"Yes. " Will looked back at him, and the strain in his expression relaxed slightly. "If we might return to discussing your plan, James. Its a good one, save one thing. " He leaned forward. "If she is meant to be affianced to you, Tessa Will need a ring. "
"I had thought of that," said Jem, startling Tessa, who had imagined he had come up with this Ascendant idea on the spot. He slipped his hand into his waistcoat pocket and drew out a silver ring, which he held out to Tessa on his palm. It was not unlike the silver ring Will often wore, though where Will s had a design of birds in flight, this one had a careful etching of the crenel ations of a castle tower around it. "The Carstairs family ring," he said.
"If you would . . . "
She took it from him and slipped it onto her left ring finger, where it seemed to magical y fit itself. She felt as if she ought to say something like Its lovely, or Thank you, but of course this wasnt a proposal, or even a gift.
It was simply an acting prop. "Charlotte doesnt wear a wedding ring," she said. "I hadnt realized Shadowhunters did. "
"We dont," said Will. "It is customary to give a girl your family ring when you become engaged, but the actual wedding ceremony involves exchanging runes instead of rings. One on the arm, and one over the heart. "
"Set me as a seal upon thine heart, as a seal upon thine arm: for love is strong as death; jealousy is cruel as the grave," said Jem. "Song of Solomon. "
"Jealousy is cruel as the grave?" Tessa raised her eyebrows. "Thats not . . . very romantic. "
"The coals thereof are coals of fire, which hath a most vehement flame,"
said Will, quirking his eyebrows up. "I always thought females found the idea of jealousy romantic. Men, fighting over you . . . "
"Well,
there arent any graves in mundane wedding ceremonies," said Tessa. "Though your ability to quote the Bible is impressive. Better than my aunt Harriets. "
"Did you hear that, James? She just compared us to her aunt Harriet. "
Jem, as always, was unruffled. "We must be on familiar terms with all religious texts," he said. "To us they are instruction manuals. "
"So you memorize them all in school?" She realized she had seen neither Will nor Jem at their studies since she had been at the Institute. "Or rather, when you are tutored?"
"Yes, though Charlottes rather fal en off in tutoring us lately, as you might imagine," said Will. "One either has a tutor or one is schooled in Idris-that is, until you attain your majority at eighteen. Which Will be soon, thankful y, for the both of us. "
"Which one of you is older?"
"Jem," said Will, and "I am," said Jem, at the same time. They laughed in unison as well, and Will added, "Only by three months, though. "
"I knew youd feel compel ed to point that out," said Jem with a grin.
Tessa looked from one of them to the other. There could not be two boys who looked more different, or who had more different dispositions. And yet.
"Is that what it means to be parabatai?" she said. "Finishing each others sentences and the like? Because there isnt much on it in the Codex. "
Will and Jem looked at each other. Will shrugged first, casual y. "It is rather difficult to explain," he said loftily. "If you havent experienced it-"
"I meant," Tessa said, "you cannot-I dont know-read each others minds, or the like?"
Jem made a spluttering noise. Will s lambent blue eyes widened. "Read each others minds? Horrors, no. "
"Then, whats the point? You swear to guard each other, I understand that, but arent all Shadowhunters meant to do that for each other?"
"Its more than that," said Jem, who had stopped spluttering and spoke somberly. "The idea of parabatai comes from an old tale, the story of Jonathan and David. And it came to pass . . . that the soul of Jonathan was knit with the soul of David, and Jonathan loved him as his own soul. . . . Then Jonathan and David made a covenant, because he loved him as his own soul. They were two warriors, and their souls were knit together by Heaven, and out of that Jonathan Shadowhunter took the idea of parabatai, and encoded the ceremony into the Law. "
"But it doesnt just have to be two men. It can be a man and a woman, or two women?"
"Of course. " Jem nodded. "You have only eighteen years to find and choose a parabatai. Once you are older than that, the ritual is no longer open to you. And it is not merely a matter of promising to guard each other. You must stand before the Council and swear to lay down your life for your parabatai. To go where they go, to be buried where they are buried. If there were an arrow speeding toward Will, I would be bound by oath to step in front of it. "
"Handy, that," said Will.
"And he, of course, is bound to do the same for me," said Jem. "Whatever he may say to the contrary, Will does not break oaths, or the Law. " He looked hard at Will, who smiled faintly and stared out the window.
"Goodness," said Tessa. "Thats all very touching, but I dont see exactly how it confers any advantages. "
"Not everyone has a parabatai," said Jem. "Very few of us, actual y, find one in the all otted time. But those who do can draw on the strength of their parabatai in battle. A rune put on you by your parabatai is always more potent than one you put on yourself, or one put on by another. And there are some runes we can utilize that no other Shadowhunter can, because they draw on our doubled power. "
"But what if you decide that you dont want to be parabatai anymore?"
Tessa asked curiously. "Can the ritual be broken?"
"Dear God, woman," said Will. "Are there any questions you dont want to know the answer to?"
"I dont see the harm in tell ing her. " Jems hands were folded atop his cane. "The more she knows, the better she Will be able to pretend she plans to Ascend. " He turned to Tessa. "The ritual cannot be broken save in a few situations. If one of us were to become a Downworlder or a mundane, then the binding is cut. And of course, if one of us were to die, the other would be free. But not to choose another parabatai. A single Shadowhunter cannot take part in the ritual more than once. "
"It is like being married, isnt it," said Tessa placidly, "in the Catholic church. Like Henry the Eighth; he had to create a new religion just so he could escape from his vows. "
"Til death do us part," said Will, his gaze still fixed on the countryside speeding past outside the window.
"Well, Will wont need to create a new religion just to be rid of me," said Jem. "Hel be free soon enough. "
Will looked over sharply, but it was Tessa who spoke. "Dont say that," she admonished Jem. "A cure could still be found. I dont see any reason to abandon all hope. "
She almost shrank back at the look Will bent on her: blue, blazing, and furious. Jem seemed not to notice as he replied, calmly and unaffectedly. "I havent abandoned hope," he said. "I just hope for different things than you do, Tessa Gray. "
Hours went by after that, hours during which Tessa nodded off, her head propped against her hand, the dull sound of the trains wheels winding its way into her dreams. She woke at last with Jem shaking her gently by the shoulders, the train whistle blowing, and the guard shouting out the name of York station. In a flurry of bags and hats and porters they descended to the platform. It was nowhere near as crowded as Kings Cross, and covered by a far more impressive arched glass and iron roof, through which could be glimpsed the gray-black sky.
