After Hansel trotted along with his ox for a while, he met Gretel at a bar on the way to the Kingdom of Grimm, their hometown. They were informed of a dragon that had attacked it.
Hansel and Gretel went back to the castle, and their parents apologized and explained what had happened. Hansel and Gretel decided to come up with a plan to stop the dragon.
Hansel and Gretel had rounded up an army, but their parents did not want them to go fight the dragon. They were angry with their parents.
With the help of a few talking ravens, Gretel managed to defeat the dragon by making him fly up really high than hurting him so he fell. The dragon was unconscious, but not dead. She then proceeded to finding her brother. She eventually made her way to a clearing were he was, and they went home, sad, but prideful.
It turned out that their FATHER was the dragon, so they cut his head of, and the dragon came out, and they killed it for sure, and with the twine Gretel got from the murderer, she put his head back on.
Shortly there after, Hansel and Gretel were crowned King and Queen of Grimm! And they lived happily ever after. Sort of.
