I'm currently rereading Children of Dune, but I have previously read through God Emporer. I came across this passage that stuck out to me and raised a few questions.
This is while Leto II slips into Paul's memories and Ghanima into Chani's and they are speaking to each other.
"Maud'Dib, the hero, must be destroyed utterly," he said. "Otherwise this child cannot bring us back from chaos."
"The Golden Path," she said. "It is not a good vision."
"It's the only possible vision."
"Alia has failed, then..."
"Utterly. You see the record of it."
"Your mother has returned too late." She nodded, and it was Chani's wise expression on the childish face of Ghanima. "Could there not be another vision? Perhaps if--"
I know that Alia is now possessed but they're talking as if there was some action she failed to take prior which would have created a better option than the Golden Path. They also mention Jessica's late return sending them down this path. I'm trying to figure out what Alia and Jessica's earlier return would have changed which would have opened better options for Leto II.
Every time I think I understand the Golden Path, I find some post on here that makes me question how much I actually understand so don't be afraid to over explain.
