A/N I just want to say thanks to everyone who favorite/followed this story and of course to my awesome reviewers and readers!

Six O'clock found Alec pacing the living room for in anticipation of his sister's arrival. He had the picture Catarina gave them in one hand and his small cellphone in the other. Briefly, he had considered calling her to cancel the meeting but in the end he knew he needed to tell her. She was his sister, he loved her and would be devastated if she ever kept something so important from him so he couldn't keep this from her. He could only hope she would take the news well and agree not to tell on him. Magnus wanted to tell Maryse and Robert but Alec was still convinced this was a bad idea. They'd not be one bit happy about it and if the Clave found out Alec didn't know what they'd do.

"Alec?" Isabelle asked. He looked up in surprise. He'd been so absorbed in his thoughts she'd slipped in unnoticed.

"Hey." He said, hiding the photo in his back pocket.

"So what's up?" She questioned, taking a seat on the couch. Alec sat down on the coffee table across from her and took a long, shaky breath.

"You're going to be a little shocked Iz. You may not even believe me, but I assure you that what I'm about to say is the truth. Okay?" He started. Isabelle nodded, eyes wide, and he continued. "A few months ago Magnus was helping a friend with an experimental potion. They though it failed but it didn't and it led to a rather unexpected side effect. I'm pregnant Isabelle."

"What?"

"I'm having a baby." He pulled the picture out of his pocket and handed it to her as if to validate what he was saying. His sister merely stared it in shock for at least two full minutes before saying.

"How?"

"Like I said they were working on an experiment. The point was to find a way to make warlocks fertile. Testing showed that it didn't work but evidently it did."

"You're seriously going to have a baby?"

"Yeah."

"Oh my God, I'm going to be an Aunt!"

"Yeah."

"Mom and Dad are going to flip!"

"Yeah. That's why we aren't telling them."

"Alec you can't hide a baby from them." Isabelle said practically.

"Not forever. But I can hide a pregnancy for a few months until I figure out what to say to them." He countered. She nodded at this, then looked away, thinking.

"Magnus knows?" She asked. Alec nodded. "That's why he asked you to move in." It was a statement not a question, but Alec confirmed it with a nod anyway. "How long have you known?"

"I found out yesterday. We got this," He tapped the photo. "A few hours ago."

"When is the baby due?" Isabelle questioned.

"Well it's the middle of January now and I'm like two months pregnant so…" He quickly did the math inside his head. "The middle of July."

"Wow. This is all so…"

"Crazy?"

"Yeah."

"I know."

"So, are you okay with all of this Alec?" His sister asked, handing back the picture.

"I was really freaked out at first, but once I calmed down and thought about it, everything started seeming okay." Alec admitted.

"How's Magnus taking all of this? Come to think of it where is he?"

"He wanted to give us some privacy and he realized we had no food so he's at the store. He's doing okay with it, better than me. I think I hurt him though."

"How so?"

"When I found out, I panicked. I thought he wouldn't want the baby and that I'd end up alone. I was imagining the worst and I told him what that was. I basically accused him of being a jerk and saying he'd leave us on the streets." Alec said, his face was filled with sadness and regret. Isabelle felt a pang of sympathy for him mixed with the giddiness that filled her when she saw that on the word us, her brother dropped a hand to the part of his abdomen where his baby would be.

"Oh I'm sure he understands that you didn't mean that!" She exclaimed. He must have been so terrified to find out he was having a baby. To her at least, it seemed reasonable and acceptable for him to freak out a little.

"I really hope so." Alec said with a shaky smile. Isabelle leaned forward to hug him tightly.

"It's gonna be okay."

"You're alright with your brother having a baby?" Alec chuckled. Isabelle leaned away from him a minute and gave a tiny smile. She leaned back in to embrace him again.

"I love you bubby."

"I love you sissy."
