Chapter 1: With the Winchesters
Many centuries later, when the world had moved on, humanity had spread and Mary and John Winchester were raising their son Dean, someone unexpected appeared in their lives. It was . . . a moose, a gangly baby moose that was all limbs and little balance. The little one appeared one morning during a hot summer day. It was just lying there hot and tucked out and only about a month old. John and Mary stared out at it for several minutes until little Dean pushed past both of them, shrieking in delight at the sight of the wee moose. John and Mary watched their four year old scampering around the little moose which stared at him, seemingly amused by the little boy's antics. After several minutes, Dean ran over to his parents, big eyes looking pleadingly up at them.
"Can we keep him…please?" Dean asked. John and Mary looked at their little boy then at the forlorn image of an overheating baby moose.
"It seems harmless." John commented. Mary looked from the moose to him.
"Lots of things seem harmless, but it hasn't done anything…yet." Mary looked critically at the moose which seemed to be trying to give them it's most innocent look. Mary sighed.
"Fine, it can stay but any sign of danger and it's gone." Mary declared. Dean smiled and hugged the moose.
If you were to look in the photo album for the Winchester family from June 1983, you would see a few weeks of photos with the whole family plus one moose then suddenly the entire Winchester family plus one dark haired baby boy.
John and Mary didn't quite know what to make of a shapeshifting moose but the child seemed harmless and appeared to have no memory of being anything but a normal human boy and a member of the Winchester family. Sam Winchester grew up a perfectly normal human despite the death of Mary Winchester and the fact that the rest of his family were insane monster hunters. Sam was accepting of his life until he encountered…the angels.
