|Ninjago: Masters of Spinjitzu|
|The Quiet One|
The Quiet One (also known as The Quiet One Revealed, Part I) is the 80th episode of Ninjago: Masters of Spinjitzu.
Lloyd and Harumi are stranded in Primeval's Eye looking for the third Oni Mask.
The other Ninja have crash landed somewhere nearby and begin to work on the ship where Zane has a talk with P.I.X.A.L. about her activities. Zane states he is happy she has a body once more and is proud of her actions as a heroic vigilante.
Meanwhile, Lloyd and Harumi continue their journey and deal with dangers of the jungle and Harumi begins showing a strange side to herself.
As the Ninja continue their work, The baby begins showing a strange side as it helps with repairs and drinks tea. After Jay remarks he is done with these sights, the baby speaks and uses a familiar quote "Ninja never quit" and Jay tells his shocked friends the baby is Master Wu. The Ninja tell Nya and P.I.X.A.L. of the things the baby did and how they discovered he is Wu de-aged. Nya doesn't believe that he is actually Wu however, she soon does believe after she hears the baby talk and drink tea like her Master does.
The Ninja watched him go for more tea, which Jay refills for him. Afterwards, questions are raised by how Wu reverted to a toddler; Nya deduced it was because he touched the Reversal Blade before he was lost in time. Zane states if Nya's theory is correct, the Blades' effects have worn off and now Wu will keep aging until he returns to normal, eventually.
When computers on the bounty are fixed, P.I.X.A.L.'s scan for the Quiet One is completed, and the ninja realize that the Quiet one is Harumi. The ninja quickly realize that the Quiet One is Harumi. They try to warn Lloyd and stop Harumi only for Ultra Violet and the Sons of Garmadon to stop them and capture the Ninja.
Meanwhile, Lloyd and Harumi narrowly survive falling off a waterfall, and discover the entrance to the Oni temple hidden at its base. Harumi evilly smiles to herself while Lloyd walks off, unaware of the truth.
