Every change Nora and Bart made to the timeline

Warning! SPOILERS for the flash season 8, episode 6, “Excessive Impulsive Disorder”.

Nora and Bart West-Allen made a number of accidental timeline changes in the flash season 8 episode “Excessive Impulsive Disorder”. It’s an integral part of a speedster’s life in the Arrowverse, where it’s nearly impossible for someone to time travel without unintended consequences. Even speed veterans have a hard time dealing with it and the first Flash, Jay Garrick, compared the whole process to gluing a broken coffee cup, saying that “no matter how hard you try, it’ll never be exactly like this.”


The events of “Excessive Impulsive Disorder” are from the final story arc of the flash season 7, where Nora “XS” West-Allen (Jessica Parker Kennedy) and Bart “Impulse” West-Allen (Jordan Fisher) traveled back in time from the year 2049 to prevent Impulse’s nemesis, Godspeed, to change the timeline. Many fans have wondered how they were able to do this without apparent side effects, considering the issues caused in previous seasons of the flash when their father, Barry Allen (Grant Gustin) attempted to change his past while dealing with other villainous speedsters. “Impulsive Excessive Disorder” answered that question, setting the two young heroes in a race against time to undo the unwanted changes caused by their trip to 2021 with another trip to 2013.

Nora and Bart made a number of minor changes when they visited in 2013 that established several things in the status quo of the flash season 1. Despite this, the episode ended well with the future timeline of 2049 seemingly secure. However, it seems likely that the trip will facilitate further changes in the future, especially regarding Bart’s romance with a young physicist named Avery who may have a greater destiny ahead of her within the Flash family. Here’s the rundown of every change Bart and Nora made to the Arrowverse timeline in the flash season 8.

Jay Garrick is alive and well in 2049, but married to another woman

Back home in 2049, Nora and Bart were stunned to be greeted by their honorary uncle Jay Garrick (John Wesley Shipp) as he returned from a food errand for a family dinner. This was surprising as Jay Garrick would have been killed by Godspeed at some point in the future, fueling Impulse’s hatred for the sinister speedster. However, the siblings’ joy at Jay Garrick’s return to shine turned to horror when he referenced “Aunt Roselate due to a botany club meeting. The two quickly determined that reality had been rewritten so that Jay had never met Dr. Joan Williams (Michelle Harrison) who became his wife in the timeline original and traveled to the Flash Museum to determine what otherwise might have been changed by their trip down memory lane.

The Flash Museum records events that Nora and Bart don’t remember

A quick scan of the recordings detailing the many battles of The Flash and his allies at the Flash Museum’s Hall of Heroes confirmed what Nora feared most. In addition to causing their Uncle Jay to never meet Aunt Joan, the siblings’ 2021 trip had a butterfly effect causing many events in their father’s past that neither of them remembered. These included a version of the Arrowverse’s Trickster invading Tibet and a 2047 corruption scandal involving Mayor Anthony Bellows Jr., who was Mayor Bellows’ son The Flash and Elongated Man arrested in the flash season 4. There was also a recording of their grandfather, Joe West (Jesse L. Martin), as Central City’s police chief in 2016, several years before he was supposed to become the chief of the CCPD in their original schedule.

Booster Gold was honored at the White House in 2032

A Flash Museum recording involving a hero named Booster Gold being honored in the White House in 2032 was dismissed by Nora and Bart as unimportant, as neither of them recalled ever hearing of a hero named Booster Gold (Donald do). That was remarkable in itself, given their otherwise encyclopedic knowledge of superhero history. This suggests that Booster Gold, which was introduced to the Arrowverse recently in Legends of tomorrowmight have remained an anonymous time traveler until the siblings’ time travel changed his fate and made him a public figure.

Bart then proved Avery’s theories correct when he revealed himself to be a time traveler from the future and asked for his help in figuring out how to avoid the paradoxes he and his sister had created.

Bart and Nora determined that the trigger for the chain of changes to their timeline was that Joe West was shot while confronting a bank robber on December 31, 2013. It was a fairly straightforward matter for Bart to move Joe slightly at high speed, allowing the ball to pass by him safely. Unfortunately, this action led to another unpredictable consequence, with his and Nora’s argument about moving Joe instead of the bullet being heard by an unseen enemy.
