara, as much as that sounds amazing, I can't"

"Why?" she asked, confused by her sister's dedication for the Shadowhunting world.

"Because I am part Angel, I can't ignore that. I am trying to prove to people I am good, but I can't do that by choosing to be a Siren" she explained looking down "I have to sign the accords, and if I run away and don't do that, they know we exist, and we could be potientially be a threat to them, I can't let that happen"

"Let me ask you something...do you enjoy being a Shadowhunter?" Clara asked, her facial expressions showed she was generally worried about her sister.

"Honestly? No, I don't. Since I was a toddler, I've been preparing to be a fighter, instead of having the freedom, we can't go out on the streets and blend in, because we stand out because of what we are. Compared to being a Siren, there is freedom, but we still are not normal, we either have a future with someone or we don't, being a Shadowhunter is about pleasing everyone else, hence why Alec nearly married Lydia"

"Do you forgive them yet?" Clara asked

"No, I don't forgive him, I won't ever forgive him, but I am willing to forget and move on"

"Is that why you killed that man?" she asked "Blowing off steam?"

"Exactly, and I don't want it happening again. Alec obviously wasn't happy with me, I don't know if not knowing if I was a Siren contributed to that"

"He didn't have the balls to tell the truth, you're beautiful, talented and you're an amazing person, Lexi"

"Clara you have to say that, you're my sister"

"I'm saying that as a friend, maybe you should move on"

"I wish I could, but I can't. I just...haven't got the heart to move on, like there is something blocking me"

Clara looked at Lexi, her facial expression turning into a surprised one, before her sister had a smile plastered on her face.

"Why are you smiling like the Joker from Batman?" Lexi stepped backwards, raising her eyebrow.

"He's the one" Clara whispered

"Say again..." Clara was silent for a few seconds before taking her sisters' hands.

"Like wolves, they find mates, they stay dedicated to their mate for life, for us Sirens, instead of calling it mates, we call it what mundanes call it, the one. Alec is the one which is why you can't move on, it's like you've imprinted on him"

"That doesn't sound good"

Clara laughed before shaking her head "You may hate him, and you two may not be together, but you will, trust me" she smiled, pulling her sister in for a hug "Don't give up; you have no idea how lucky you are to have someone. I know I wish I could find someone, but I am a True Siren, we find it best to not have a male in our life"

"I wish I could listen to my heart instead of my head" she sighed feeling warm in the hug. "I have to go, Isabelle is waiting for me" she said, watching the raven head girl at the institute doors.

"We will always be watching you, I know how creepy that sounds" Clara joked before pulling away before stopping, she turned around looking at her sister "It won't be your last kill, trust me on that" she smirked before walking off.

"I prefer you when you're a sister towards me and not a crazy True Siren" she mumbled to herself before walking up to the doors

"Where have you been?" Izzy asked

"Needed to cool down" she said pushing past her and walking into the main room

"You know they still want to arrest you" she informed her

"If they want me to sign the accords, arresting me for nothing, it isn't going to get us anywhere" she sighed walking past Alec and Lydia. Alec suddenly grabbed hold of Lexi's arm, stopping her in her war path. "You shouldn't do that" she said

"Gonna hurt me?" he asked, raising his black eyebrow. Tugging her arm away she looked at him.

"You're not worth it, Alec. I'm tired of fighting; I need my bed before anything else"

"You're still out for arrest, Lexi" Lydia spoke up

"Are you still here?" she asked "Wasn't the wedding being cancelled a sign for you to bugger off?" she asked

"I would advise for you to not talk to me like that" The blonde suggested

"I would advise for you to not piss me off" she warned, before Izzy frowned at her Parabatai

"Lexi...you're eyes" Izzy whispered. Lexi frowned before turning around where mirrored wall stood. Her eyes silver like the moon. Taking a deep breath, she closed her eyes and calmed down, before turning around and facing them.

"I can't control it sometimes, especially when I have to talk to people I hate" she said

"What is wrong with you?" Alec asked "Jace has been taken; we need to focus on that"

"Jace chose to go with Valentine, and don't you dare ask what is wrong with me! I saved everyone's life and this is the thanks I get? You kissed me and now you can't stand me, it's like we are going back to where we started, and I can't stand it! The fact Clara thinks you're my so called mate" she laughed to herself "If I could leave forever, I would, because I can't stand fighting anymore!" She took a deep breath before sighing "that felt really good"

"What's that on your ear?" Lydia asked

"What is on my ear?" Lexi asked. Alec moved her hair behind his ears before wiping it off and smelling it

"Blood, why do you have blood on your ear?" Alec asked frowning.

"I was blowing off steam" she said before walking off towards her room. Sitting on her bed, she looked at her broken door "gotta fix that" she sighed, Izzy appearing in the door way.

"You killed someone didn't you?" she asked

"He was homeless, had no family, I just...had to, she kicked in"

"She?"

"I refer my siren side as she"

"Was it only one?"

"Yes, and I won't do it again...probably, I don't know okay?" she told her sighing looking down "Please don't tell anyone" Izzy let out a sigh before nodding

"I won't. We are being visited by the Clave regarding the whole Jace thing, so get into some fresh clothes and meet us in the main hall" she smiled, leaving Lexi to do her thing.

After getting into some fresh clothes and showering before, she headed to the cluster of people standing in front of the Clave.

"You good?" Izzy asked

"Yeah" she smiled, before Alec glanced at her

"Decided to join us then?" he asked

"I'm making an effort"

"Where did the blood come from?"

"Papercut, drop it Alec" she warned before a man stood forward; a black man, with a rune on his neck, wearing a tight suit.

"Jace Wayland is now considered a traitor; we are putting a warrant out for his arrest, alive or dead. But now the Institute is on lock down..."

"That's not good" Lexi mumbled.
