Fire to Water

Two weeks earlier

A/n: I changed the timing bc it didn't make sense with the rest of it and I can't make them that oblivious for that long, but nothing else is different.

"Kit! Kitkitkitkit!"

"Morning, Mina. Morning Jem."

The morning light streamed in through the (admittedly broken) glass doors, falling in patterns on the tiled floor. Kit leaned over his sister for a cup, and she cackled in delight, fisting  her hands in his shirt. "Kit, up! Up up up! Play bad cat!"

Jem gave Kit the look over his cup of tea. For a man who was generally a complete marshmallow, he was, at times, utterly terrifying. This was one of those times.

Kit hated to admit it, but the look was warranted. Playing bad cat with Mina was the reason the door was no longer a single pane of glass, and where the large dent above the stove came from.

"Sorry, Jem."

Jem went back to his tea and calmly moved Mina's cup out of the elbow danger zone. "You already promised to repair it," he said. "I'll just teach you the closed rune today."

Kit, who had been anticipating a day of picking up all the little shards that had somehow wedged themselves into the smallest crevices of the floor, perked up. "There's a closed rune?" And yep, he was already picturing it as reparo from Harry Potter.

"There is not a closed rune," Tessa said, walking into the room. 

Jem hid his smirk behind his teacup.

"You were going to prank me?"

"It's a valuable lesson on how healing runes only work on Shadowhunters, and not inanimate objects."

"You are a jerk," Kit said.

"Juk," Mina echoed, "juk juk juk juk."

"What about the open rune?" Kit continued. "You don't put that on people."

"That's an exception."

"A singular exception. There's no closed rune."

"That's just disappointing. So it's not, like, reparo! And boom!" He made a motion as if he were pointing a wand. 

"Read that book," Tessa said. "But no."

"Saw that movie."

"I need to speak with you, though," Tessa said, "honestly. And not in front of Mina."

Kit instantly put his cup down and followed her out of the room.

Oh no. Oh no oh no. Was it about the Blackthorns? Had someone (else) died? Had something happened to—

Nope. Not going there, no. 

Not now, brain.

"What's up?" He knew it was probably really, Kit, pick up your socks  or where did you last see the cat or where did Mina's whatever go, but he almost automatically prepared for the worst. It was a habit he hadn't been able to shake from his dad (his real dad, not his Jem-dad, not that Jem was his dad).

"Clary is... missing." She said.

"Can't someone track her?" Kit asked. This was not either of the things he had expected. He remembered Clary, vaguely, as sort of a small, happy woman made mostly of bright red hair. She was Jace's girlfriend— no, his wife. Kit had been technically invited to the wedding, but the Blackthorns had been as well, and he would rather not see them, specifically one of them, ever again.

"It's not working. And since you're related to her, it might be nice if you could help."

"I'll help," Kit said. "Of course."
