Knowing Sebastian
"Clary!" Isabelle yelped, and darted after her, but Clary was already halfway down the hall. She saw, with the half of her mind that wasn't concentrating on dodging Isabelle, that the house was built like Amatis's, tall and thin, but considerably larger and more richly decorated. The hallway opened into a room with high windows that looked out over a wide canal. White boats plied the water, their sails drifting by like dandelion clocks tossed on the wind. A dark-haired boy sat on a couch by one of the windows, apparently reading a book.
"Sebastian!" Isabelle called. "Don't let her go upstairs!"
The boy looked up, startled—and a moment later was in front of Clary, blocking her path to the stairs. Clary skidded to a halt—she'd never seen anyone move that fast before, except Jace. The boy wasn't even out of breath; in fact, he was smiling at her.
"So this is the famous Clary." His smile lit up his face, and Clary felt her breath.
"So it would seem" she replied. Then let out a sharp laugh and threw her arms around him. He laughed in reply "I missed you" they said at the same time.
In the distance background, they heard a gasp. "You two know each other" Isabelle blurted out. "But… but… he's a shadowhunter"
"Yeah, I know, but…" Clary tried explaining.
"Hey, let's just say we know each other pretty well" said Sebastian.
"But… that still doesn't make any sense" said Isabelle.
Clary just shook her head, "Does anything? Please let me see Jace. Please."
Isabelle had a pained look on her face, "Fine, Clary," she said, with an unusual—for Isabelle—amount of anger in her voice. "Go ahead and do whatever you want, regardless of who it hurts. You always do anyway, don't you?"
