Ed Catmull is one of the founders of Pixar, and I really enjoyed his book, Creativity, Inc. about the history and inner workings of Pixar. I especially loved this insight he shared:

“The definition of superb animation is that each character on the screen makes you believe it is a thinking being.”

I think this is true for characters we experience on the page as well. Characters in a book come alive for us when all the characters seem to be thinking beings rather than just words on a page.

For the writer, knowing your characters’ backstories is critical for creating this illusion. You can probably think of a person in your life who made you scratch your head until you learned more of their story, right? My daughter once had a friend who was really talented at sports, but was extremely hard on herself even when it seemed to us like she’d played well. The reason why became very clear after interacting with her overly critical parents.

Just like how we have little light bulb moments with real people, we can create the same sensation with our characters too. Characters can make lots of odd or dangerous choices and still feel believable to the reader, but only if we’ve taken the time to develop a backstory that supports it. (It’s important to do this for ALL your characters, not just your main character!)

I’ve found it’s often easiest to work backward on these sorts of plot puzzles. Start by figuring out what weird, crazy thing you need to your character to do or want, and then go backward using the question, “Why?” to find pieces that can make it work.

When I started working on The Lost Girl of Astor Street, what I knew was that Piper’s best friend was missing, and Piper went looking for her.

But why would she do that? If my best friend went missing, I would certainly help the police as much as I felt ablebut my instinct would not be to start my own investigation. So I had to figure out why Piper felt this was a good idea. For Piper to come across as brave rather than stupid, her choices needed to feel logical to the reader.

I started brainstorming potential answers to the question, “Why?” Maybe she felt responsible for some reason. Maybe there was something Piper knew about her best friend that no one else knew. Maybe she didn’t trust the police. Maybe in general she didn’t trust people.

Many of the things on my list led me to ask another why. It’s important to keep following those backward until you can identify an origin. If Piper felt responsible, why? If she doesn’t trust people in general, why?

When I kept following my “why?” backward about Piper’s trust issues, I ultimately landed on her mother’s death. When Piper was 13, her mother got the flu. Everyone around her said she would be fine, but then her mother died. That would leave a girl with some trust issues!

So then if I had a scene where Piper was being told, “Don’t worry, I’m sure we’ll find your friend,” I could show Piper remembering being reassured that her mother would be fine . . . up until her mother died. Then Piper’s decisions about pursuing the case don’t seem so ridiculous, and my reader understands why Piper is making this decision. Piper then begins to feel like a thinking being.

And when you apply this intentionality to not just your main character but your other characters too, you end up with every character on the page feeling like a thinking being!

Do you know the “why?” behind the weird/bold/dangerous decisions your characters are making?
