History Recap / TheFlash2014S6E14DeathOfTheSpeedForce

* VillainDecay: [[Recap/TheFlash2014S1E22RogueAir Previously on]] ''[[Series/TheFlash2014 The Flash]]'', a depowered Thawne was able to hold his own against, Barry, Oliver, and Firestorm all at once. In this episode, he fights Cisco alone and the two seem fairly evenly matched, despite Cisco emphatically ''not'' being a BadassNormal.

* VillainDecay: [[Recap/TheFlash2014S1E22RogueAir Previously on ''The Flash'']], a depowered Thawne was able to hold his own against, Barry, Oliver, and Firestorm all at once. In this episode, he fights Cisco alone and the two seem fairly evenly matched, despite Cisco emphatically ''not'' being a BadassNormal.

* CardCarryingVillain: Frida Novikov, who [[RedemptionRejection rejects]] stopping her rampage when Barry begs her to and tells him that she doesn't have to do it, but wants to.

** Cisco believes all doppelgängers that landed on Earth Prime to be dead from the same affliction that affected Beth and Alice on ''[[Series/Batwoman2019 Batwoman]]''.

** Similarly, while Cisco is (as the fight choreography shows) not a very effective fighter, Eobard was able to go toe-to-toe with ''Oliver''. If not for Cecile, he would've just killed Cisco the old-fashioned way.

* TheBusCameBack: Wally West (Creator/KeiynanLonsdale) appears for the first time since "[[Recap/TheFlash2014S5E1Nora Nora]]", and Cisco Ramon (Carlos Valdes) returns after three episodes. Thawne also comes back by [[DemonicPossession possessing Nash]].

** Thawne, as usual, determined to murder all of Barry's loved ones, including [[LikeASonToMe Cisco.]]

* RealityEnsues: Even without powers, Thawne (possessing Nash) and Cisco are still seasoned fighters, and get into a real brawl.

* RealityEnsues: Even without powers, Thawne (possessing Nash) and Cisco are still seasoned fighters, and get into a real brawl. It would have lasted longer if it weren't for Cecile's intervention.

* ShoutOut: Barry channels his inner [[Franchise/StarWars Yoda]] when Wally tells him about the disturbance in the Speed Force.

** Cisco is alone with Thawne possessing Nash's body.

* DiabolusExNihilo: Somewhat with Thawne, who all of a sudden unexpectedly returns as a major threat for the team to deal with while they are already in the midst of their ongoing troubles with Black Hole, Mirror!Iris and Eva, and whatever the hell Sue is up to. However, this is a bit [[DownplayedTrope downplayed]] in that Thawne was at least ''seemingly'' foreshadowed by the alternate versions of Wells that Nash had been seeing for a few weeks.

* ChekhovsGun: Cisco's camera and the hoto stored in it are important later on when Kamilla discovers something off about "Iris".

* WhamEpisode: Barry and Wally are depowered when the Speed Force dies, Thawne possesses Nash, and Mirror Iris banishes Kamilla.

* TimedMission: As Thawne notes in the end, the death of the Speed Force means that Barry will gradually lose his speed permanently in a few weeks' time; [[FromBadToWorse however]], since Thawne's power comes from his ''Negative'' Speed Force, he isn't affected, leaving Team Flash completely defenseless against him. They need to create a new Speed Force, and fast.

* NotHisSled: With all the inspiration from [[ComicBook/TheFlashRebirth the ''Rebirth'' line]] that this season has taken, comic fans may be inclined to think the reappearance of Turtle would introduce the other Forces as what's killing the Speed Force. They end up having nothing to do with it in the end, instead being the result of Crisis.

** Cisco believes all doppelgängers that landed on Earth Prime to be dead from the same affliction that affected Beth and Alice on ''[[Series/Batwoman2019 Batwoman]]''. Which at the same time is a ContinuitySnarl as ''[[Series/Supergirl2015 Supergirl]]'' didn't have that problem.

* FailedAttemptAtDrama: Cisco dramatically names the VillainOfTheWeek as "Turtle 2"...and Barry stares at him for a moment before stating that he was waiting for Cisco to announce a better name. The background music even grinds to a halt.

* GlamourFailure: A digital photograph reveals Mirror Iris' true nature, [[{{Foreshadowing}} explaining]] her abhorrence to having her picture taken earlier.

* FailedAttemptAtDrama: Cisco dramatically names the VillainOfTheWeek as "Turtle 2.0"...and Barry stares at him for a moment before stating that he was waiting for Cisco to announce a better name. The background music even grinds to a halt.

* AloneWithThePsycho: Kamilla, upon realizing that something is wrong with "Iris", realizes that she is completely alone with her and promptly gets shot by the mirror gun.

* RayOfHopeEnding: The Speed Force is gone, Mirror Iris shot Kamilla, Thawne is possessing Nash and the team has a limited time before Thawne kills them with his powers. However, Barry still can find a way to restore the Speed Force and to save Nash.

* TookALevelInJerkass: Thawne doesn't even bother putting up a facade anymore, he is just straight-up planning to murder Barry and everybody he ever knew and loved.

* MyGodWhatHaveIDone: Barry is remorseful about doing a Reverse Flash" on the Speed Force and accidentally killing it by taking in the Spectre's energy during Crisis.

* TheReveal: It turns out the "ghosts" of dead Wellses Nash has been seeing
were literal, and the one "Wells" that actually isn't, Eobard Thawne, pulled a GrandTheftMe.

* BackForTheDead: The Speed Force as Nora Allen returns and Barry sees her die.

* MyGodWhatHaveIDone: Barry is remorseful about doing a "Reverse Flash" on the Speed Force and accidentally killing it by taking in the Spectre's energy during Crisis.

* RapidAging: How Turtle 2.0 kills her victims, as shown with poor Maria. She traps them in time bubbles that rapidly speed up time for them.

* WhamEpisode: Barry and Wally are depowered when the Speed Force dies, Thawne possesses Nash, and Mirror Iris seemingly murders Kamilla.

* BecomingTheMask: The Speed Force, which has mostly operated on BlueAndOrangeMorality, tells Barry that it grew to love him on its death bed like Nora allen would have.

* LetMeTellYouAStory: Wally tells Barry a buddhist story while apologizing to him.

-->''"You were trying to save the universe. Any hero would have made that call. (deep breath) '''I''' would have made that call"''.

* YouDidTheRightThing: As Barry bemoans that his use of the Speed Force to bring back the multiverse is what has ultimately killed it, both Wally & the Speed Force itself assure him that he made the right call.
