For the Arrow episode, see "Seeing Red".
"Even if we do, Cicada's not gonna stop killing. Not until—"
"—Until he's... dead.
"... I didn't say that."
"You didn't have to. The anger that I feel from you says it all."
"How am I supposed to feel?! He almost killed Nora!"
"Barry, I understand. I do. That man hurt your child. But this anger that you're feeling, I've felt it before. From Cicada. Honey, if you let it, this rage will consume you, the same way it's already consumed him.
Barry Allen and Cecile Horton
"Seeing Red" is the eleventh episode of the fifth season of The Flash, and the one-hundred-third episode overall. It aired on January 22, 2019.


During a battle with Cicada, Nora is severely injured. Due to Cicada's dampening powers, Nora's speed healing isn't working, leaving Barry and Iris scared for their daughter's future. Upset about his injured child, The Flash is filled with rage and confronts Cicada in a brutal battle. Meanwhile, Killer Frost keeps interfering with Caitlin’s work on the cure.[src]


  • This is the second episode to not feature Carlos Valdes as Cisco Ramon, although a photo of him (as Vibe) appears near the end of the episode.
  • This episode is titled exactly like the Arrow​ episode of the same name, the twentieth episode from the second season of that series. Also, in both instances, a loved one is killed/injured in each episode by getting stabbed through the back; Oliver's mother Moira getting killed by Slade, and Nora who is stabbed by Cicada except she survives, both heroes are also on the ground watching helplessly as their loved one gets killed/injured.
    • When Cicada stabs Nora in the back, it's similar to what Bane does to Batman in the "Knightfall" comics and the 2012 film The Dark Knight Rises .
      • Another similarity to an older episode of The Flash: Nora is paralyzed after getting stabbed in the back by Cicada making her immobile from the waist down, similar to what happens to her father in "Enter Zoom" when Zoom paralyzes Barry and makes him immobile, leaving him in a wheelchair in the next episode; "Gorilla Warfare"​.
  • This episode is a role reversal of "O Come, All Ye Thankful"​, when Barry almost gets killed by Weather Witch in front of his daughter; in this episode it's Nora who is almost killed by Cicada in front of her father.
  • Andre Tricoteux who plays Carl Bork, was also the suit-actor of Savitar's armored form in Season 3, and made several small appearances in episodes of the Arrowverse.
    • Carl Bork says, "You can't hurt Bork, but Bork can hurt you!" This is the exact line that Bork says on the cover of The Brave and the Bold #81, starring Batman and the Flash.
