Trivia

• The title is a reference to Barry's final line as the CCPD show up to arrest him right after he realizes that Clifford DeVoe, now possessing Dominic Lanse's body, planted knives along with his old body to make it look as if Barry had killed him.
• Cisco likens Harry to Ebenezer Scrooge and the Grinch. In reply, Harry claims that "you're a mean one, I wouldn't touch you with a 39 and a half foot pole", quoting the song "You're a Mean One, Mr. Grinch" from the 1966 TV special Dr. Seuss' How the Grinch Stole Christmas!.
• Cisco calls both Harry and Ralph humbugs, referencing Ebenezer Scrooge's catchphrase in the Charles Dickens novella A Christmas Carol.
  • Cisco claims this as a "Festivus miracle", a phrase commonly used by Kramer in the TV series Seinfeld.
• When Amunet prevents Caitlin from transforming into Killer Frost, she quips that "Frosty melted away", referencing the 1969 TV special Frosty the Snowman in which the protagonist melts.
• Cisco calls Amunet an "evil Mary Poppins", referencing her English accent.
• When DeVoe (disguised as Dominic) goes to describe the West house, Cisco suggests "bitchin'", a callback to the season premiere, "The Flash Reborn", in which a decoded message from a discombobulated Barry reads "This house is bitchin'".
• DeVoe gains the ability of telepathy through his transferring his mind and consciousness into the body of Dominic. In the DC comics, DeVoe had the ability of telepathy, however, Barry Allen is immune to telepathy.
