This is canonically how Harry Potter should have ended. With Harry and Draconia coming together to defeat Voldemort with a final Expelliarmus because they've perfected the power of love. The same love from his mother that protected Harry from Voldemort as a child now perfected as union between man and woman defeating Voldemort again as an adult. Voldemort thwarted by the thing he can't control: love. Draconia bringing honor back to Slytherin house, Harry coming full circle with the act of love that began the story, and defeating the villain with an anime level Gohan SSJ2 defeating cell Kamehameha wand battle. Absolute cinema.
