That moment when you realise an innocuous detail you included in your WIP actually holds the key to the whole plot.
Honestly one of the most humbling feelings, because it’s the moment you realize you were never in charge of the story in the first place, ‘cause you thought it was this little nothing detail but now it’s absolutely critical and you wanna take credit for planning that far ahead but in reality you were just plunking along and everything suddenly fell together without your help at all.
