Clary Fairchild: Does Isabelle always make dinner for you?

Jace Herondale: No, thank God. Most of the time the Lightwoods are here and Maryse, that's Isabelle's mother, she cooks for us. She's an amazing cook.

Clary Fairchild: Then how come she never taught Isabelle?

Jace Herondale: Because, it's only been recently that women have been Shadowhunters along with men. I mean, there have always been women in the Clave—mastering the runes, creating weaponry, teaching the Killing Arts—but only a few were warriors, ones with exceptional abilities. They had to fight to be trained. Maryse was a part of the first generation of Clave women who were trained as a matter of course—and I think she never taught Isabelle how to cook because she was afraid that if she did, Isabelle would be relegated to the kitchen permanently.

Clary Fairchild: Would she have been?

Jace Herondale: Not Isabelle. She's one of the best Shadowhunters I've ever known.
