Sam and Dean drew in a sharp breath. They were in the abandoned construction yard where they had fought earlier that day, back on Earth. The brothers were in their former bodies in their usual clothes. They looked over at the street; the impala and the gold convertible weren't wrecked, both were pristine. Other cars were driving by, but they were frozen in time. The people they could see walking down the block were frozen, as were the birds flying in the sky.
"You've saved this planet over and over again, but humanity is always in danger. When are you going to accept that this is a lost cause?" Cas asked.
"What are you talking about?" Sam was annoyed. "It was the angels and the demons that wanted the apocalypse, and this last time, it was the Leviathan! You can't blame humanity for the damage that the supernatural beings did." Sam remembered something. "Magic is what destroyed this world…What about the Earth we were sent to that didn't have monsters, and we were actors?" he asked.
"They wind up destroying themselves as well, further down the road. There are countless parallel universes in which God tried different scenarios, but in every scenario, humanity destroys itself. Humanity has proven to be a failed experiment over and over again, accept…in the world with monsters, you two have emerged as heroes. You have proven yourselves to be the most worthy of the species. Each of you have purified your souls in Hell, and have sacrificed yourselves countless times for love of family and for all mankind. God has given up trying to figure out how to keep humanity from destroying itself, but you two may choose to become the new Gods over the Earth. Since you are both human, and because there are two of you, perhaps together you can figure out how to cure the failings of the human spirit. Or you may choose to allow your souls to evolve and become a new life form in a higher state of consciousness, but humanity will cease to exist. If you choose the challenge of becoming the Gods of Earth, you will first be taught all the secrets of the cosmos; I will be your guide. The Earth will remain frozen in time, at any time you choose, until your training is complete."
"If we freeze time, can we make small changes to the lives of the people that are frozen?" Dean asked.
"Sure, if you're going to be God, why not?" Cas shrugged.
The brothers felt completely overwhelmed, yet flattered that God had so much faith in them. Their eyes lit up when Cas uttered the next sentence, "God has noticed your value of family, so you will each be permitted to select two souls to accompany you, and in addition, you may each select a mate." That sealed the deal. Cas already knew who they would pick.
This was going to be a no-brainer for Sam, but Dean had a decision to make. He loved Lisa and Ben dearly, but he had their memories erased. Besides, Lisa loved living in suburbia. But there was another old flame he had, who was fearless; she may enjoy learning about all the secrets of the cosmos…
