Since I'm doing my best to become an author and I get interviewed similar to Kishi this is probably how it would be:
Interviewer: So why do you write characters that show progression and growth and how can you compare that to other authors?
Me: Well one of the things about creating a character is to show them struggle, help them evolve from how they start off in the beginning of the story. Not to be point fingers, but that is something I've noticed with some authors where they'll show growth and progression and suddenly getting dropped by the end of the story like it doesn't matter. They think because it's a fictional world that they deviate from reality and have the characters do what they want despite what those characters went through. That seems to something these authors don't really take into consideration, you need to show see these things in your characters because it'll make them relatable and people can connect with them.
That's probably how things would go down on my end.
