Timeline

Jeremy Fitzgerald is born in Texas, during November of 1968. He has a brother called Simon, who in time becomes The Purple Guy.

Freddy Fazbear’s Pizza suffers a massive string of child murders. The dead children are found in the suits of the Withered animatronics. There are about 20 children murdered at the Fazbear locations collectively.

Working as a guard for Freddy Fazbear, Jeremy Fitzgerald is bitten by Toy Bonnie at the FNaF2 location in 1987 at the age of 18.

A generous anonymous blood donor (who is highly suggested to be Simon, donating the blood of his victims) donates blood to Jeremy. After an experimental operation, he survives and recovers.

Jeremy forgets everything before the incident, and is bombarded with press attention. He moves to England and changes his name to Fritz Glade, so to avoid an unhealthy amount of press attention.

A number of events happen, in an order that is not entirely clear. At some point, Jeremy has a daughter called Bonnie Glade. it is unclear if she is adopted, or his own biological child.

Fritz begins to piece together what happened while recording messages for Strings. He begins to question the source of the donor blood, and if he should trust the Simon animatronic. he ends the conversation with a yes/no answer as to if he should trust Simon. The answer has no bearing on the ending that is achieved.

After discovering a Toy Bonnie mask, Bonnie puts on the mask and shows Fritz, stating “Look Dad”, a phrase repeated within the games. Fritz, having been bitten by Toy Bonnie in the past, suffers some form of PTSD breakdown, grabs a nearby axe and cuts off Bonnie’s head, arms and legs.

After realising his error, Fritz buries Bonnie underneath a Birdbath, while tossing the bloodied axe down a well.

The events of the main game happens.

At some point after the main gameplay, Simon convinces Fritz to build Blackrabbit. Blackrabbit then in turn kills Fritz.

Simon, having managed to escape from his restraints, leaves the office. He destroys Strings on his way out to ensure his existence is not known to those who will investigating the location, once Fritz’ body is discovered.
