I was wondering what the thoughts are in regards to maintaining the integrity of a character that changes. How should the author establish new obstacles for the protagonist that has fulfilled the challenges of the theme? At which point do changes become too drastic and deviate from the primary story? In my opinion, it would almost seem cheap to have something come along and destroy all that had been recently realized. One plausible method I thought of was slowing the character growth. However, I would like to find ways that address the "cold sequels" -- in order to avoid, say, a Star Wars prequel effect.
