|Ninjago: Masters of Spinjitzu|
|Pause and Effect|
Pause and Effect is the seventy-second episode of Ninjago: Masters of Spinjitzu and the eighth episode of season seven.
The Ninja gather in the sewers in preparation to invade the Vermillion swamp, with the Ninja splitting up for different tasks: Lloyd goes to rescue Wu while Zane goes after Cyrus Borg, Cole and Jay go after the captured craftspeople, and Kai and Nya are assigned to find Acronix and Krux. However, the Time Twins have departed in search of the third Time Blade, taking Cyrus Borg with them before he can sabotage the machine they have forced him to build. Meanwhile, Wu is tormented by nightmares of his past failures with Misako, Garmadon, Morro and the Ninja while Commander Blunck and Commander Raggmunk guard him and bemoan General Machia's promotion over them. Lloyd soon engages the two in a running battle attempting to rescue Wu, while Zane-still bereft of P.I.X.A.L.'s help-tries fruitlessly to find Cyrus Borg. Cole and Jay locate the prisoners-including Karlof, Lou, and The Royal Blacksmiths-and attempt to get them to safety only to end up in a fight with the Vermillion.
Meanwhile, Kai has ignored his directive to find the Time Twins and located the blacksmith shop, where he finds his father Ray, seemingly confirming his fears about his parents' treachery. He soon engages his father in battle despite Ray's attempts to protest his innocence, but is eventually halted by Nya and their mother Maya. Their parents then explain that Krux and the Reversal Blade both returned to Ninjago after the Time Twins' defeat, during which both Krux and Wu saw a vision of the future that indicated when Acronix would return. After Ray and Maya hid the Reversal Blade, Krux gained their trust as Dr. Saunders before forcing them to aid in his plans rather than risk harm to their children. Unfortunately, the Time Twins make their return and, having learned the final Time Blade's location by listening in, force Kai and Nya to help them retrieve it in order to save Wu's life.
