Kind of a short one this time. No Lilith in this part, just a little Clary and Sebastian bantering. I wasn't feeling too inspired to work on this today, but I felt bad for keeping you guys waiting and decided to post something anyways.

Lily will be back next chapter, I promise!

"Hello, Clarissa."

Clary sat up on the bed with fear in her eyes. Sebastian shut the door and locked it, not bothering to hide the gleeful grin on his face. He started towards her, painfully slowly.

"Stay away from me, you freak!" Clary started kicking her legs, scooting over to the other side of the bed as her brother grew nearer.

"Calm down, Clarissa." Sebastian tutted. "I'm not going to hurt you."

"Sorry if I have a hard time believing that," Clary said monotonously.

"Clary, Clary, Clary," he sighed. "Where do you get these ideas? Why would I ever want to hurt my baby sister?"

"Because you've got some sick, incestous obsession with me, freakshow."

Sebastian gazed down at Clary, tied up and vulnerable on his bed, and frowned. "I'll untie you," he said. "But you have to promise not to run away."

Clary laughed. "The day I stop fighting you will be the day that the Lions win the Superbowl."

Her brother tilted his head. "What?"

Clary rolled her eyes. "Of course you wouldn't know. Do you not know anything about modern society?"

"Not really. Did you forget? I grew up in a rural manor in Idris, Clarissa." He paused. "What is this 'Superbowl' thing, anyways?"

"Football championship."

"Football?" Sebastian rubbed his chin. "Ah. That mundane sport with the black-and-white ball, right?"

"Not in America, buddy. That's called soccer."

"And football is something else here?"

"Yeah, it's-" Clary's eyes narrowed. "Are you really making small talk with me right now?"

Sebastian shrugged. "I suppose I am."

"Well stop it, it's weird."

"Why is it weird for siblings to talk with each other?" Sebastian slid onto the bed and put his arms behind his head in a picture of leisure. "I just want to get to know my sister a little better."

"Well that's just a damn shame, because I don't want to get to know you."

"Why not?"

Clary glared at him. "Why? I'll tell you why." She hissed, "You're a murderer. A demon thing."

Sebastian placed his hand over his heart. "You wound me, dear sister." He crept towards her on all fours, like a predator stalking its prey.

Clary edged away from him. "I'll wound you for reals if you don't get away from me, you fucking psycho!"

"Come here, little sister," Sebastian purred, wrapping one arm around her middle. "Let's snuggle."

"Ew, ew, ew, stop touching me! You're gonna give me diseases!" Clary gasped. "Demon pox. You're gonna give me demon pox! Oh Raziel, help me!"

Sebastian scowled. "I'm not going to give you demon pox, Clarissa."

"Oh Raziel, Raziel, please help me!" Clary wailed. "Send a bolt of lightning into Edom and smite this foul beast!"

"Clarissa-"

"Quickly, before he infects me!"

Sebastian huffed and pushed her away. "I can't give you pox. I'm not full demon."

Clary smirked. "Demon pox, oh demon pox-"

"Clary, I swear, if you start singing that-"

"Just how is it acquired? One must go down to the bad part of town-"

"Your boyfriend must be a Herondale-"

"-until one is very tired!"

"Shut up or I'll duct tape your mouth."

Clary stopped singing, but the silly grin never left her face. Sebastian growled at her. "You and Lilith have both driven me past the point of exhaustion. Goodnight, sister. I'll see you in the morning." He pushed off of the bed and skulked out of the room, slamming the door behind him.
