Sometimes we have characters in our novels that just aren’t doing anything to move the plot along.
Perhaps we like this character and so we mold and shape him. We give him the correct lines, witty banter. We even make him wowzers handsome.
Here’s the truth of it.
That guy’s gotta go.
If he ain’t pulling his weight, no matter how dynamic he is, you gotta get rid of him.
Look at the earlier writing prompt where you drew a circle, with your main character in the middle. All those lines lead to characters in the novel. Are they all important? Can you do without a few? Are there any people not doing their duty?
Every person who shows up in a book must DO something. No talking heads. No mannequins (unless you are Richard Peck writing SECRETS OF THE SHOPPING MALL. Mannequins WERE used in that story.)
So, get rid of all those who are weighing down the story.
And if they are super cool? Use them in another book.
