Trivia

• The episode is a reference to a passage from the Bible, Exodus 7:19, in which God tells Moses that if he wills all of the Egyptians' water to become blood (as punishment for the Pharaoh keeping the Israelites in Egypt), then "there will be blood".
• This is the first Halloween episode of The Flash and the second in the Shared multiverse after the DC's Legends of Tomorrow episode, "Phone Home".
• Ralph says he is not looking to get married when he says he's going to find Sue Dearbon. Ironically, in the comics, he is married to her.
• Dr. Rodrigo says to Ramsey about Halloween "we're all endured to one good scare" is similar to the line from Halloween (1978) when Sheriff Brackett says to Laurie, "Everyone's entitled to one good scare."
• Frost uses the term "Post-Crisis", which is a common fandom term for the time after the comics Crisis on Infinite Earths.
