Also, I ran into a problem in that late in the book, a specific character has to do a specific action; the entire plot hinges on it. If I kill off a certain other character whom this pivotal character is very attached to (OK, I'm talking about Trajan Lear and Matt Driver, I don't think that's a spoiler) it makes his action easily understandable from a motivational standpoint. On the other hand, I have had a joke in mind since way back about the time I was writing Book 04 that requires that this other character be alive. So, do I want an emotional rationale that will make a certain pivotal action understandable even though it is out-of-character, or do I want to go for the joke.
Yeah, I'll go for the joke. What else would I do?
