In the end, Clary was able to convince Jonathan to turn. He only had one qualm about it, however -

"Let me get better,", he told her, the two of them on his bed, as always. "Let me get… Stable. I don't want to be a burden to you."

Clary accepted it, and as such, lived her best - she changed from normal schooling to homeschooling, claiming to her mother she wanted a better portfolio for art school, went occasionally with Simon and Jonathan to Pandemonium, and once in a while Izzy appeared with a box full of blood and tales of times gone by.

"Yeah, and then me and Alec were in London, and Jace was a bell bottom at the time, looking air-tight, flirting with this bird, but she was all 'fella, I'm not fried enough for this so go chase yourself', so Alec had to feed him a line about Raphael looking for us to see if he would quit it,", Izzy said, over mugs of coffee (for the humans) and blood (for the vampires), and Clary and Jonathan looked at each other, as Simon seemed absolutely in awe.

"Is that how we're going to sound in a thousand years?", he asked, and Clary shrugged.

"At least you understood what she said,", Clary replied, taking a smile off him. "I need a dictionary. Or a drink."

"You're underage."

"I'm going to be sixteen forever, Sebastian. I think 'underage' here is relative.", she stuck her tongue out, and Jonathan, with a deep fake sigh, settled for messing her hair.

Jonathan asked to be turned in his twentieth birthday, and Clary obliged. His blood was thick against her tongue, and she offered him her wrist to drink; his frenzy was something she had never imagined, and it was hard to contain herself when Izzy watched, by her side a ice box filled with blood bags - "for the both of you,", she said, when Clary asked why, and now she can understand; Clary can feel herself being sucked dry, can feel the thirst on the back of her throat, a bottomless pit in her stomach.

She had to pull off her wrist from his mouth, Jonathan's eyes wild and unusual. He stayed quiet, and Clary cannot remember how she was while transforming to compare. Clary rose up and joined Izzy, the two of them staying quiet.

"He's doing well,", Izzy says, in the end, offering her a blood bag that she accepts. "I remember when it was Alec's turn, he couldn't stop moaning."

"It hurts?", Clary asked, and Izzy looked at her, bewildered.

"Of course it hurts, you're growing your teeth, slowing your heart, a bunch of things. Don't you remember?", Izzy asked, and Clary slowly sipped at her bag of blood. She didn't, in fact. All she remembered were flashes, but no pain was seared in her memory. When Clary shook her head, Izzy laughed. "Hey, maybe it's a special thing for your family. Not feeling the pain, you know? Maybe you two were destined to be a vampire."

Clary hardly thought so - she had heard the whispered conversations that her mother had with the nurses, and their father had been a fan of corporal punishment, her mind remembering how Jonathan had been that first few months. If Jonathan wasn't reacting, it wasn't because he didn't feel the pain; it was because he was trained to stay quiet. Clary was half-regretting turning her brother already.

"Who knows?", Clary said, in the end, deciding that Jonathan could tell it all if he wanted later. They'd have all eternity, after all.

Jonathan came back to his senses hours later, and Izzy didn't even speak to him, just handing Jonathan blood bag after bloodbag. She didn't remember that.

"I don't think I'm a normal vampire,", Clary said, sitting on the floor, and Izzy laughed.

"Doll, I think we all knew that already.", Izzy clapped, and Jonathan's eyes lost their wild quality. "Welcome, Jonathan, to your new eternal life. Anything you want to say?"

"Yeah, I hope the pain was worth it,", Jonathan replied, and Izzy laughed.

"Oh, it will be. Now, I'll leave you two alone. I'll be returning in twenty minutes, so be done with whatever you two want to do before that, alright?"

Clary blushed, but Jonathan laughed, putting a hand on her shoulders. Izzy, with a satisfied smirk, took her leave, closing the door behind her, and as soon as she did that, Jonathan kissed her passionately.

When they separated, he smiled shyly, almost, fangs showing.

"Remember we have twenty minutes,", she told him, but Jonathan's grin only grew.

"I thought we had eternity."

"We do,", Clary replied, and Jonathan kissed her again.

I know I said "two final chapters", but the "Jonathan doesn't turn" option was too sad.
