A few months back when I last delved deep into my fantasy world (after a long hiatus), it took a curious turn.
An idea came to me, a plot twist which would cause my protagonist great shock and agony (intense emotions; yay), and could also explain some parts of the story which didn't have good explanations yet. It was a dangerous story idea, one which threatened to sabotage the whole fantasy, so I didn't take it very seriously at the time, beyond relishing the momentary rush of agony/strong emotions.
Since then however, that latest plot twist has been lurking... possibly causing me to avoid delving into the fantasy again, because I don't know how to recover from that twist of events which leaves my protagonist bereft of ever truly having had a soulmate or significant other.
Once a strong idea manifests, it is hard to simply say, "No, no. Let's ignore that idea and pretend it never really happened in the actual story."
I suppose it's not without precedence. There have been seemingly insurmountable plot developments before. But each time, the story changes course; changes flavor; never fully returns to its previous state.
