I thought this episode of Flash was very good. I think it played all the right notes, though of course as with everything, you have to suspend a little disbelief.
For example--if Savitar was a time remnant created by Barry to stop Savitar, then Barry would simply have to not create time remnants to stop Savitar, and Savitar would be stopped.
The counterargument to that is that if Savitar is a time remnant, then stopping his creation would not stop this time remnant.
Of course then you have to question Savitar's comment about how Iris needs to die so Savitar could be born.
I liked how Savitar found out where Iris was, and that they did that scene with HR's guilt.
The characters could have been more creative in hiding Iris. I was saying that they should stash her on another Earth too, but what they should have done is told their team Earth 2, and gone to yet another Earth.
And then time traveled to the past on that Earth.
No one would know where they were.
Regarding the ARGUS subplot, which I liked, especially with Captain Cold, if only Barry had a close friend who was an alien, with access to future technology, that would likely have a power source that could help, and maybe Cisco could vibe them to her world, where Iris would have a protector that should be able to defeat Saivtar by herself.
But again, I can rationalize that by the fact that they were under a lot of stress and pressure and may not have thought of it.
And I just scrolled up, read the point about stashing Iris at ARGUS, and applauded.
Bottom line though, is that if I watch the episode without the nitpicking, and just enjoy the story, and buy into it, it was kind of awesome.
It also took some guts to kill Iris off in the penultimate episode. I'm sure I'm not alone in thinking that Barry would have found a way to save her.
To my knowledge, she is not leaving the show. So I will go with the idea that the ending of this episode will not stand. With that in mind, it makes killing Iris this week a very smart decision.
If you think about it, if Iris doesn't die like we saw, then when Barry comes to the future six months ago, he doesn't see Iris die, and doesn't go through everything to save her. By having Savitar succeed, the cycle is complete.
And now we are in the unknown. I'm really looking forward to the finale.
