Yet, another character in this godforsaken book who has the common sense of a fly. Seriously, this is in broad day light. I already went over how stupid Valentine was for attacking in a supposedly well to do residential neighborhood in the day time. He could have literally picked any other vampire and not have to worry about catching the attention of the mundane authority. Or hell, Valentine could have waited until Simon was walking alone and picked him off. The more convenient time was right after Simon left Magnus’s house a few chapters ago.
And Clary is proving that she is just as dumb as her father and brother. Because she’s shouting and acting a damn fool when a neighbor could be witnessing the entire thing, and risk bringing not only the NYPD but Simon’s mother into this mess. Also, Clary has a key. If she was so worried, all she had to do was open the door, close the door, and then start screaming for Simon.
Again, Clary is a complete and utter dumbass, but what else is new?
