Changes

As [[Castiel ]] steps through the tear in space and time and finds himself in another an [[alternate universe]], he is quickly beset by a [[tempter demon]], who is about to kill him when he is saved that Earth's Bobby Singer, much to his shock.

Later when [[Sam ]] and [[Dean ]] set through the rift, to their amazement they are met by Bobby on the other side. However, this Bobby Singer does not recognize them, telling them the only Winchester he knew of was named [[John]], who has been dead for 40 forty years, and only knows of him through another hunter named [[Mary Campbell]], who was killed by [[Azazel 10 ]] ten years prior. Bobby goes on to tell them that when the rift opened up, alarms at his place started going off, and when went to investigate he found Castiel being attacked by a tempter demon, but realizing something was different with Castiel compared to other angels in that universe, he didn't shoot him on sight, and learned that the rift was a gateway to another universe where the Apocalypse has not happened. But tells them that he doesn't mind this Earth, as it allows to live his hobby and passion of killing angels, telling them it will only be a matter of time before the angels get wind of the rift and come down to investigate, but that he will be ready with his trusty gun "Rufus" and a hundred rounds of angel-killing bullets.
