2 weeks later…

Isabelle was nervous, she had something to tell Simon and she wasn't sure how he was going to react; she hadn't even thought this was possible.

She heard him get out of the shower and she quickly grabbed a book, pretending to read. Simon came into the room completely dressed. Isabelle was still surprised by his vampire speed. He raises an eyebrow at her staring and then glances down at her book then back to her face, "you know the book is upside down right?"

"Simon I have to tell you something."

Simon looks into her serious face and sits down on the edge of the couch, "Is something wrong?"

"Impregnant…" she said really quickly trying to get it over with.

Now Simon, who with his vamp hearing heard the two words perfectly, stared at her incredulously.

"How is this even possible?" he asked.

Isabelle looked at her hands ashamed, "I-I don't know."

Simon runs his hands down his face and sighs, he looks at her sitting quietly in her chair and walks over to her, "Are you okay? How do you feel about this?"

"I don't know, I'm happy yet slightly freaked out, there is a baby shadowhunter growing inside of me."

"Well, the baby will also be a vampire; it takes two you know."

Isabelle blushes and swats at his arm playfully, "I'm fully aware, Simon Lewis."

Simon's stops and thinks for a minute before a grin breaks out on his face.

"What?" Isabelle asks.

"Just imagine what your brother is going to do when he finds out." Isabelle laughs and Simon joins in.

"We are going to have to start picking out names soon."

"Yeah, and we are going to have to tell your family."

"Oh God, we'll have to restrain Alec and Jace." Isabelle laughs again.

"Yeah haha, very funny; it's not your undead life on the line."

"We'll tell them after dinner," Isabelle smirks, "I'm cooking tonight."

"Oh my, someone save us." She swats at his arm again as she gets up and leaves.

…

"Thanks for dinner Iz, it was surprisingly delicious." Alec says.

Isabelle smile at Alec, "Thanks bro."

Then she looks to Simon and he nods.

"Alec, Clary, Mom, Jace… We have something to tell you."

"Isabelle's…"

"Well I'm sort of pregnant…"

"You're what!" Alec exclaims.
