I always had this ringing question ever since the beginning of the 4th season, why is Dean's body the way it is? By that, first off I mean, why isn't he rotting? He was dead for 4 months and yet no deterioration, also how come Castiel's hand print is on his body when he pulled his soul out of hell?
Finally, why did Bobby and Sam bury his body? I thought a hunters' death was "salt & burn". John Winchester, Issac(season 3 episode 1), probably many others were sent off that way.
