Just a precision since you seems to maybe be thinking otherwise:
The write in will use the spectre if Glynda accepts the story, not the stranger.
Which means that *the full story* in it is not really the full story, it's one of the five.
Telling the story with the stranger is telling the actual truth, all others are lies by omission.
Plus, now that I slept on it, the write-in is very misleading about how it describes the Spectre route.
In fact,
@Bond674, sorry to ask after I already accepted the write-in: Are you sure you wanted to put the Spectre as the route for the *long and fraught with horror version*? Because the Spectre isn't really long, nor fraught with horror, not for the Princess.
It's just: you died, you came back as a ghost, your love accepted to be possessed and you left the cabin together. The Thorn is both longer and actually contains more betrayal and psychological horror.
But mostly, if Glynda accepts, why not just go back to the first choice and tell the Stranger?
It is, after all, the one that is the truth, all other individual ones are not the full story.
Glynda confronted you on the basis that some parts of the past you told her where contradicting each other, telling the Spectre would make things worse, since it is a direct contradiction to the Thorn you already told to her partially when with Blake.
So, hmm, to everyone, are you sure the write-in as is (with a story that directly contradicts what you said earlier in the Spectre) is a good idea?
