User blog:Hunterinpurgatory/Dean unable to hunt after release from Purgatory?

Just wanted to use this blog to discuss ways writers could limit Dean's time in Purgatory while still having Sam hunt on his own for large amounts of the season. One way would be for Dean to be released from Purgatory by this season's Big Bad and told he will be sent back if he tries to stop its plans. As a result, Sam makes Dean do the research while he does the actual hunting. Either that or Dean comes back from Purgatory broken and a million times worse than after he was in Hell(think Sam after losing his wall times a hundred) and gives up hunting completely until Sam is in such danger that he must come out of permanent retirement to save him. Thoughts? Also, feel free to discuss who Sam would partner with on hunts w/ Dean gone or in retirement.
