Ghost Story

"Ghost Story" is the second episode in the fifth season of Ninjago: Masters of Spinjitzu, and the 46th episode of the series as a whole.
==Plot==
As Morro catches up to the Destiny's Bounty 2.0 on his Elemental Dragon, Wu orders the Ninja to prepare for battle. The Ninja have equipped themselves with weapons, since they lost their powers earlier that day. Jay mounts one of the cannons to fend him off, but the ghost eventually boards the ship. Morro then summons twin ghost blades, and Cole and Jay arm themselves with swords and hold him off, while Zane and Kai take Wu below deck to make an imprint of the staff's secret message, leaving Nya, Cole, and Jay attempting to stop the possessed Green Ninja. Morro, however, cripples the autopilot and confronts Kai while the others attempt to stabilize the ship again. Kai is almost thrown out of the Bounty, but Wu tosses his staff away as a distraction, and Morro summons his Elemental Dragon to retrieve it. The Bounty eventually crashes in the Forest of Tranquility, though the Bounty remains intact.
After looking over the symbols, Zane sends the Falcon to fetch Misako for her to translate them. That night, Wu tells the Ninja of how he met Morro when the child was looking through the Monastery's trash cans in search of food. With Garmadon having left to train under Master Chen, Wu took pity on him and trained him in the ways of the Ninja. He soon discovered that Morro was a descendant of the Elemental Master of Wind and Air, and believed him to be the Green Ninja. This ended up being his greatest regret, as the thought of the power that came with the title made Morro incredibly arrogant, and he flew into a fit of rage when the Golden Weapons did not react as they did when they eventually revealed Lloyd. He then left to find the Tomb of the First Spinjitzu Master to prove he's worthy of being the Green Ninja, but never came back. Wu, while sad he was sent to the Cursed Realm, tells the Ninja and Nya that they must stop Morro in order to free Lloyd and get their Elemental powers back.
Meanwhile, Morro lands at a Biker Tavern, and after having a drink, disrupts several bikers' pool game to learn of the staff's secret message. He is soon surrounded by several bikers, but he uses the Allied Armor of Azure to summon Wrayth and the two defeat the bikers with ease. Morro sets off to the Library of Domu while Wrayth creates the Chain Cycle to hunt down the Ninja.
That night, Kai dreams of him promising to look after Lloyd, only for the Green Ninja to be eaten by a Fangfish. He is awoken by a walliper to find that Misako has arrived, and discovered that the first symbol means Airjitzu, a martial art created by Master Yang. Zane, however, reveals that the Airjitzu scrolls that are housed in Domu have recently been stolen by Ronin, though the Ninja realize that since Morro is unaware of that, they have a headstart. The Ninja mount on the wallipers to head to Ronin's home town of Stiix, while Misako and Wu order Nya to come back with them to Steep Wisdom. Kai volunteers to lead the Ninja to Stiix.
In Domu, Morro discovers the scroll is gone, and asks a monk where it is. He begins to tell him about Master Yang, but after being intimidated by Morro, he reveals that Ronin took it, in which Morro sets off, being only slightly held back by two monks who want his autograph and a selfie. In the middle of the desert, Kai is leading the team towards the sun, though Zane reveals to them that they are heading west, and Stiix is in the Eastern Coast: ergo, they should be moving away from the sun. Jay is stunned he's telling them now, though the Nindroid admits he wanted to let Kai lead. Cole berates Kai for going by gut instinct, while Jay realizes the team looks to Kai whenever Lloyd is gone, when they should really follow Zane since he's a walking computer: Cole agrees since he's the more logical choice. Kai refuses to listen, but is forced to follow because of his walliper. They soon find train tracks leading to Stiix and follow them.
Back at Steep Wisdom, Nya sadly contemplates not being able to join the Ninja, while Misako pushes Wu to tell her something. He says she's not ready to know, though Misako points out how long he waited to tell the Ninja about Morro, and tells Nya they didn't hold her back to fix the shop. Nya is surprised and asks why she was: Wu states there's something he never revealed about her parents, though Nya stops him and reveals that Kai told her what Chen told him, which caused them to look into it, and confirm their father was the previous Master of Fire Flame Heat Warmth Burn Burning and Hot, which she isn't surprised by. Misako then points out that their mother was the previous Master of Water Seas Tidal Waves Oceans Tides and Fluids, which she is surprised by. Wu then says that since Kai took on the traits of their father to become the Fire Flame Heat Warmth Burn Burning and Hot Ninja, Nya must follow in their mother's footsteps and train to become the Water Seas Tidal Waves Oceans Tides and Fluids Ninja: upon hearing this, she drops the jar she's holding and faints, causing Misako to realize she really wasn't ready to know.
By nightfall, the Ninja find a train station to take a break. They are soon ambushed by Wrayth, who attacks them on the Chain Cycle. Wrayth turns Cole's walliper into a Ghost, and the Ninja set the wallipers free. After a long battle which causes Wrayth's chain blade to get stuck in a support to a nearby water tower, a train to Stiix hits Wrayth, but since he is a ghost, he passes right through. However, the water from the water tower falls on Wrayth and he explodes into green goo. The Ninja soon discover that water is the ghosts' weakness, and the episode ends with the Ninja chasing a train to Stiix, and telling them to slow down so they can get on.
