Armageddon, Part 5

"Things were looking a little grim, but part of me was, admittedly, a little excited for a 'reunion' of old friends." —Cisco Ramon[src] This episode is part of a larger crossover series, Armageddon.

"You don't think I want to see him dead either? 'Cause I do. If I learned one thing being a cop, it's that you can't just protect the people you think are good. You have to protect everyone. That's what heroes do."
"I know that."
"Do you? A hero is not just in the name, Barry, or in a red suit. It's the choices we make that decide who and what we become. You know that."

—Joe West and Barry Allen

Trivia

• In continuity of the Arrowverse, Mia time travels to 2021 from 2042, two years after William Clayton's abduction in "Green Arrow & The Canaries", set in 2040.
• This is the first episode to feature a one-on-one scene between Caitlin Snow and Eobard Thawne, not counting the deleted scene from "The Trap".
• The boots were added to the Flash's suit in this episode, having previously been referenced in the Season 2 episode "Running to Stand Still" with drawings at James Jesse/Trickster's prison cell.
• Eobard's backstory seems to draw from his DC Rebirth origins, in which Eobard would endanger people and then save them to make himself appear as a hero.
• Eobard's origin story here conflicts with what his original version said in Reverse-Flash Returns. His original backstory was that Eobard became Reverse-Flash after the first time he time traveled and he realized he was never going to be the Flash. However, here he claims that the reason he became the Reverse-Flash was because The Flash time traveled to the future and humiliated Eobard by saving the crowd that Eobard was supposed to save.
  • This was most likely a Post-Crisis change after Oliver Queen and Paragons reset the multiverse.
• Eobard implies that his time lacks the abundance of threats and criminals that Barry's does; which would explain his petty rage at the Flash stealing his moment of glory. Because he would only be seen as a pretender and copycat after the Flash.
• Iris West-Allen discovered clues to William's whereabouts from redacted documents in Berlin, related to markings seen on the altered Hōzen Mia brought with her from the future. Mia also mentioned she would ask her mother, Felicity Smoak, to assist her in declassifying the files.
  • The implication of markings found on the future Hōzen, tied to Trevor's Deathstroke gang and their unknown female benefactor in 2040, originating from a location in 2021 strongly infers that the antagonists of Green Arrow & The Canaries are associated with an unspecified faction in Berlin from twenty years prior. As this relates to William's future kidnapping, Mia presumably would be attempting to undo the events leading to William's kidnapping and John Diggle, Jr.'s brainwashing in 2040.
• Nora Darhk expresses sorrow at having to lose her father again, referencing the events of "Mr. Parker's Cul-De-Sac".

Goofs

• Despero attempting to destroy the city in order to kill Thawne contradicts him telling Barry that Thawne had to be erased, not killed, in order to ensure his death earlier in the episode.
  • However, he might have changed his mind out of rage for Barry.
• The ending shot shows Bart and Nora appearing in a photo from New Year's Eve in 2014. However, as seen in "Impulsive Excessive Disorder", the picture was actually taken on New Year's Eve in 2013.
