Lol, I'm totally with you there.
I think that he's based on a fantasy of Cassandra Clare's...wishing she had gotten a little more action when she was young'n.
Regardless, Jace is teh Frickin Shyt. I wish I knew a guy like him. :/ Fucker.
And of course, after knowing a guy like him, I wish he had the hots for me, lol.
Well, I've got my whole life ahead of me. One can only hope...
