In S5 of the flash we were introduced Nora West-Allen. The daughter of Barry and Iris.

She was technically introduced in S4 but had a more prominent role in S5.

Her S5 storyline was so cheesy and cringey and they wrote her to basically act like a 5 year old having a tantrum even though she was technically meant to be an adult.

Nora was also annoying in S5 too.

I liked Nora, but her storyline was weak.

Nora also introduced not only Godspeed for the first time but also Cicada I and II.

For Nora I would have this:

Her storyline be based more around them and even her brother. Instead of being back to just run with the flash and meet her dad while also being at a chip.

I would also have it that Nora had more of a reason to comeback to the past too. I would have had it that Nora was in the past looking for her twin brother Bart who went missing to catch Cicada the villian Barry never got, and along the way Nora meets Godspeed who ultimately does kill Jay but in front of her and even threatens her that he will Bart.

Instead of Leia I would have introduced Bart, but in that timeline post Crisis as Nora's twin brother who works for the Citizen with Iris. Because if the show was always going to introduce Bart later on in tje show I.e S7 like they did, I would introduced him in S5 with Nora instead of Leia and I would have had it that he went missing trying to catch Cicada, and live up to his dad, and his dad's name of the flash, and what better way to do that than going after and catching the villian the flash never caught in the past, but I would also have Bart go missing with trying to catch Cicada and make it that Nora is looking for him.

And I would have also had Bart be the future Godspeed, after killing Cicada, as he would have had that thrill and Godspeed would have been more connected to Nora and the future and also the synopsis part of S7 with the villian trying to break up West-Allen, and the hero not only being connected to the flash but also Barry, and West-Allen together.

I would have had S5 be more based on the legacy and the future. As we saw Cicada II being the future Grace and having a connection with Nora. It should have been more deeper and connected to the theme of S5 which was legacy and future and even family.

And I would also have Nora write to Iris instead of Thawne and have her use the time sphere instead of her speed.
