what do you think guys?...honestly im really confused at the ending of season 5 cause first sam or should i say lucifer which is in sammy's body is trapped together with michael..and in the last part sammy appeared...wait..was it sammy or lucifer?..and if lucifer or sammy had escaped in the pit where is michael?..and also one more thing that confused me is "chuck" the so called "prophet"..why did he vanished all of a sudden..?
