In Montana, Bobby is interrogating the leviathan Chet and trying to find a means to destroy him. Chet suggests Bobby, Dean and Sam to watch the news on the television and they discover that two leviathans have cloned the Winchester brothers and are going on a crime spree in the same sequence of the cases that the brothers worked. Further they are the second most wanted in the United States and there is a manhunt of the FBI due to the murders of their doppelgangers.
Dean and Sam head to Ankeny, Iowa, and when they see the doppelgangers, Sheriff Osborne and his men arrest the Winchester brothers. Dean asks the sheriff to use his right of a phone call. Meanwhile, Sheriff Jody Mills visits Bobby that is still trying to destroy Chet. Out of the blue, a liquid drops on Chet arm and melts his flesh. Bobby finds Jody cleaning the floor with a sodium borate based detergent and he learns that decapitation associated to sodium borate can destroy the evil leviathans.
"Slash Fiction" is one of the best episodes of Supernatural, with a witty story of doppelgangers. The ironic means to destroy the powerful creatures is hilarious and now Crowley is back proclaiming that he is "The king of Hell". The leviathans are climbing positions in the society and Dick Roman seems to be a very powerful enemy of Dean, Sam and Bobby. The revelation to Sam that Dean has betrayed him and killed Amy was expected and now Sam and Dean are estranged. My vote is nine.
