Aline Penhallow

Aline Penhallow, Sebastian's cousin. She is Isabelle's foil. She is conservative on the subject of Downworlders as well as being curious about many subjects, especially vampires. Aline has a short-lived crush on Jace, to which she "makes a move" and proves to be a source of aggravation for Clary when she walks in on them kissing. However, Aline soon explains to Clary and Isabelle that Jace is "not her type". In City of Glass, she is savagely attacked by a demon, but lives through it.
