Ever since people in this thread have posted about the lack of locks, I’ve noticed how often that happens. 
That said, on the other hand, it DID let Deus Ex Iris come in at exactly the right time to bonk Peek-A-Boo on the head.
(And the resemblance between the comic book version of Peek-a-boo and the TV show one is amazing. Most of the other characters aren’t bad matches, but damn…they got her perfect.)
Also: Why would Cisco name Lisa “The Golden Glider”? She doesn’t glide. Her original version (back in the late '70s) was a figure skater who went nutz when her boyfriend (the Top) died and she wanted to murder Iris so Flash would suffer like she did. Great character, great motivation. And since she had flying, ice-slide generating skates, the name fit. Here? You might as well call her “Goldface”. It would make more sense.
Finally–it occurs to me that we’re not going to see the big confrontation between Barry and Wells/Thawn (the current guy). Wells/Thawn is locked up*. Barry’s gonna use the Flux-Capacitor battery (which is obviously charged by the Speed Force) and/or the accelerator (which is on, and powered up, Wells/Thawn’s capture not withstanding) to go back in the past to save mom…and run in to Thawn/pre-Wells.
I’m guessing this is a set-up by Thawn/Wells. By accidentally snuffing Nora, Thawn/pre-Wells wiped out his own future (possibly the Flashpoint future?) and so Thawn/Wells has been making Barry better so that when, from Barry’s POV, he first goes into the past, he can stop the Pre-Wells Thawn, save Nora and restore Thawn’s future (that what was what all the “I can’t go home again” whining was about, and would explain why, if Thawn is faster than Barry, why Thawn doesn’t just run home.
So the timeline looks like this:
[ol]
[li]Original 25th Century/Flashpoint Future (as a guess) Thawn/no-Wells goes into the past for reasons. (best guess: Thawn/no-Wells wants to emotionally cripple Barry by murdering mom? I dunno.)[/li][li]Original 2004-ish: Thawn/no-Wells appears in the past. Barry from 2015 appears soon after. [/li][li]Altered 2004-ish: Thawn/no-Wells beats a Barry who Thawn (any version) hasn’t trained and murders Nora. Oops. Thawn’s 25 Century evaporates.[/li][li]Altered 2005-ish: Thawn/no-Wells tries to get home, but home isn’t there. He figures out that he’s erased his future and becomes Thawn/Wells.[/li][li]Altered 2005-2014: Thawn/Wells does everything he can to make sure Barry is in a position to become an incredibly well-trained Flash so that when Barry goes back to 2004, Barry will win, thus restoring Thawn’s original future. (Possibly the Crisis doesn’t happen in Thawn’s future?)[/li][li]Altered 2015: The episode we just saw (“Rogue Air”)[/li][li]Altered 2015: Barry, after “capturing” Thawn/Wells decides to go into the past. [/li][li]Original 2004-ish" Barry is surprised to find a Thawn/No-Wells who’s never encountered the Flash before hanging around. Since Flash has been trained to fight a 10 year more experienced Thawn, Barry trounces Thawn/No-Wells and saves Mommy Nora. Oops. But we’re back to the “original” timeline where Thawn’s future exists again.[/li][li]Original 2005-ish: With Thawn/No-Wells captured, Wells (sans Thawn) and his girlfriend have a very nice drive home from their day at the beach. Nothing happens at all (salvaging the popular character of Wells).[/li][li]Original 2015: No Thawn/Wells means no “accidental” particle accelerator explosion means “no Flash” means “Thawn’s 25th Century is back” (or the particle accelerator explodes anyway, but Barry isn’t trained by Thawn/Wells and without the training and without the motivation of mommy’s murder, Barry is a half-assed slacker-Flash) [/li][li]Original 2015, first episode next season: Barry returns from his triumphant victory in 2005 to find out that Central City makes Gotham look like the “Small World” ride at Disneyworld and is part of bigger crapsack world. Barry has to undo, as best he can, what he did and let Nora die. (say 3-4 episodes of S2.)[/li][/ol]
Feel free to point out this post to me next week when it turns out I’m completely wrong and PALAMe.
