They call themselves Team Free Will, and the name seemed to fit. They were just making it up as they went, ignoring the script and the whole goddamn plan. So maybe he took it for granted. That free will was actually a thing that he, Dean Winchester, actually had. Because no apocalypse, no saying yes to Michael, that's proof right?

POST-10x05 After Calliope's defeat, Dean admits, "This has been educational – seeing the story from your perspective." But what did he mean? AU after 10x05. Dean wants to forget about "Destiel" and Sam can't help but bring it up all the time. Then, the angel himself visits and Dean prays that Sam will shut up so he doesn't have to explain it to Cas.
