Ninjago S9: Dragon War

After 'Big Trouble, Little Ninjago', the ninja wind up in the realm of the Oni and Dragon, and encounter four elemental dragons, who plead them to save their kingdom, for they have the 'essence of the Lost Prince' on their bodies. Jay immediately realizes what this means, and pleads them also to help them get back to Ninjago in exchange for help, in fear for his friend.
Meanwhile, Lloyd is mourning his fellow ninja, who he thinks are dead, until Mistake reveals that they are in the realm of the Oni and Dragon, and to get there, Lloyd must face his true fears of his blood, for it is the only way to cross over, and get not only his powers back, but have control of all the elements. But, out of fear of becoming a monster, he refuses, and comes face-to-face with Harumi, who attempts to kill him. Yet in a sudden outburst of draconic energy, he finds himself feeling weaker and weaker the longer he goes refusing to accept his bloodline.
What will happen now?
