DiscardedYKTTW 3-Defining Moment YKTTW Discussion
This is when a side character, or a main one who has thus far proved to be a Flat Character, reveals or dynamically develops a new facet that makes them a Rounded Character. Faced with a situation where they would act predictably if they were flat, they surprise audiences (and other characters) by turning over a new leaf. This isn't Character Derailment or an Out-of-Character Moment, it usually signals a dramatic shift in a character's story arc. For characters who have so far been extras, it may bump them up to Mauve Shirt.
