Summary
     What will happen when Clary has a vision of a rune in Sebastian's
     last moments? Can she use it to save him, should she even try?
     Snippet:
     “Jonathan?” Clary said. He was just getting to his feet and she
     barely had time to react before he was barreling into her with open
     arms. She dimly registered that his cheeks were wet and he was
     kissing her hair.
     “Thank you, thank you so much, little sister. I feel so… alive. You
     could have let me die and maybe I should have but you wanted me in
     your life. Thank you.”

***** A family once again *****
“I don’t hate you,” she said finally. “I hate Sebastian. I don’t know you.”
Jonathan’s eyes fluttered closed. “I dreamed of a green place once,” he
whispered. “A manor house and a little girl with red hair, and preparations for
a wedding. If there are other worlds, then maybe there is one where I was a
good brother and a good son.”
Maybe, Clary thought, and ached for that world for a moment, for her mother,
and for herself. She was aware of Luke standing by the dais, watching them;
aware that there were tears on Luke’s face. Jace, the Lightwoods, and Magnus
were standing well back, and Alec had his hand in Isabelle’s. All around them
lay the dead bodies of Endarkened warriors.
“I didn’t think you could dream,” said Clary, and she took a deep breath.
“Valentine filled your veins with poison, and then he raised you to hate; you
never had a choice. But the sword burned away all that. Maybe this is who you
really are.”
He took a ragged, impossible breath. “That would be a beautiful lie to
believe,” he said, and, incredibly, the ghost of a smile, bitter and sweet,
passed over his face. “The fire of Glorious burned away the demon’s blood. All
my life it has scorched my veins and cut at my heart like blades, and weighed
me down like lead—all my life, and I never knew it. I never knew the
difference. I’ve never felt so . . . light,”
 
Just then, just as Jonathan took what could be his last breath a blinding
vision came to Clary. Her head rattled from the inside out with the power of
it. A rune with high curving arcs and soft lines blared in her mind and
something told her to draw it on her brother. She whipped her stele out just as
his last exhale was leaving his lungs. As she completed it Jonathan took a
sharp breath and his eyes flew wide.
 
“Sister what have you done…” Sebastian said as he took a shuddering breath.
 
The angel, the angel Raziel drifted down on a cloud toward them. “I have been
summoned to demon realm by shadowhunters. What misdeeds are afoot here?”
 
Clary looked up at the angel in wonder. This was the second time she’d seen
Raziel and the experience wasn’t lessened the second time around.
 
“I don’t know what happened! I had a vision and I applied the rune and you
came . I’m sorry.” Clary wasn’t sure what to say. The pool of flaming blood
around Jonathan was widening.
 
“You summoned me with the rune of redemption, only a being with nearly pure
angel blood can use the rune.”
 
“Can you help my brother? Can you save him?” Clary asked shakily.
 
“I will say this, he  can  be saved. I’m sure you remember when I brought your
Jace back to life well, we could work something out akin to that. But! You must
never summon me again. Should you use this rune again or attempt to summon me I
will smite you with lightning.”
 
“It’s a deal,” Clary said, but Jonathan interrupted them.
 
“What if I don’t wish to be saved! I should die for what I have done!” He said
raspily. He had a quantity of blood pouring out of his mouth and his wound was
still on fire.
 
“The decision is in Clarissa’s hands.” The angel said frostily.
 
Clary looked down at her mother. The mother who had always wished that Jonathan
was born with angel blood and not demon blood. She could make her mother’s
deepest wish come true and save her brother at the same time. She could get to
know him, see if he was as changed as he claimed to be.
 
“Do it.” She commanded the angel.
 
The Angel hovered his hand over Jonathan’s chest and a beam of heavenly light
shone from his hand Jonathan’s body started to levitate off the ground and he
hung in the air there for a moment. It made Jonathan glow gold and slowly, his
body stopped burning and the dark mark where Heosphoros had punched through his
chest glowed the brightest. Just as soon as it had come it started ebbing away
and Jonathan drifted back down to the ground. The fire was completely put out
and the red blood that had seeped out of Jonathan’s body was gone. The tear in
his shirt mended itself as well.
 
“I have done as you wish. Jonathan Morgenstern now has the blood of the angels
within him, as was always supposed to be the case.” Raziel’s angel wings
fluttered and he shot into the sky leaving a trail of golden light.
 
“Jonathan?” Clary said. He was just getting to his feet and she barely had time
to react before he was barreling into her with open arms. She dimly registered
that his cheeks were wet and he was kissing her hair.
 
“Thank you, thank you so much, little sister. I feel so…  alive . You could
have let me die and maybe I should have but you wanted me in your life.  Thank
you. ”
 
It was a little awkward at first but she could see her mother crying tears of
joy and from behind her she dimly noticed Jace coming from behind her to hug
both Jonathan and Clary. He probably said what she should have. “I knew there
was a good brother inside of you somewhere,” Jace muttered as he squished us
into the hug and Clary felt her heart sing. They were really going to do this.
Her brother was whole again, he was  as he should have been  and they were
going to be a family.



***** I want that too *****
Chapter Summary
     Jace and Jonathan turn up the heat.
Clary was restless. She hadn’t been able to sleep a wink since they’d gotten
back and she felt like she was catching something. No doubt caused by being out
on patrol in the dark and the cold for three days in a row. In the wake of the
Endarkened’s destruction, small bands of demons had surfaced and were wreaking
havoc on the streets of New York. She had to be awake in 5 hours and it would
be nice if she didn’t wake up Jace with all her tossing and turning. She peeled
off the covers and tiptoed out of bed. She snuck into the kitchen and in the
dark stumbled into someone. She flicked the light on and stared back at her
brother.
 
“You scared me.” She said softly.
 
“Sorry. I can’t sleep.” Jonathan said shortly.
 
“Yeah me either,” Clary grumbled.
 
“I’m having nightmares.”
 
“What about?” Clary said, as she pulled a canister of tea from the cupboard and
poured some water from the tap.
 
“Just… everything I did before the angel saved me. God, Clary, I’m so sorry.”
He had turned to the fridge and was pulling out the milk.
 
“I know you’re sorry Jonathan. I know the Clave is still deciding what should
be done with you but once they’re done we should go somewhere, just Jace, you,
and me, like a vacation.” Clary said, as she slid her mug into the microwave
and turned it on.
 
“They might decide to lock me up in the Bone City forever, though,” Jonathan
said remorsefully as he took out a packet of powdered hot chocolate and stirred
it into his milk.
 
“I doubt that,” Clary said shortly. She knew her brother had committed
horrendous crimes against the Clave but an actual angel was the reason he’d
come back. There were people in the Clave that were thirsty for revenge and she
couldn’t blame them.
 
“It’s just going to be hard don’t you think? Proving that I’m not Sebastian
anymore and making people like me.”
 
She took her tea out of the microwave, and located the sugar, she spooned a
teaspoon into the tea and stirred thoughtfully. “Who are the top three people
you want to make amends to?”
 
“I don’t know, I want to make everyone forget that I was that person.”
 
“Well, I don’t think anyone is going to forget what happened Jonathan. But
maybe you could start with Maryse? You could write her a letter and explain how
sorry you are about Max. Nothing you say is going to make it completely heal
but she would be more understanding if she knew you truly felt remorseful. It’s
probably best to seek forgiveness not a loss of people’s senses.”
 
He put his cup in the microwave and looked at her, they were close, so close
that Clary could feel the heat coming off Jonathan’s body in waves. She looked
up at him, his eyes were so green, like the color of leaves in the spring. He
leaned in a little. She was so short he actually had to lean  down  in order to
look her in the eyes.
 
“Do you think I deserve forgiveness?” He questioned.
 
She flushed. “I don’t think I’m forgiving the same person that committed those
terrible crimes. You’re not Sebastian. Like I said,  I don’t know you . I know
you’re a good person, at least from what I’ve seen, in the last few days alone
you’ve saved my ass from demons at least five times.”
 
He smiled down at her where the cruel smirk was just days ago there was a
playful smile in its wake. “Actually it was six.” He licked his lips and
laughed. “If you want me to teach you a few things we can head to training room
tomorrow?”
 
Clary was looking at him as if she could see through him. He was warm with
kindness and she wanted to touch him. His hair was getting longish and his
white-blonde hair framed his face. She was sure her hair looked like a rat’s
nest. “Yeah, that sounds good.” But she wasn’t looking into his eyes when she
said it. She was looking at his lips. They were pink and supple, it looked like
he used chapstick regularly. She leaned in closer to him, infinitesimally. He
noticed though and she’d been hoping he wouldn’t notice her.
 
His eyes searched her face, she wondered if he was looking or a trace of doubt.
She hoped there wasn’t one because she really wanted him to kiss her. He leaned
in and hovered over her lips and she closed the gap. Their lips met and it was
a soft kiss, tentative and exploring. She knew she shouldn’t she knew this was
wrong on so many levels. Jace would probably slay her if he knew. She pulled
back just as used his tongue to swipe the line of her mouth, requesting
entrance. She denied him, took her tea and swept past him.
 
“Clary…” He said as she shot past him, darting into the night.
 
The next night after Clary had walked out on their makeout session (he didn’t
know if it could be called that because they’d kissed for barely a minute)
Jonathan was in the library reading from a dusty tome when Jace walked in.
 
“Have you seen Clary around?” Jace said, settling down in one of the old
leather couches.
 
“No, I haven’t.” Jonathan snapped, feeling a little annoyed. He didn’t want to
think about Clary right now. He couldn’t explain what had happened the previous
night. Maybe Heosphoros hadn’t burned  everything  evil out of him. He had no
other way to explain why he’d kissed his sister last night.
 
“Whoa, take it down a few notches,” Jace said putting his hands up.
 
“Sorry… I’m just not adjusting to this whole ‘ everyone hates me’  thing so
well.” Jonathan spat.
 
“Damn, relax. I don’t hate you.” Jace said with confidence.
 
Jonathan put his book down and closed it. “You don’t?”
 
“Nah, as soon as Clary summoned the Angel I knew you would be different, better
probably. As much as what I hate what you did to Max, I understand that the
demon blood had changed you and you’re a different person without it.” Jonathan
listened to Jace and got up from his place at the desk he was sitting at and
went to sit next to Jace.
 
“You have no idea how much I regret what I did to Max. God, I wish I could take
it back.” Jonathan sighed.
 
“I know you do, we all do,” Jace said solemnly.  
 
“There are so many things Sebastian did, that  I did,  that seem so awful and
offensive to me. It’s hard for me to align the fact that the same person in my
body did these horrible things. It just feels like it was ten lifetimes ago.”
 
Jace took Jonathan’s chin and made it so they were looking each other in the
eyes. They were almost matched for height, with Jonathan being just a little
taller. “For you, it  was  ten lifetimes ago because you’re not that guy
anymore. You’re not the guy who almost raped Clary,” Jonathan felt his heart
sink, “And you’re definitely not the guy who killed Max and that’s why Clary
and I are trying so hard to get the Clave to allow you to stay for the
indefinite future.” The whole time Jace was talking Jonathan’s eyes kept
flitting down to his lips. They were a little chapped and looked like he’d been
biting them. Jonathan sucked in a breath.
 
“Jace, I just… I don’t know what to do. It seems so unfair that people would
have to live with me. Clary said I should write Maryse a letter and tell her
how sorry I am for what happened to Max and I mean, I will, but... what good
will it do?”
 
Jace cupped Jonathan’s cheek and said, “If she knows that you’re sorry it might
be easier for her to live with the Clave’s decision.”
 
“Does that mean they’re not going to throw me in the Bone City for the rest of
my life?” Jonathan asked.
 
“Probably not, not with the testimony Clary and I have given,” Jace said
slowly. “It’s a big deal when the Angel blesses you with angel blood,” Jace
said, brushing his thumb over Jonathan’s cheek.
 
“Do you think I deserve it?” Jonathan whispered.
 
“Yes,” and then Jace leaned in and kissed his adoptive brother. Jonathan didn’t
waste time waiting to deepen the kiss, he let his tongue push into Jace’s mouth
and they were ravenous for each other. Jonathan’s tongue battled Jace’s and
their teeth gnashed at each other. Jonathan pulled Jace into his lap and
continued the assault on his brother’s lips. Jace was taking rapid breaths in
through his nose but soon it wouldn’t be enough, they would have to separate
for air. Their tongues twined once more and they separated, Jonathan leaned
back on the couch, drawing in deep lungfuls of air.
 
Jonathan had the decency to blush. He tangled his fingers in Jace’s curly hair.
“I’d ask if we could do more but since we  are  in the middle of the library
I’ll be good,” Jonathan said in Jace’s ear.
 
They burst into laughter and Jace shimmied off Jonathan’s lap and Jonathan let
his grip on Jace’s hair go. Someone cleared their throat from the doorway.
Jonathan and Jace’s heads snapped up and they were looking at a teary eyed
Clary. She made a rude hand gesture at them both and stormed out. The sounds of
her tears filled the Institute.
 
“Damn it, we’re in trouble,” Jonathan said.
 
“I’ve gotta go after her.” And Jace took off after her, leaving Jonathan to
wonder.


Jace tore down the hallway and followed after her. Her sobs were getting louder
and louder. Finally, she stopped and he almost ran into her. “I’m sorry!” He
burst out.
 
“No, you don’t u-understand.” She sobbed.
 
“What don’t I understand?” He said as calmly as he could but his heart was
racing in his chest.
 
“I-I want…” Her head bowed down though and she looked at the ground. Jace
couldn’t understand what was going on. Was Clary hiding something from him?
 
“What do you want baby?” Jace asked his girlfriend.
 
She looked up at him, “You have to promise not to get mad!” Clary burst out.
 
“Ok, ok. I won’t get mad.” All of this was making him incredibly nervous.
 
“I k-kissed Jonathan last night! And I want the three of us to be together,
like together, together, not like a family.” Her sobs kept getting louder and
Jace slipped his arms around her waist and held her tight to him.
 
“I want that too baby, I want that too.”
