* CriticalResearchFailure: Cisco mentions that Caitlin has "Two doctorates and a [=PhD=]." This is a bit odd, as a "doctorate" and a "[=PhD=]" are essentially [[DepartmentOfRedundancyDepartment two terms for the same degree]].

* SpecialEffectsFailure: The scene where Barry rescues Iris from Samuriod looks very much like it came from a video game, rather than a tv show.

* TheyWastedAPerfectlyGoodPlot: Barry's departure left room for viewers to fully see how the team could tackle evil in Central City in his absence. However, since the main crux of the episode is bringing back Barry, this isn't explored fully in detail, relegated only in the six month TimeSkip between Seasons 3 and 4.
** Then again, it was probably [[StatusQuoIsGod never realistic to expect the show's lead to be gone for very long]]. And the "fighting crime without the Flash" angle was sort of already explored late in Season 2 when Barry (temporarily) lost his powers.
** When Barry was PutOnTheBus at the end of Season 3, many fans thought it was because of the rule that CW wasn't allowed to use any heroes in the Franchise/DCExtendedUniverse, with the Flash joining the Justice League. It was assumed that it would be Wally's turn to shine.

* CounterpartComparison: The premiere of the fourth season of a DC/CW show where the hero returns from another dimension where he was being held since the end of last season, not entirely by his own choice and by an entity resembling his parent, albeit with a power upgrade and not quite himself until the end of the episode.

* MemeticMutation: Cisco's translation algorithm decoding Barry's demented scribblings as "This house is bitchin'" was eagerly seized upon by the fandom.

* {{Foreshadowing}}: Possibly with Barry's rambling line "We're gonna need more diapers." This could possibly herald Iris getting pregnant with the comics' Tornado Twins, Don and Dawn Allen.

* OneSceneWonder: The Thinker makes quite the impression for only a few minutes of screen time.

* AssPull: Barry snapping back to normal when Iris is kidnapped. It's so cliche and reaks of DeusExMachina, since nothing in the episode foreshadows it. [[FanDumb It’s almost as if theres more to this than it seems]].
