Are we sure that these aren't signs of the Apocalypse? I mean we narrowly avoided any such happenings when the world's clocks turned to 2000....Maybe we really need the Winchesters...especially Dean. Sam too but definitely DEAN Winchester! It may just be that because all of those seals are opening the Four Horsemen of the apocalypse are nigh.....and we know that Death/Methos is only semi-reformed....Grab your cans of salt, ladies and gentlemen these may very well be the end of days.
