What to buy for the Shadowhunter who has everything

Part 5.

She would stand by him. She loved her brother, then.

"That's good to know." said Magnus.

He had known Isabelle Lightwood was beautiful, and had thought she seemed strong, and funny---had known that she was someone he had not mind having a drink with or having at a party. He had not known that there were depths of loyalty and love in her.

He was not adept at reading Shadowhunter hearts, behind their smooth angelically arrogant facades. He thought that might be why Alec surprised him so much, had wrong-footed him so that Magnus had stumbled into feelings he had not planned to have. Alec had no facade at all.

Isabelle nooded, as if she understood what Magnus was telling her. "I thought---it seemed important to tell someone that, on his birthday," she said. "I can't tell anyone else, even though I would. It's not like my parents or the Clave would listen to me." Isabelle curled her lips as she spoke of both her parents and the Clave. Magnus was liking her more and more. "He can't tell anyone. And you won't tell anyone, right?"

"It's not my secret to tell." said Magnus.

He might not enjoy sneaking around, but he would not tell anybody's secret. Least of all would he risk causing Alec pain or fear.

"You really like him, right?' Isabelle said. "My brother?"

"Oh, did you mean Alec?" Magnus retorted. "I thought you meant my cat."

Isabelle laughed and kicked at one of Magnus's cabinet doors with one spike heel, careless and radiant. "Come on, though," she said. "You do."

"Are we going to talk about boys?" Magnus inquired. "I didn't realize and I am honestly not prepared. Can't you come over another time, when I'm in my jammies? We could do homemade facials and braid each other's hair, and then and only then will I tell you that I think your brother is totally dreamy."

Isabelle looked pleased, if a little mystified. "Most people go for Jace. Or me," she added blithely.

Alec had said as much to Magnus once, seeming stunned that Magnus might hope to see him instead of Jace.

Magnys was not planned on talking about why he preferred Alec. The heart had its reasons, and they were seldom all that reasonable. You might as well asked why Clary hadn't created a hilarious love triangle by getting a crush on Alec, since he was---in Magnus's admittedly biased opinion---extremely handsome, and had been consistently sullen in her direction, which some girls liked. You liked the people you liked.

For all that, Magnus had many reasons. Nephilim were guarded, Nephilim were arrogant, Nephilim were to be avoided. Even the Shadowhunters Magnus had met and liked had been, everyone, a trouble sundae with dark secret cherries on top.

Alec was not like any Shadowhunters Magnus had met before.

"May I see your whip?" asked Magnus.

Isabelle blinked, but to do her justice, she did not demur. She unlooped the electrum whip and tangled its silvery-gold length around her hands for a moment, like a child playing cat's cradle.

Magnus took the whip carefully, laid across his palms like a snake, and he carried it to his closet door, which he opened. He drew out a special potion, one that he had payed an exorbitant price for and that he had been saving for something special. Shadowhunters had their runes to protect them. Warlocks had magic. Magnus had always liked his magic better than theirs. Only a Shadowhunter could bear runes, but he could give magic to anyone. He tipped the potion---faerie dust and blood taken in one of the old rituals, hermatite and hellebore and more besides---onto the whip.

In the last extremity this weapon will not fail you; in the darkest hour this weapon will bring your enemy low.

Magnus carried the whip back to Isabelle when he was done.

"What did you do to it?" Isabelle asked.

"I gave it a little extra kick," said Magnus.

Isabelle regarded him with narrow eyes. "And why would you do that?"

"Why did you come to tell me that you knew about me and Alec?" said Magnus. "It's his birthday. That means the people who care about him want to give him what he wishes for most. In your case, acceptance. In mine, I know that the most important thing to him in this world is that you be safe."

Isabelle nodded, and their eyes met. Magnus had said far too much, and he worried that Isabelle could see more.

She launched herself off the counter, toward Magnus's small alabaster-topped coffee table, and scrawled on his notepad. "Here's my number"

"May I ask why you're giving it to me?"

"Well, wow, Magnus. I knew you were hundreds of years old and all, but I hoped you were keeping up with modern technology." Isabelle held out her phone to illustrate her point, and waggled it about. "So that you can call me, text me. If you ever need Shadowhunter help."

"Me need Shadowhunter help?" Magnus inquired, incredulous. "Over the---you're right, hundreds of years---let me tell you that I've found it almost invariably the other way around. I presume you'll be wanting my number in return, and I'm also prepared to bet, based on nothing more than a passing acquaintance with your circle of friends that you're going to get into trouble and need my expert magical assistance rather a lot."

"Yeah, maybe," said Isabelle with a rakish grin. "I've been known to be a troublemaker. But I didn't give you my number because I want magical help, and okay, I understand that the High Warlock of Brooklyn probably doesn't need an assist from a bunch of underage Nephilim. I was thinking that, if you're going to be important to my brother, we should be able to get in touch. And I was thinking that you might want to have it if---if you need to contact me about Alec. Or if I need to contact you."

Magnus understood what the girl meant. His number was easy to get---the Institute had it---but in giving him her own, Isabelle was offering free exchange of information about Alec's safety. The Nephilim led dangerous lives, chasing after demons, stalking the Downworld for lawbreakers, their rune-Marked, angel-swift bodies the last line of defense for the mundane world. The second time Magnus had ever seen Alec, he had been dying of demon poison.

Alec could die at any time, in any of the battles to come. Isabelle would be the only Shadowhunter who knew for sure that there was anything between Magnus and Alec. She would be the only one who knew that if Alec died, Magnus would be someone who needed to be told

"All right," he said slowly. "Thank you, Isabelle."

Isabelle winked. "No need to thank me. I'll be driving you mad before long."

"I'll be expecting it," said Magnus as she clattered out on her high, weaponized heels. He admired anyone who made beauty and utility work together.

"By the way, that demon is dripping slime all over your floor," said Isabelle, poking her head back around the door.

"Hi," said Elyaas, and he waved a tentacle at her.

Isabelle regarded him with disdain, then raised an eyebrow in Magnus's direction. "Just thought I'd point it out," she said, and closed the door.
