I don't understand why Flashpoint had to happen on Earth-Prime.
Why does Henry Allen have to die? Oliver could've brought him back like he did Moira Queen.
I know some of you say that Henry had to die bc that's what triggers Barry to create Flashpoint, but, bear with me here, the whole point of Flashpoint is that Barry altered the natural order of things and Nora had to be killed, right?
So why does Barry changing the timeline also had to happen (in Earth-Prime)?
