Character-To-Author Indignation

So I'm writing on OWOR, and I get to a part that needs to be changed. This is not out of the ordinary. I start changing it, and Heaven does something that is totally unexpected, sundering the plot.
Hadri is about to go off and kill some people. Heaven jumps on the bike with him, trying to get him not to go. I am dumbfounded, and I set my Writerly skills in motion to get her off the bike.
It doesn't work.
"Heaven, get off the bike." I say.
"No." she says indignantly.
"What do you mean, no?"
"No."
"I'm the Author, you're the character. What I say goes."
"Not gonna happen."
I throw my hands up in frustration and say, "Hadri, get her off the bike."
"How?" he says, throwing his hands up questioningly.
"Caster, get her off the bike," I say.
"She is Woman and she is Roaring, I'm not touching that."
"Damnit, somebody get her off the bike."
So I set my god-like writerly skills in motion again, this time with Hadri's help, and we eventually get Heaven off the bike, so the plot can go on.

What this says to me is all three characters are whole people. I can no more set things in motion that they wouldn't do as they could control my life. This is a good thing, a very good thing.

Needless to say, I'm having a lot of fun with this project.
