It's like a sudden cold front has moved in.
I sit at the keyboard and look at them, waiting for them to act, and they just sit there staring back at me, their half-accusatory frowns telling me that they've decided they don't want to cooperate anymore.
I'm TRYING to give you a happy ending, I say.
Well we're not happy right now, are we, they retort.
But you WILL be, I promise! In just five short days, it will be happily ever after!
Oh, really? And how do you plan to get us there from here?
I... I'm not ENTIRELY sure. I was sort of hoping you could help me out.
Right. As if we're going to do the dirty work for you. Frankly, we're tired of bickering. Nope, we're going to sit right here and WAIT until you show us the door out.
And so we sit. And stare. And sit. And stare...
Characters can be like little children. Sometimes they need a good boot in the butt. I don't mean you stare back and yell at them because that'll only make it worse. I mean add some inciting action. It doesn't have to be a humongous plot point. If I had control of these characters, this is how our conversation would go:
"Okay, let's get moving."
Character A, "But I don't wanna."
"CA's right. I mean, geeze," Character B said with a shake of his sorry head, "You've been dragging us through hell. Really, what do you expect?"
"I expect you to get to the happy ending whether I know where it is or not," I said. Reaching into my pocket, I felt a short, slender object whose only distinguishing feature was a small button.
Character A and B shook their heads and started a staring contest with me.
I smiled and pressed the button.
That's when the fire-breathing tiger jumped out of a rip in the space-time continuum.
I said, "Let's get moving!"
And, with grumbles and curses abound, the two characters ran after me to pursue Happily Ever After because really, what do you expect two characters to do? Stand there and get eaten?
I think in some cases you're just going to have to stand back and let your characters hang out in freeze-time. If your characters are tired, your brain is tired and vice versa. Also, I notice when my characters are being unruly, I'm either driving them to a snarly plot point (which I may or may not be able to traverse,) or their personalities are starting to change from my original vision.
Case in point: I had a character named Nathan Arunuki. I designed him to be your run-of-the-mill, homeless asshole. He was mean and tough. As he progressed through the plot, he became more and more difficult to write. It got especially bad during times where he had to take definitive action.
Then, one day, he blurted out, in front of me and all the other characters: "I'm afraid." Simple as that. I'd never imagined Nathan being afraid. Afterwards, he was easy to write again. He'd had his say and could move on, take responsibility and, ultimately, die for it.
Take a look at how your characters are developing and what they're trying to say. Maybe they're trying to hint that the happy ending planted in your subconscious is not what they had in mind. Maybe one of them wants to spring a secret. Who knows? You do, of course! Or you will, just as soon as you strangle it from those suckers. (Especially when it comes to secrets. Fictional characters are as reticent about them as real life people.)
