I think time will go haywire in Purgatory, Dean thinks it is only five days when it is actually five months. Sam will meanwhile have to team up with Crowley and Meg to harness his demonic powers to open the gate of Purgatory.

Maybe they're in there for ten eps and the rest of the ten eps is about the Big Bads coming onto Earth and final ep is WTF shall we do now the Biggie is come??
