In a reality where Cas has rewritten history so none of his mistakes post- Dean Winchester exist, everyone is relatively happy. Dean is not in hell, Sam, Bobby, Ellen and Jo are alive, Heaven is fixed (for heaven anyway) and the apocalypse, the leviathan and everything else didnβt happen.
Castiel is now human thanks to the spell needed to create this reality, he is also alone. In saving Deanβs happiness, he had to lose his best friend and give up heaven all over again. Heβs ok though, he has a job, he has an apartment, heβs good. Or thatβs what he tells himself until Dean strolls into town.
Turns out fate isnβt quite as easy to change as they always thought.
