"The Elongated Knight Rises" is the eleventh episode of the fourth season of The Flash, and the eightieth episode overall. It aired on January 23, 2018.


When a familiar villain returns to terrorize Central City, Ralph must rise up to defend the innocent while Barry is detained by his trial. Meanwhile, Barry searches for the strength to keep his optimism alive in the face of his new circumstances.[1]




  • The title references the final entry in The Dark Knight trilogy, The Dark Knight Rises, which also sees a superhero battle his fear and grow stronger.
  • After seeing his father writing "Henry Allen was here" on the wall of the jail cell, Barry writes "So was Barry". This is a possible nod to "Brooks was here" and "So was Red", from the 1994 film The Shawshank Redemption.
    • When Barry met Axel and said that he was innocent, Axel replied that everyone there was innocent, another possible reference to the scene from the film where Red meets Andy.
  • While trying to come up with a superhero name while talking to the suicide bomber, Ralph references to two Marvel Comics Superheroes.
    • He says "It's your friendly neighborhood superhero," referencing Spider-Man.
    • He continues that phrase with "Mister..." but stops there, referencing Mister Fantastic, a Marvel superhero with similar powers.
      • It's a parallel to a similar situation back in "Flash vs. Arrow" when Iris asked the Flash what his real name was and the reply was Ralph coincidentally Elongated Man's civilian first name.
  • When Ralph got burnt by the Axid, Cisco says that he would not have got the burn if he had Xenomorph blood as in the 1979 film Alien.
  • Axel calls Ralph "strong-arm Stretch Armstrong" as a reference to the action figure Stretch Armstrong.
  • This is the second time we have seen "Mystery Girl."
    • The first time was in Crisis on Earth X Part 1.
    • It is also seen that the "Mystery Girl" is writing in a notebook, the same symbols that Barry was writing when he came out of the speed force.
