User blog comment:Hunterinpurgatory/How will Dean get out of Purgatory?/@comment-5123006-20120616202559

I think it would be interesting if Dean and Cas had to open the gate from inside of Purgatory, but I doubt the producers would do that. I also think being rescued by God is quite possible, but I hope they don't do that as it would be a literal deus ex machina.
