Perspective Reversal

Earlier in a story, opinion/assumption X is associated with Alice, and opinion/assumption Y is associated with Bob. Later in the story, Y is associated with Alice and X is associated with Bob instead.

Note that "perspective" is not literally a physical perspective but is used to refer to either opinions or assumptions; this can apply to either.

May in some cases result in an Ironic Echo. See also Hourglass Plot.

By the end of the game, Cheren has reached a roadblock and is questioning if he even has the personality to be a champion, while Bianca comes to terms with her father, who didn't want her going into the dangerous world on her own, and has decided her path for her future, assisting Professor Juniper in the lab.
 * It's subtle, but this a major theme in Final Fantasy X and its sequel, Final Fantasy X-2. In the first game, Tidus (the protagonist) is a selfish, wangsty teen who is more concerned with returning home than the imminent destruction of Spira. It isn't until he learns that his Love Interest (Yuna) will have to sacrifice herself to defeat Sin that he starts to undergo Character Development and refuses to let Yuna sacrifice herself to save the world. There's a conversation roughly a third of the way through the game which highlights their different philosophies, in which Tidus questions whether sacrificing your life, even when the Big Bad is sure to come back is worth it and Yuna disagrees and says she feels any sacrifice is worth bringing just a little happiness to the world. In the end, Tidus has to make a Heroic Sacrifice himself in order to destroy Sin and break the Vicious Cycle, devastating Yuna, who had been prepared to sacrifice herself, but not her loved ones. Then, in the sequel, Yuna is a Heartbroken Badass Action Girl whose perspectives on sacrifice have completely changed. When another character offers to sacrifice himself in order to defeat the new Big Bad, Yuna shoots his plan down immediately, stating how much she's grown to hate having to "lose in order to win". To make this juxtaposition even more poignant, Yuna's outfit throughout the second game is a direct homage to her dead love.
