Part 5! I'm having loads of fun writing this, guys, and I'm so glad people are actually liking it. Remember to R&R!

"Guys! Guys, I'm back, I'm okay!"

Alec, Isabelle, and Jace glanced at the doorway where Clary stood with a tiny bundle in her arms. Alec raised an inquisitive eyebrow. "What?"

Clary's smile faded. "I'm back. Wasn't I gone for long?"

"Clary, you left to go to the bathroom like ten minutes ago." Isabelle tilted her head curiously as she eyed the bundle in Clary's arms. "What's that?"

"Wait a minute!" Clary cried. "You mean I got knocked out by my psycho demon brother and dragged into another freaking dimension, and none of you even noticed?"

Jace froze. "Wait, what? Sebastian was here?"

"Yes! He kidnapped me!"

Jace was up in a flash. "Where is he? I'll kill him—"

"Shut up and sit down, Angel Boy," Clary snapped. "He's not here. I managed to escape, no thanks to any of you."

"We're glad you're back and everything, Clary, but I believe we have yet to address the elephant in the room." Alec gestured at the bundle. "What is that?"

Clary brushed the corner of the wool blanket away from Lilith's face. "Well, it's kind of a long story…"

"You were gone for ten minutes. It can't be that long."

Clary glared at him. "Fine. Everyone, say hello to my niece."

The room was quiet enough to hear a pin drop.

"Please tell me you're joking," Jace said. "Please tell me that you are not actually holding the spawn of Sebastian-freaking-Morgenstern in your arms."

Clary glanced down at Lilith, who was making small whimpering noises as she struggled to get comfortable in her aunt's arms. Jocelyn had said that when Sebastian was a baby, he hadn't showed any real emotion. But this wasn't the case with Lilith. She smiled and laughed and cried like any normal baby. Even her father-given black eyes were alive and snapping with vibrant emotion.

"She doesn't seem like she's got demon blood," Clary said quietly. "I mean, just look at her. She's a normal baby."

Isabelle got up and came over to inspect the child. She narrowed her eyes. "She looks just like him."

"But she's not like him," Clary said. "My mother said that Sebastian didn't show any emotions when he was a baby. He didn't even cry. Lilith's not like that."

"By the Angel," Isabelle gave her an incredulous look. "He named her after a demon?"

"This is Sebastian we're talking about," Alec said dryly.

"What are you gonna do with her?" Isabelle questioned. "The Clave-"

"We are sure as hell not telling the Clave, or anyone outside this room, for that matter," Clary interrupted. "Except for Simon. And Magnus. And maybe my mom-"

"Clary," Alec said. "We can't keep this thing here."

"She's not a thing," Clary argued. "She's more Shadowhunter than demon. And besides, Sebastian turned out bad because Valentine raised him. Maybe if we were to take this little one in, she could grow up to be good."

"Wishful thinking," Jace shook his head. "But no. Clary, for all we know, this isn't even Sebastian's kid. It could be a demon in disguise."

"Then explain how I got her past the Institute's wards."

The hall fell silent. Alec spoke up, "Y'know, she's got a point."

Jace sniffed disdainfully. "Or she could be a spy."

"Jace, she's two months old."

"She's part demon. You don't know what she's capable of."

Clary rolled her eyes. "Well, I'm taking her home to my mother. She'll know what to do."

"Over my dead body."

"Oh for the love of-" Clary whirled around to snarl at Sebastian, who'd appeared in the doorway with a legion of Endarkened behind him. "Did you seriously follow me here all the way from your crappy knock-off demon Gard?"

Sebastian bared his teeth. "My Gard is not a knock-off. My Gard is better than your Gard."

Jace piped up, "Yeah, well my Gard is bigger than your Gard."

"I think most women would agree that my Gard is in fact the biggest and bestest Gard of them all."

"Okay," Alec said cautiously. "I think we've gotten off topic here."

"Silence, peasant," Sebastian snapped, pointing Phaesphoros at him.

Jace came to Alec's defense. "Hey! Nobody calls my parabatai a peasant!"

Alec stood up a little taller.

"Except me!"

Alec deflated.

Sebastian appeared unimpressed. He casually flicked the tip of his blade. "Keep them away from me," he drawled lazily. "And fetch me my sister and my daughter."

"You're not gonna touch Clary!" Jace snarled, leaping up to stand in front of her. "You can take your demon kid back, though. Clary, give it to him."

Clary's eyes widened. "JACE."

He huffed. "Fine. You can't have either of them." He muttered something inaudible under his breath.

Sebastian snapped at his Dark warriors, "Quickly! Before the entire Clave comes running, you fools! We can't be here for long!"

The Endarkened surged forward. Jace faced the oncoming Shadowhunters fearlessly, until he realized that there were no weapons strapped to his belt. He gulped. "Well, shit."

"We're totally unarmed," Alec backed away from the charging horde.

"Plan B, then," Clary said.

Isabelle turned to her. "What's Plan B?"

Clary clutched a wailing Lilith to her chest and turned on her heel, calling over her shoulder, "FUCKING RUN!"
