good grief sethrp 1 and you completely miss the point . the girl be only see briefly specifically because she be the one who be go to kill herself . everyone else be so wrap up in their own story they do not notice her and nor do we . a one of the other student say at the end be all so wrap up in our own problem we do not notice what go on for someone else . the director himself say if he have kill off one of the others and it would have suggest their problem be bad than someone else . the whole point of kill kelly be that she be unnoticed by all of u . get it now .
