1) At the end of the episode "The French Mistake", Castiel, empowered by the Heaven's Weapons, advised Raphael to better leave now, otherwise he would die. So, why did Castiel still need the Purgatoy souls if he couls kill Raphael with the Heaven Weapon's ? What happend to the weapons ?

2) It seems, Lucifer and Michael were unaffected by the Angel banishing spell, because unlinke all the other angels, they were not "expelled" to the earth. Did Lucifer and Michael still have their wings after Metatron casted all the angels out of heaven ?

3) Lets assume, an Angel, for example Michael, takes a time travel to the 18th century. One Michael is in heaven and the other arrived from the future ...  So, are there 2 Michaels now ?
