Why is everyone so mad he's gay? So what if they have to modify the story. I think it's a brave artful decision to make. Susan can simply be a man and it's all fixed. Maybe in the african american kingdom of gilead everyone is gay and they all adopt babies? So maybe Roland was adopted into the house of gilead. Nothing wrong with gay adopted black babies so everyone just chill or i will report you.
Oh, I'm sorry but it's prejudice for you to assume they aren't american because they are black. Gilead may in fact exist within geographical america or post-america. We will see when we hear his accent.
Even though you're being an egotistical child about all of this, you're actually correct. ANYTHING can technically happen, because there are endless multiverses, and the one Roland is involved in has been repeating and changing for an incredibly long time.
Go join a book club and try to understand things a bit better.
All this talk about things changing etc each "cycle" is laughable. Read the afterword of the last book. King coppee out because he didn't know how to end the series. The idea was of the collective unconscious using king as an antenna to channel these stories like all other huge writers and musicians and poets. That's it. Not so races can change and plot pieces can really change. Lmao.
