I've written myself into a hole.
It's not a big hole. More a ditch, really. Shallow grave size at the most. I hope.
In the rough draft of my WIP I had a character do something I needed him to do. Fine. No problem. He did it and he didn't bitch about it. Much.
But now I'm in rewrites and I'm finding that he doesn't have a whole lot of reason for doing it. I need him to do it, because if he doesn't everything kind of falls apart. But he's looking at me and shrugging his shoulders and asking why.
The crux of the problem is that I don't know him as well as I need to. So now I'm spending a lot of time staring into space trying to figure him out because I don't have a strong enough reason for him to do it. It's good, and important and ultimately will make the whole thing work better. But it's still goddamn irritating.
How about you? What holes have you written yourself into? Accidentally killed off a character you needed twelve chapters later? Stick your protagonist into a terrible situation and find you have no way to get her out? How about destroying that one important clue in a house fire and realizing too late that to fix it you have to completely rethink the last half of the book? You know, the 420 pages you thought you were so brilliant.
