Every writer has times when their story hits a lull, even a small one. To remedy this, some will add a character or kill one off. Some will start an argument or weave in a new subplot. All of these are valid and great ways to keep a reader reading.
Me? I have people throw each other into things. Walls. Floors. Ship masts. Anything solid will do.
And you know what? I'm good with that. I can be the writer with violently outbursting characters. :)
