Clary's jealousy of Simon and Isabelle might just drive her... to murder! Okay, okay, so we're being a bit dramatic. But notice how Clary bottles up her jealousy and blames it on fatigue. She's afraid to share how she really feels—even with her best friend.

This story told by Jace says a lot about why he puts up a prickly façade to keep people away. He's both scared of loving and being loved. Vampires on the other hand? Not scary at all.

We wish this revelation would give Clary the self-confidence to realize that she, too, will age into an attractive woman once she's past her awkward teen years. We really wish she'd just get over her whole hang-up on appearance altogether, but at least this is a small step in the right direction.
