Question: how are all the conjuring and annabelle connected?
Answer: The Conjuring contains what's essentially a terrifying Annabelle short film, so it's no surprise to see how this evil doll quickly became a fan favorite. The Conjuring explains how the Warrens come in possession of the Annabelle doll, but Annabelle sets out to show some of the doll's carnage before she gets locked up.
