I’m terrible at writing and this may be borderline fanfiction/soap opera, but maybe someone can put my thoughts into a short story.
So here’s the gist: Shallan/Radiant is happily married to Adolin, but Veil isn’t. Veil still swoons and crushes on Kaladin whenever he’s around. Veil and Kaladin have an affair. Shallan, feeling extremely guilty confesses to Adolin what happened. Adolin, being Adolin is extremely hurt and angry at first, but still loves Shallan, so he forgives her. But then, bum bum BUM, Shallan is pregnant. Adolin says that no matter what, whether the child is biologically his or Kaladin’s, he will raise it as his own. But then the twist, the baby is born without a spec of blond hair, and one light eye, and one dark eye.
If someone wants to run with this, feel free!
