I'll be honest. I don't even know what character dynamics are. Is it when characters do something dynamic, like jumping off a cliff on a skateboard, or riding a shark to Brazil? Is it when characters interact with each other in a dynamic fashion?
Because my characters almost never ride a shark to Brazil, or interact together in a dynamic fashion. Take the scene I wrote last night, for example. My characters sat on a couch, trying not to watch steamy movies together because it felt kind of like watching a steamy movie with your Gran (the heroine is scared of wanting sex with the hero, cos he's a cat-person), so the heroine puts on a horror movie. Which scares the bejesus out of the hero, because he's hardly watched TV in ten years.
So I guess my hero isn't very dynamic. But I think there's some sort of dynamic going on in all of that. I think. Maybe. Is the dynamic that they really want to have sex, but are afraid of things? I dunno.
Because I think I'm kind of like Lisabet- I don't really plan these things out. My characters just kind of say stuff to me, and then they do things, and then I get worried about whether or not my hero is far too wet, because the movie Aliens scared him so much he had to hide under the heroine's butt.
But then, that's who he is. I can't imagine him being any other way. If he watches a horror movie, he gets scared. And though my heroine doesn't want to, she finds this behaviour very appealing in some way she can't fathom.
Maybe because I can't fathom it either. It just happens, okay? I've no idea why. I'd ask my brain, but it's too busy checking out Evan Lysacek's ass.
