Shrek the Third
The Evil Queen was first seen shooting pool at the Poison Apple, which she owned at the time. At first, she disliked Prince Charming, but she warmed up to him when he promised her and the other villains their own happily ever after.
The Evil Queen was last seen holding a dagger to Queen Lillian’s aka the Other Good Queen’s, throat, but after Arthur Pendragon convinced the villains to be something else, she said she always wanted to open a spa in France, turns good and thus becomes the Good Queen.
