Someone had to die today. One of my characters did not make it through the story. To heaven, perhaps, but not through the story.
I cried. A spit and tissue paper person died, and I bawled like a baby.
I can say, “The muses did it.” Ultimately, though, I know it was me who typed the words. I will take responsibility for it.
As hard as it is, sometimes it needs doing. The need may creep up or it may shine like a lighthouse drawing you in. When it needs doing for the story, you just have to do it. You can send the departed character to heaven if you want, though, don’t put that in the story unless it is relevant.
