We love them all, even the villains. How could you not? You created them, didn’t you?
And yet, didn’t one just ‘come to mind’ in an idle moment? And she was a perfect fit for a cameo role. And later on she was just right for a change of role.
Who cares, as long as it works and the story is improved. Whether ’tis an aberration of the mind or the muse whispering your ear, accept the gift.
