The Clave discussion

So here is a thought I just had. I am re-reading City of Lost Souls, before I get into City of Heavenly Fire. Jace is a direct descendant of Will and Tessa. This means that Jace has a warlock for a great-great grandmother. Tessa's father was a greater demon (who is unknown). So Jace has the blood of a greater demon in him. And to top it all off, he has the blood of Ithuriel also in him, as a result of Valentine's experimentation in vitro. So he has demon and angel blood. I wonder if Valentine knew his family history and that is why he used Jace's mother for his experiment. Just a thought.

That's a really good theory and I wouldn't be surprised if that's why Jace is so powerful
