Think Fast

"He tried to change you, Marlize. But I think that deep down, you are still an optimist. You still believe in humanity. And I believe in you. You asked me what I was willing to do for my husband. And now I'm gonna ask you... what are you willing to do for the world?"

When DeVoe assaults an A.R.G.U.S. facility to complete his Enlightenment Machine, Barry realizes the only way he can stop him is if he allows Cisco and Caitlin to accompany him into the facility.

Trivia

• When DeVoe (disguised as John Diggle) goes to A.R.G.U.S., a guard says "Elvis, Banana" DeVoe then responds "Hendricks, Spaghetti"; a word association test that Barry had been given in the penultimate episode of season 3 when he and Leonard Snart had broken into A.R.G.U.S. to steal the Dominators' energy source being stored there. With a fake I.D. created by Cisco, and H.R.'s facial transmogrification device, Barry (impersonating Lyla Michaels) had been been able to get past most of the security at the facility's entrance. However, the when the guard gave the word association test, Barry was unable to give the correct answer, and thus, had to fight his way through security.
  • Both sets of words relate to a celebrity's favorite food;
    • "Elvis, Banana" is a reference to Elvis Presley, and his love of peanut butter, banana and sometimes bacon sandwiches.
    • "Hendricks, Spaghetti" refers to Christina Hendricks and her love of spaghetti.
• When DeVoe is attacking A.R.G.U.S., he plays and moves to part 2 of the Messiah Highlights.
• Diggle's extreme susceptibility to motion sickness is once again witnessed, with Iris, Caitlin, and Cisco preparing a trash can and water bottle for his inevitable bout of vomiting following Barry superspeeding him into S.T.A.R. Labs.
• Cisco likens DeVoe to the Legion of Doom, suggesting they send the "Super Friends" to defeat him. The "Super Friends" typically refers to the Justice League of America, the name originating from the TV series of the same name. In that series, the Legion of Doom were also an enemy of the Super Friends.
• When the delivery guy brings Joe and Cecile's food, he goes to compliment the house. Joe suggests the phrase "bitchin'", yet another callback to the season premiere in which the team decodes a message from an entranced Barry says "this house is bitchin'".
• This is the second episode of the Arrowverse to feature John Diggle without Oliver Queen, the first being "King Shark".
