I think the scripting on this is a bit random. I'm going through a phase where I think of a general plot for the episode, then draw out some panels, and only then pin down the final dialogue. At least, that's what I tell myself. What's really happening is that I forget to note down the words in my head and forget them between then and when I come to letter it, so I have to come up with something new all over again.
