If clowns don’t scare you, maybe murderous mannequins do.  In “Mannequin 3: The Reckoning,” Sam wakes up from his vision of hell and both him and Dean are startled that the wall in his mind has already started to crumble.  Having recuperated as much as possible, the boys head to Paterson, New Jersey to investigate the murder of a janitor that occurred off hours in a locked school.  While trying to determine what happened, another man dies during the night working security at a factory.  Both victims had identical cuts on their foreheads but the boys are having trouble finding any other clues that tie them together.   They soon find out that a factory worker named Rose went missing but they don’t have much else to go on at this point.

In the meantime Dean gets a call from Ben who tells him that his mother’s in trouble.  When pressed for information, Ben tells him that Lisa refuses to get out of bed and has locked herself in her bedroom.  Dean rushes to their home while Sam stays and to continue his investigation in New Jersey. 

When Dean arrives, Lisa answers the door and, dressed for an evening out on the town she’s less than pleased to see him.  He finds out that Ben called him because his mother’s going out on a date with another man and he wants Dean to come back instead.  The two have a father-son talk but it leaves Dean with a lot to think about in terms of what family means to him.

While Sam waits for Dean’s return he begins interviewing factory employees and comes across one that acts suspiciously.  Johnny doesn’t give Sam straight answers and acts nervous when questioned.   That night Johnny’s talking on the phone to someone, telling him that he thinks the feds know what’s going on when suddenly the same cut mark appears on his forehead.  Sam then grabs him and brings him to the break room where he lines the walls and window sills with salt to protect him.  Sam finally gets Johnny to confess to what happened:  they made Rose think she had a secret admirer, lured her to an apartment, set up a mannequin at the table and then laughed about her humiliation.  She went to storm out, one of the men grabbed her arm and then she fell, cracking her head on the coffee table.  The boys decided to cover up her death.   Sam asks where Rose is buried and Johnny tells him.  He orders Johnny to stay behind the salt lines and goes off to salt and burn the body.  Once this occurs he calls Johnny to tell him he’s safe.

Unfortunately, no one could’ve suspected that Johnny’s girlfriend is a mannequin kept in his apartment.  And that night, she comes to life and kills him.

Sam returns to Isabelle (Rose’s sister) and realizes she’s the common denominator.  She’s visited all of the crime scenes in the last week, thus making her the link between all of the murders.  In addition, he finds out that Rose donated a kidney to Isabelle when they were teenagers and that is keeping her tethered to this world.

The brothers reunite to discuss how to save Isabelle and get rid of Rose’s ghost.  They decide on hoodoo right around the time Rose’s ghost possesses the Impala and chases down Dean.  The car finally stops when it crashes through a store front, landing a huge shard of glass into Isabelle’s abdomen.  Rose’s ghost appears and apologizes.  Afterward Isabelle dies.

Afterward the boys can’t help but feel bad after the result of this last job, and they try to make themselves feel better by knowing that at least they do save people from time to time.

Be sure to tune in for next week’s episode.  In “The French Mistake” Sam and Dean are transported to an alternate reality.  Raphael (guest star Lanette Ware) launches an attack on Castiel (Misha Collins) and his allies, sending a particularly frightening angelic hitman (guest star Carlos Sanz) after Balthazar (guest star Sebastian Roche), Sam (Jared Padalecki) and Dean (Jensen Ackles). In an effort to protect the brothers, Balthazar sends them to an alternate universe where they are the stars of a TV show called ‘Supernatural’ and they are actors named “Jensen Ackles” and “Jared Padalecki.” The brothers are confused when Castiel appears to be a tweet-happy actor named Misha Collins and Sam is married to Ruby (Genevieve Cortese).
