As far as we know the Colt can kill Jesse Turner. Only Lucifer has been identified as one of the five things in creation he referred to. As he is an archangel, it is logical to assume his brothers are also invulnerable. Unless there is a fifth archangel yet to be revealed which I find unlkely, we can only guess who thefifth  remaining thing could be.
