I could see them doing a stillbirth storyline with Cyril and Lucille too. Maybe Lucille will have a miscarriage scare which turns out to be false and everyone thinks it'll be smooth sailing. Then it's discovered several months later that the baby has died and it's the idea that she will have to carry it until it's born knowing that she is giving birth to a dead baby.
Cripes, no. That would be too awful.
