Jesus, this chick never fucking learns! Clary just keeps running headlong into dangerous situations. While, arrogantly, thinking that she knows everything. This would be hilarious if it wasn’t just so damn pathetic at this point. Anyone who has even tangentially watched, or read any vampire related materials over the years knows that newly risen vampires are basically ravaging monsters with zero control. Since humans are their primary food source, Clary as the closest human, was in danger of getting eaten.
But does any of that logic penetrates her thick skull? No, because she’s a dumb, and arrogant one-dimensional character . Who is severely lacking the ability to ever learn from, even one of, her mistakes.
