A/N/ This is really only what Jace's thinking when Valentine tells him he and Clary are related.

"Yes, Jace. Jocelyn is your mother."

I stared at my father, not fully comphrehending. Did that mean Clary was adopted? Or...

"And Clary," I noticed how she stiffened, refusing to meet my eyes, as if she was hiding something...

"Clary is your sister."

I felt my wineglass tip and the purple wine slosh over my sleeve. I hardly noticed, though. I felt bile rise up in my throat and wondered for a moment if I was going to be sick.

"No." my voice was muffled. "Please tell me it isn't true."

Memories flashed behind my eyelids; kissing Clary in the greenhouse, making Clary laugh, feeling like I was at home with her...

We couldn't be related.

If I pictured Isabelle in all those memories, I would get swearing instead of laughter, feeling annoyed insteadof bliss...

And if I ever tried to kiss her she'd whip me with her golden whip.

I opened my eyes to see Clary kneeling in front of me. She swallowed audibly. "I can't say that," she whispered. She knew?

I recalled all those times I'd wanted a little brother or older brother when I lived with Father.

I'd always had a sibling. A sister.

Clary was my baby sister.

Okay, that was a little short.

But I liked it. R&R
