Supernatural - Unforgiven

This was the second episode screened this week continuing the saga of the Winchester boys.  When Sam had his soul restored he did not have any memories of what he had been up to since he got out of the cage over a year ago.  This episode commences with him receieving a text with coordinates to a town on Rhode Island where they discover three women have gone missing.  When they investigate they discover Sam was here previously with Samuel hunting a monster called an Arachne because a number of men had gone missing. (Another crappy monster that is actually in human form!  When do they battle a monster that is not in human form?  Come On!).  When they were previously here, Sam and samuel had used the local Sherriff, Dobbs, as bait to capture the Arachne but it got him instead.  When they found the lair, they killed the Arachne and discovered all the bodies of men who had gone missing, but they were still alive.  Sam was uncaring and believed it would be better if they were dead, so he shot them all in cold blood.
While trying to discover what is going on now, Sam starts to remember and they realise that the women that have disappeared now were all bedded by Sam (whether they were married or not!  Go Sam!).  It is all a trap to lure Sam back for revenge, because ##SPOILER ALERT!!## the new Arachne is Sherriff Dobbs!  The bullet didn't kill him because he had already started to become an Arachne a year ago when Sam and Samuel found him. Sam used the only way to kill him, which is to decapitate him.
When the boys get home, because Sam has been trying to remember what happened on Rhode Island, he breaks through the wall that was built to stop him remembering his time in the cage and he collapses.  The episode finishes with him remembering burning alive in the cage.  A shocking conclusion!  How is this going to go for Sam next week?  Can't wait!
