I want some actual PLOT DEVELOPMENT, and we got it in spades this episode. So to immediately undo it, only to rehash the same "reveals" is not at all appealing. It's like when Smallville would do a big "reveal," only to then undo it and then drag out the ACTUAL reveal to a painful degree. Also I'm just tired of Iris being the ONLY one who DOESN'T know. It adds nothing of value to the show, there's not good reason for it (either in-universe or without).
What are you even talking about? Just because certain
events of last night's episode will technically be reversed and erased (Iris learning Barry's secret, Cisco's death, Caitlin seeing Wells disappear, the police captain's major injury), that doesn't mean that the plot hasn't developed further. In fact, the plot actually lurched forward in a major way for our main character and for us as viewers.
- Barry learned how Iris truly feels about him, which he will not have magically forgotten. That means no more complaining to Joe about how things are weird between them or that his confession of his feelings towards her was not mutual
- We've seen how the relationship between Barry and Iris is starting to get to Eddie, which has furthers the "ticking time bomb" element of Eddie turning on Barry and Iris somehow
- Barry is starting to questions Wells' motives and capabilities, based on what Iris told him about the investigation she and Mason Bridge have begun
- Mason told Barry that he has incriminating evidence about Wells in his computer, which only added to the doubts Barry was already having and increases the likelihood of the truth about Harrison Wells coming to light sooner than later (for all the major players)
- We now know the true identity of Wells - Eobard Thawne, a man trapped in this time and desperate to get back to his own
- Eobard Thawne finally described his endgame and confirmed what most suspected -- that he is pushing Barry to develop his powers because The Flash's speed is the key to Thawne returning home
- It was confirmed that Eddie Thawne is a descendant of Eobard's, which fuels the fire of what Eddie will eventually become
- Previously, we'd seen Wells go through great lengths to protect Barry's life and his secret identity, even going as far as murdering people to do so. Many had wondered whether or not Wells was truly evil or that his true intentions were to help Barry. We now know that Wells is only using Barry as a means to an end, he had actually intended to kill Barry
instead of Nora, and that he is willing to kill even his closest allies (like Cisco) to protect his own secret and make sure his endgame is completed
- Everything about the Wells/Thawne reveal enhances the "ticking time bomb" element of when EVERYONE will discover these secrets, and how Earth-shattering it will be for the core characters on this show
And finally, the biggest reveal of all is that BARRY ****ING TRAVELED BACK IN TIME (much sooner than he ever thought he would), an event that Team Flash will obviously learn about when Barry tells them what happened. This changes the status quo of the ENTIRE series now that Barry and his allies will know he has this ability, he will most likely do it again, and will almost certainly attempt to use this ability to save Nora Allen -- which will lead to another Earth-shattering event for this series.
We're in the first season of this show and none of the reveals or imminent events have been dragged out to a painful degree. It's called "build-up". You're comparing this first season of a show to Smallville, which dragged out reveals and status-quo changes for multiple seasons. There are not many episodes left of this season of The Flash. We KNOW that the truth about Wells will be revealed to everyone before season's end, which will be crazy, and if you're really that pissed that Iris won't remember or know that Barry is The Flash still, you should relax but it will happen for real sooner or later.
This episode was cool because it showed us the ramifications of certain events, gave us new information, and confirmed our suspicions about certain things...without these things actually happening yet.
