Long after the defeat of the Evil Queen, Henry becomes a knight of the Wish Realm Enchanted Forest. When Henry's grandparents Queen Snow and King David are abducted seemingly by the returned Evil Queen, Henry sets out to save them. After witnessing her murdering Snow and David, Henry attempts to avenge them by hurling his sword at Regina, only for Emma to magically freeze him. Henry becomes determined to bring Regina to justice. However, Regina manages to escape with Emma back to Storybrooke, leaving Henry to become King.
