User blog:Noctosphere/What if Sera Gamble stayed?

As you may have noticed in season 6 and 7, Sera Gamble focused a lot on Purgatory.

So it makes me wonder, what would Supernatural look like if Sera Gamble stayed?

Maybe Dean and Castiel would have stayed longer in Purgatory, like half of season 8.

So? Am I the only one who wonder what Supernatural would have looked like if Sera Gamble stayed longer?

If you do, what is your fan fiction of Supernatural around the Purgatory that could have been created by Sera Gamble?
