Team Flash has to protect The Thinker's next target, a country musician who can cause shockwaves.
- All for Nothing: Despite all their efforts, in the end Team Flash couldn't save Izzy.
- All Your Powers Combined: DeVoe uses a combination of the other bus metas' powers, particularly Kilg%re's and Hazard's, to subdue Vibe, Flash, and Elongated Man in his first attempt to hijack Izzy's body.
- The Bad Guy Wins: The episode revolves around Team Flash's attempts to protect Izzy from DeVoe. In the end, they fail and DeVoe gets her body as planned.
- Call-Back:
- Once again, Savitar has a brief cameo talking about DeVoe's cerebral inhibitor. He neglected to mention in the flashback if it actually worked.
- Ralph warns Izzy about using the S.T.A.R. Labs elevator since killer robots tend to emerge from there.
- Convicted by Public Opinion: Discussed by Captain Singh who tells Barry that in 2018, people only care about accusations and not evidence.
- Deader than Dead: Barry seems to believe that this is the fate of the bus metas that DeVoe either bodyjacks or powerjacks, but we don't yet know if this is actually the case. However, the fact that the bodies DeVoe steals eventually wear out when his mind is in them lends some credence to this theory.
- Despair Event Horizon: Ralph hits it hard as he watches DeVoe steal Izzy's body and he's helpless to stop it. Fortunately, with a show of support from Barry, the loss of Izzy soon strengthens Ralph's resolve to stop DeVoe.
- Dull Eyes of Unhappiness: DeVoe-as-Becky has these.
- "Eureka!" Moment: When Harry reveals he built a "cerebral inhibitor", Barry and Iris light up as that's exactly what Savitar told them they needed to stop DeVoe.
- Exact Words: Cisco and Harry lampshade how Savitar had said the cerebral inhibitor had been "built to use against DeVoe." He never said anything about it actually working.
- Fair-Weather Friend: 99% of the CCPD sans Joe and Singh to Barry. Despite his acquittal, not everyone is convinced of his innocence and they believe he shouldn't be given his job back. Indeed when he walks back into the precinct instead of receiving a hero's welcome, he's given Disapproving Looks.
- Forced to Watch: Separated with the same forcefield the Thinker used to trap the Flash earlier in the season, Ralph and Barry could do nothing but watch as he bodyjacks Izzy.
- Foreshadowing: The first lyric we hear Izzy singing is "got a real good feeling something bad's about to happen."
- Forgot About His Powers: When Izzy faces DeVoe in the episode's climax, her instrument breaks, leaving her helpless. Except she already managed to fend off DeVoe without an instrument earlier. Perhaps she thought another bit of bad luck would stop her, but she doesn't even try.
- From Bad to Worse: During their first battle with DeVoe, Izzy's powers seem to be the only thing that can stand a chance against him due to his multitude of bus meta powers. By the end of the episode not only is she out of commission, but he's added her powerset to himself as well after bodyjacking her.
- Freeze-Frame Bonus: Several on Izzy's website:
- One of her postings is an update on the status of her Blue Valley concert, citing that it's been cancelled because of "some sorta' starfish situation", a Continuity Nod to "Therefore I Am", when Wally referenced fighting a giant starfish from outer space (presumably Starro from the comics).
- She also has concerts scheduled in Keystone City, Star City, Coast City and Bludhaven.
- Gender Flip: In the comics, the Fiddler has long been an elderly male, but here is an attractive young woman. However there was a female fiddler called Virtuoso.
- Good Thing You Can Heal: It's obvious DeVoe doesn't want to kill Barry just yet, which means him giving Barry a brain aneurysm relies on a speedster's Healing Factor.
- It's Personal: It becomes this for Ralph after DeVoe steals Izzy's body.
- Mind Rape: DeVoe used Brainstorm's Telepathy to induce a brain aneurysm to the Flash.
- My Greatest Second Chance: Barry couldn't stop DeVoe from stealing the other metas' powers and lives, so he's not going to let that happen to Izzy. Or not.
- My Greatest Failure: Ralph was borderline catatonic when he found himself helpless to save Izzy. He insists It's Personal with DeVoe from here on out.
- Mythology Gag: Barry slaps Harry's new invention on DeVoe's forehead and it lights up its three nodes in an inverted triangle, coincidentally just like the unofficial insignia of Brainiac.
- O.O.C. Is Serious Business: When Captain Singh addresses Barry by his first name, instead of just calling him "Allen" like always you know things are serious.
- Poke in the Third Eye: Vibing where Izzy is, confronting DeVoe, Cisco is thrown back after he turns around to look at Cisco and tells him "Nobody likes a Peeping Tom, Mr. Ramon."
- Possession Burnout: This is finally revealed to be the reason why the Thinker keeps stealing bodies; each one inherits the ALS his first one had and he can't stay in any one body for too long.
- Prophecy Twist: Savitar mentioned using the cerebral inhibitor against DeVoe, so Barry is excited when Harry comes up with one. When it fails, Cisco points out that Savitar didn't say anything about it working.
- The Reveal:
- Why did DeVoe steal Hazard's body? It's because Dominic's body was decaying and Hazard's is already; all the accumulated dark matter is taking its toll on him no matter what body he's in. So he's jumping from body to body to stave off the inevitable.
- Up until now, DeVoe's hideout was implied to be a secret chamber hidden in the basement of his house, but Cisco realizes that it's actually a Pocket Dimension.
- Ship Tease: It is quite obvious that Ralph has a crush on Izzy. After her body gets taken over by DeVoe in the end, he suffers from a massive Heroic BSoD.
- Shout-Out:
- When Cisco mentions soundwaves during the explaination of Izzy's powers, Ralph comments that Soundwave would be a great nickname. Cisco retorts it's already taken by a character from Transformers.
- When Ralph gives Barry his own personal PI card, Barry responds with "You like me! You really like me!"
- When Caitlin hands Izzy her fiddle to use during training, Izzy is confused as to how a fiddle is supposed to allow her to fight, unless the fight involves dueling The Devil, referencing "The Devil Went Down to Georgia" by Charlie Daniels.
- The album Izzy is promoting is called "Bad Girl Rising", a reference to "Bad Moon Rising" by Creedence Clearwater Revival.
- Skewed Priorities: Izzy rants to Team Flash about the sacrifices she had to make advance her music career and refuses to put it on hold despite the attempt made on her life.
- Stating the Simple Solution: The gang are racking their brains trying to figure out how to find Izzy. When Ralph asks if any of them has bothered to check her website, he rolls his eyes seeing their looks of surprise.
- Villain with Good Publicity: During the news broadcast Captain Singh is watching just before meeting Barry, it is said Wolfe died a hero while he actually intended to sell metahumans to an exploitative woman.
- The Worf Barrage: The Cerebral Inhibitor does nothing to DeVoe due to Kilg%re's powers disabling it.
- You Have to Believe Me!: Barry has to convince Subject 9 that she's being pursued by DeVoe.
