Time rewinds from when the Iron Doom heads into the Time Hole, then from Kai falling off the dispersing Fusion Dragon, all the way to the moment Acronix was about to give the order. "Head fake." He said.
"Not this time." Kai replied as he has the Fusion Dragon fly down to Nya and Dragon.
"We must make sure the future is not affected." He said as they jump onto the dragon. The Fusion Dragon turns around to fly back to where the Iron Doom is as Dragon looked at his past self. "Dragon. Catch." He throws the Reversal Time Blade to him and he catches it.
"The Reversal Blade." He said as he looked at it. "But how?"
"Who knows?" Oni asked as he came up to him. "But it's too dangerous to keep. The Boiling Sea." Dragon starts to take off.
"Find Mistaké." Present Dragon said as the Fusion Dragon starts heading for the Time Hole. "Drink Obscuri-Tea, all of you."
"Go!" Kai yelled as he and Nya force the dragon to go up. "Go! Go!" The Iron Doom soon heads into the Time Hole as the dragon did so as well and the Time Hole closes.
Present
The temple and buildings in Ninjago City immediately turn back into the original state. "Guys, you won't believe it." Jay said as they soon look on.
"Ninjago is back to normal." Cole said.
"My technology has returned." Cyrus said as he looked at his BorgWatch.
Blake suddenly came up next to him. "Did something just happen?" He asked.
"Blake!" He soon hugged him.
"Whoa, dad, wait!"
Close by, Zane, back in his Titanium form, starts up and stands up. "I believe something just overloaded my sensors." He said, dusting himself off. "Did anyone else feel a temporal disturbance?" Samurai X comes up next to him.
Jay immediately chuckled. "Kai and Nya did it." He said before running up to Samurai X and hugs him. "Wanna celebrate by telling me who you really are?"
"No." Samurai X replied.
"Everything is fixed." Maggie said, placing her arms around Blake and Lloyd, who had his hands on Gewuji's shoulders. "Yeah!"
They soon hear Ray coughing and turned to him. He was now in a much worser state. "Fate of Ninjago." He said, weakly before closing his eyes.
"Not everything." Maya said to the others.
In the time hole, the Iron Doom moves along as Krux took off his helmet and turned to his brother. "Must we go to the future?" He asked.
"If we travel far enough ahead in time there will be no one who knows us." Acronix replied as he took his helmet off. "No Elemental Masters. And best of all, no Kai and Nya."
"Wow, you just keep getting it wrong, don't you?" Kai was soon heard as they turn to see him, Nya and Dragon. Kai was holding Leo while Nya held a regular katana.
"Huh?" They both asked.
"That's gotta be really, really frustrating." Nya said.
"No." Acronix replied. "It's impossible. It ends now!"
"Indeed it does." Dragon said. "And we shall end it together."
Krux and Acronix pull out swords of their own and prepare to strike them as Kai blocked Krux's swords while Nya and Dragon blocked Acronix's before they try to strike back, only for all their attacks to be blocked. Acronix tries to strike Nya, but she blocks the attack before trying to strike Dragon, but he too blocks it before Acronix forces them back. Krux charges at Kai, who moves to the side and blocks his swords before trying to strike back, only for his sword to be knocked back. Close by, Nya and Dragon clash with Acronix before they force him back and Dragon uses his staff to stop his swords before backing away. Krux tries to strike Kai, only for him to block the strike while backing away and then another one as Kai steps onto the controls while blocking every strike Krux threw at him before forcing him back, making him let go of Leo and slip out of the cockpit. Luckily, Kai was able to grab hold of a piece of the armour and looked up to see Krux holding his sword at him. "You'll never interfere again, boy." He said as he was about to strike, but he soon screamed as he felt something sharp hit the back of his left shoulder. It was Nya's switchblade, which was a wedding gift from Lloyd and Dragon, making him back away as Kai quickly manages to crawl back in, pick up Leo and charge at Krux.
Dragon blocks a strike from Acronix before he turns to see Krux, bleeding from the back of his left shoulder as the switchblade was still in him. "My brother needs my help." He said before turning back to Dragon. "I'll deal with you soon enough, old man." He immediately kicks Dragon down and charges at Kai and Nya.
With this distraction, Dragon looks out from the cockpit to see the Ninja, Cyrus, Samurai X, Ray and Maya. "We are passing through the present." He said as he looked at Ray. "Ray, my old friend." He turns to see the Asher siblings on the ground as Acronix removes the switchblade out of Krux's back and threw it aside.
"Goodbye, children." Krux said as he and Acronix raise their swords.
"No!" Dragon vaults out of the cockpit, causing Acronix to scoff.
"There is nothing you can do." He said.
"Except what must be done." He jumps down to the Apparatus and pulls out the Reversal Time Blade before using it as a brake by jamming it into the Apparatus.
"No!" Krux yelled as the Iron Doom starts to shake. "Fool, you'll destroy us all."
Dragon starts moving around the Iron Doom as it spun out of control before jumping up and lands inside the cockpit before grabbing hold of Kai and Nya as they were about to fall out. "How did you do that?" Nya asked as she held Kai's hand.
"Why did you do that?" Kai asked.
"You will know when you arrive." Dragon replied before noticing the switchblade nearby. "And, Nya, I'm glad you liked my gift." He soon lets go of Kai's hand.
"Master, what are you doing?" Nya asked as she soon grabbed Kai's leg and he holds onto the edge as Leo slipped out of his hands, falling somewhere into the timeline.
"Putting off until tomorrow what cannot be done today." He then threw the Reversal Time Blade at them, causing Kai to let go as they fall out of the Time Hole, screaming. Back on the Iron Doom, it straightens itself as Dragon gets up, picks up the still blood coated switchblade and poised. "As you said, Acronix. It ends now." The Iron Doom twirls as it moves along the Time Hole.
In the swamp, a time hole opens and Kai and Nya fall out of it. "Kai?" Lloyd asked.
"Nya?" Jay asked as they soon land in the swamp water.
They quickly surface, get onto the walkway and come to them. "Mom?" Nya asked.
"Dad?" Kai asked.
"Can't...hold...on." Ray said, very weakly and his voice sounded like he was whispering.
He groans as Kai and Nya came up to their parents. "I'm afraid he's close to his end." Maya said. "There's nothing to be done."
"Yes, there is." Kai replied, showing them the Reversal Time Blade. He moves it over his father's head and slowly touched his forehead, causing yellow energy to surround him. Everyone looked on as Ray soon turned back to normal and he opens his eyes.
He sighed as Nya helps him up. "My children." He said.
"Dad." They both replied, hugging him, relieved that he is cured.
"Oh, you guys." Jay said. "Let me get in on this."
They soon came close as Geoff then looked at the Reversal Time Blade. "We don't have much time left." Geoff said. "There's still someone to be cured."
"Right, let's go." Kai replied before they all take off.
On the way to the Temple of Airjitzu, the Ninja were riding their Elemental Dragons with Ray on the back of Kai's while Maya was on Nya's and Cyrus was on his son's. Samurai X took off just as they were leaving and they know that they would meet him again. As the temple came into view, Ray and Maya were amazed before the Ninja immediately disperse their Elemental Dragons and head over to the entrance while Blake carried his father on his back as well as his wheelchair.
In the study, Tania was now looking like a very old woman with pale skin and white hair as she struggled to breath before the doors burst open. "Mom!" Geoff knelt down to her and Ray and Maya look at her as Blake put the wheelchair down and sets Cyrus in it.
"Mom, we found the Time Blade that can help you." Gewuji said as Kai handed Geoff the Reversal Time Blade and he moves it to her, with the blades lightly touching her, causing yellow energy to surround her.
Tania was soon back to normal before she opens her eyes and looked at her children. "Am I... okay?" She asked.
"You are." Geoff replied. Tania wailed a little before hugging her children.
She then noticed Ray and Maya. "Ray. Maya. I'm sorry."
"Don't be." Maya said as she smiled. "Chen fooled you. But, in the end, you have two children, who have your powers, like ours."
"But, we have a lot of catching up to do, and you may tell us some." Ray said.
"I know." Tania replied before looking around. "Where's Master Wu?"
"He's still on the Iron Doom." Kai said, finally realising the situation. "He stayed aboard to deal with Krux and Acronix."
"And now he's gone." Nya replied.
