Ninjago, Season 5: Possession

[Wu summons his dragon and finds Morro struggling to break free of the Preeminent's grasp]

Wu:
Take my hand!

Morro:
Why, so you can take the Realm Crystal and use it to find your own prized pupil?

Wu:
You are all my prized pupils, but none of us can do this alone. You're strong, Morro, but it takes others to make us stronger, even me. Take my hand, so we can be stronger together. Please, Morro!

Morro:
[grabs Wu's hand, then glances at the water] You can only save those who want to be saved. Goodbye, Sensei. [gives Wu the Crystal before letting go, allowing himself to be pulled into the water, killing him]

Wu:
[screams in despair] MORRO!!!
