User blog:Nightband/Dick in Purgatory

Ok, while I loved the ending of Season 7, Dean and Cas ending in Purgatory after killing DIck, I think there may be a plot hole in there.

When Dean asks where they are Cas responds with "where would he [DIck] go in death?"

But the thing is, the Leviathan have no souls, they were created before God INVENTED souls. For him to have gone to Purgatory he would have needed a soul, which he doesn't. Castiel's comment may have created a plothole in the show.

My theory is that they ended up there because of the weapon's side effect, which Crowley briefly mentions, but I don't know what to make of Cas's comment.

What are your thoughts on that?
