4. Cain would beat Michael in a fight to the death? I'm sorry but I strongly disagree with you there. Cain hasn't shown anything that makes me believe he can kill a normal angel. He couldn't even kill a regular angel with a weakened grace. Let alone the strongest archangel. You don't think Michael would remove the mark and then kill Cain? 5. Plots that were edited or removed such as Sam and Ruby getting married. 6. Castiel was supposed to die in "On The Head Of A Pin" then later in "Swan Song". How would he have died if plans weren't changed.
