Just five more questions and that'll be it then for a while:


 * 1) How and when were the angel blades created?
 * 2) It was established in Season 4-7 that humans were apparently created through evolution, but now in Season 9-10, the Garden of Eden and Adam and Eve are being introduced into the mythos. Can the writers bridge some of the gaps here?
 * 3) Could the demon knife actually kill Lilith?
 * 4) When did War, Famine and Pestilence each come into existence?
 * 5) Can a regular angel blade kill an archangel, or does it need to be an archangel blade like Gabriel's?
