This book. This is Dad's single most valuable possession—everything he knows about every evil thing is in here. And he's passed it on to us. I think he wants us to pick up where he left off. You know, saving people, hunting things. The family business.

John Winchester created a journal in which he placed all of his most important information that he learned during his career as a hunter.

Overview[]

Along with the laptop that Sam owned, the journal was his and Dean's most valuable asset in finding and killing supernatural entities. The journal was John's "single, most valuable possession". The journal is believed to be extensive and is also believed to hold all of the information needed to defeat Azazel whom he had spent his entire hunting career looking for.

On several occasions, it has been shown that the journal actually lacks information on certain things such as John's shtriga hunt and the ghoul hunt that led to him meeting Kate Milligan. In the latter case, the information had been removed to protect Kate and his son Adam, in the former he kept it out of the journal due to how close the shtriga came to killing Sam.

In First Born, the journal is shown to at least in one case, point at John's Lock-Up holding more information on the case referenced in the journal. A "T" in the margin stood for Tara, the hunter John worked the case with.

In later seasons, particularly after they gain access to the Men of Letters bunker, Sam and Dean stop using the journal for information. The last time it is used for information for years is in Season 9's First Born when Dean and Crowley use the journal to find out about John hunting Abaddon's protégé. The journal is briefly seen in Season 12 when its given to Mary, but isn't used for information until Season 13's The Rising Son when Sam looks up the Hell Gate leading to the Shedim and later on, the Princes of Hell. This is a gap of around three and a half years of the Winchesters not using the journal on a case.

History[]

Background[]

The journal was originally ordered by Henry Winchester in anticipation of his initiation into the Men of Letters. However, the Men of Letters were massacred by the Knight of Hell Abaddon on the night of Henry's initiation and Henry escaped through time to the year 2013. The journal arrived after Henry's disappearance and despite believing his father to have run out on him, his son John hung onto it.

After the murder of his wife, John became a hunter in order to get revenge upon his wife's killer. John turned the journal into his own hunting journal after going to Missouri Moseley for answers, chronicling everything that he knew about various monsters and creatures, his hunt for Azazel and the various hunts he went on.

Season 1[]

In Pilot, John leaves the journal in his motel room in Jericho, California. Sam and Dean claim it and use it to research the Woman in White. John leaves the coordinates for Lost Creek on a page with Dean's name.

In Wendigo, after the Colorado Wendigo has taken all of their equipment, Sam takes Dean aside and asks for the journal which he opens to a page that shows John's entry on wendigos that has a drawing that John made along with all of the Anasazi symbols that the wendigo cannot cross. The two ultimately realize that John is not in Lost Creek but instead has left them the coordinates to another hunt.

Later, Dean shows the journal to Sam, telling him that John left it to them and he believes that John wants them to pick up where he left off, "saving people, hunting things, the family business."

In Phantom Traveler, Sam reads an exorcism from the journal in order to get rid of the Disaster Demon.

In Home, after believing that the thing that killed their mother has returned, the Winchesters attempt to retrace John's steps following the night of the fire. When Sam identifies one of the psychics in the area as Missouri Moseley, Dean remembers the first line in John's journal, "I went to Missouri and I learned the truth" and Sam and Dean realize that it refers to the psychic when they had previously thought that it meant the state of Missouri. There is a glimpse of the front cover of the journal displaying some of John's military history.

In Asylum, the boys find a reference in John’s journal to kids who disappeared from the south wing of the Asylum in 1972.

In The Benders, while investigating disappearances in Hibbing, Minnesota, Sam reads that in the journal, John suggests that the area could be the hunting grounds for a phantom attacker which is what he believes is causing the disappearances.

In Something Wicked, after Dean explains that what they are dealing with is a shtriga that John had failed to kill years before, Sam discovers that he wrote nothing about it in the journal.

In Provenance, John's journal records the history of deaths related to the haunted painting. Sam connects John's pattern with the painting's provenance.

In Dead Man's Blood, after learning of the death of Daniel Elkins in Colorado, Dean recognizes the name and finds Elkins' address and phone number in John's journal, causing them to realize that Elkins may be a hunter and a friend of their father and they decide to investigate.

Season 2[]

In In My Time of Dying, Sam looks up Reapers in the Journal. While he finds nothing to help Dean, Dean notes that reapers can alter human perception and thus deduces that Tessa is a reaper.

In Crossroad Blues, Dean recites an exorcism from the journal until the Crossroad Demon agrees to break Evan Hudson's deal.

In Croatoan, Sam speculates that what's happening to people could be related to a theory in John's journal, that Croatoan is the name of a demon associated with plague and pestilence, and calls what's going on "demonic germ warfare."

In Heart, Sam finds lore in John's journal that suggests that if the sire of someone who is a werewolf is killed, they will be released from the curse. Sam reads from the journal: “Lycanthropy might have a cure if you kill the werewolf who bit you severing the bloodline.” Sam and Dean's comments in the episode suggest they already knew of the theory and just consulted the journal to double-check exactly what it said. However, killing Glen fails to cure Madison. Later, they learn from Bobby Singer that he already knew that the theory wouldn't work, but it is unclear if John was ignorant of this or just never updated his journal to reflect it.

In Red Sky at Morning, Sam reads from the journal to summon the captain of the Espírito Santo.

Henry reads through the journal and feels guilty for abandoning John and decides to go back in time to prevent this from ever happening.

In Pac-Man Fever, looking for information on what could turn a man's insides to jelly and leave behind a blue handprint, Dean checks the journal while Sam and Charlie Bradbury check other sources.

In Last Holiday, the journal is seen amongst the various books that Sam is going through while researching.

In Carry On, after learning that vampires kidnapped a couple's children and were wearing masks, Dean recognizes the wife's drawing of the mask from John's journal. Looking through the journal on the hood of the Impala, Dean finds the entry on the case in 1986 when John was working a series of kidnappings along Route 77 in Akron, Canton and East Sparta, Ohio. Although John hadn't found much, the witness drew the vampires' masks which is also included in the journal entry. The journal states that the kids were taken and the adults that weren't killed had their tongues ripped out.

Sam deduces that if it is the same nest and the pattern holds, the vampires will target Canton next. Dean reads from the journal that the nest targets families living outside of town that are isolated and with kids usually between the ages of five and ten. By determining who in Canton matches the MO John noted in his journal, Sam and Dean are able to ambush the vampires at their next target and force one to lead them to the nest where they take out the remaining vampires and rescue the kids.

Non-Canon[]

Appearances[]

Trivia[]

  • It should be noted that in the published version John states it was given to him by another hunter who told him to write everything down. However, in the show it was originally meant for his father, and John inherited it when Henry disappeared. 
  • John pinned his Marine service medals on the inside cover. 
  • Following Dean using the journal to find out about Abaddon's protégé in season 9's First Born, the journal did not appear again until it was given to Mary Winchester in season 12's Mamma Mia. However, it was still not used for a case from First Born until season 13's The Rising Son when Sam found information on a Hell Gate Asmodeus was trying to open and later information on the Princes of Hell.
  • Prior to Season 10, the journal was used at least once a season to help on a case. There ended up being a gap of three whole seasons when the journal was not used to help on cases though it did make cameos in one of those seasons. In the other two, it did not appear at all.
  • The seated skeletal figure that appears in the journal with crossed arms is actually the Aztec god Mictlantecuhtli, it is unknown however if John had actually met Mictlantecuhtli in the past.

Real World[]

Alex Irvine, in association with Harper-Collins Books, wrote and published the official Supernatural: John Winchester's Journal, also available in E-book format. However it only loosely follows canon.
