As you all know, I am so mad and disappointed by this whole Bart situation.
I came up with a solution on what the writers should of done and how they should of introduced Bart as the grandson and NOT the son.
First of all, Jenna was a wasted character. That whole storyline of Cecile getting pregnant back in S4 and Joe and Cecile being parents again was so stupid and waisted. Joe and Cecile were/are too old to be parents to a baby. And since then, they've hardly even showed Jenna. It was just stupid and a waste of time.
That is why Iris should of been pregnant with Nora instead of Cecile. It would of created a better storyline and it would of worked out perfectly.
In the S4 finale, Iris should of given birth to Nora, then future Nora shows up at their doorstep where the episode finishes.
Then everything that took place in S5, remains the same. The only thing is that Barry and Iris will have a baby. While trying to be parents and raise their baby, they will be helping future Nora. Then instead of Nora getting erased from existance in the S5 finale, she goes back to the future safely.
And the S6 events happen the same. Nora would've been a toddler. Probably around 3 or 4 years old.
And finally in S7, she would of been around 5, 6,7 or 8 years old. Instead of Bart and Nora coming in S7E5, it would of been the grand kds. Bart and Jenny would of been the ones to come. Barry and Iris's grandkids would of came and the events that happened in S7 would remain the same as well.
That is what they should of done instead on the flash. But the stupid writers messed up.
It makes sense, and it would of gone so well. And I think the flash would of been even better if they had done this. This is my opinion.
