Armageddon, Part 4

"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.

"So I ran back to the year 2013 and made sure that I was the one struck by lightning. I was the one that Iris West wrote about as the Streak. I led Team Flash. I was the one Iris West fell in love with. I stole your life! And because every hero needs a villain... I created that, too."

—Eobard Thawne to Barry Allen

Trivia

• The following occurred in the Reverse-Flashpoint caused by Eobard Thawne are:
  • Eobard Thawne was chosen by the Speed Force.
  • Barry Allen is Reverse-Flash and assisted Damien Darhk in killing Ray Palmer, Nate Heywood, Sara Lance, the rest of the Legends, and Cisco Ramon. Damien was later released from prison due to a technicality much to the dismay of the people.
  • Ryan Choi has become a vigilante.
  • Frost and Mark Blaine are married.
  • Allegra Garcia and Chester P. Runk used to date until it didn't work out which they noted after a devastating fight with the Legion of Doom.
  • Ryan Wilder and Sophie Moore are married and planning to adopt.
  • Joe West dies from falling on the train tracks thanks to Reverse-Flash.
• The Reverse-Flash has a new suit that is much closer of a match to Barry's current suit.
• The Reverse-Flash suit coming out of the Flash ring is a reference to the Flashpoint comics.
• This is Damien Darhk's first appearance on The Flash since "Legends of Today".
• Damien Darhk's magic not working on both Frost and Mark Blaine thanks to John Constantine before he fight them with hand-to-hand combat is very similar to what happened with him during his final battle with Oliver Queen in "Schism" when his magic couldn't work on him thanks to a magical tattoo that Oliver got from Constantine.
• Ryan mentions a dealing with a "lady [speedster] in red". While this seems to imply a version of Red Death as he was a villain to both Batman and Flash, Ryan also could be referring to Trajectory or Jesse Quick.
• This is the first time in the Arrowverse that Barry and Darhk have interacted.

Goofs

• The scene at the beginning of the episode in which Eobard gives his speech and Barry arrives has some minor differences compared to the scene as it was shown at the end of the previous episode, "Armageddon, Part 3".
  • This is the second episode in which one of Eobard's speeches from a previous episode has had minor differences when recreated, the first being "Therefore I Am", which recreated the press conference scene from "Pilot".
• Deon Owens mentioned that Eobard used the Negative Still Force to kill Joe but while Eobard was explaining how he killed Joe to Barry, the flashback of him show him running at superspeed pushing Joe on the train tracks. It's either Deon made a mistake to believe that Eobard uses the Negative Still Force in which Deon who usually uses the Still Force ended picked up negative tachyons in which he believed that Eobard uses the Negative Still Force to kill Joe or Eobard actually gained access to the Negative Still Force during Joe's death even though the flashback shows Eobard using his superspeed.
