Secrets Discovered (LEGO Ninjago)

Secrets Discovered is the seventh episode of the seventh season of LEGO Ninjago: Masters of Spinjitzu, and the 71st episode overall. It aired on Cartoon Network on May 23, 2017, in the United States.

Plot
Secrets are revealed as Nya confronts the Samurai X imposter, Kai pursues the truth about his parents and the other Ninja desperately seek to locate and rescue Master Wu. But as usual, some answers only lead to more questions.

Why It Sucks

 * 1) This episode is about the ninja saving Master Wu, but they barely do anything at all.
 * 2) The title of this episode is kinda laughable.
 * 3) Like most Season 7 episodes, the ninja are out of character.
 * 4) The sub-plot of Kai pursuing the truth about his parents, while interesting, goes nowhere.
 * 5) Instabook feels like an unnecessary parody of Instagram and Facebook, and an attempt to be hip.
 * 6) It has the worst plot twist. Samurai X (who later revealed to be Pixal in Season 8) just "reminds" Nya that the reason she hid her identity as Samurai X back in Season 1 was because her friends and love ones would "be at risk". Not only that, it is absolutely nonsensical. Why would she be putting her friends at risk, when they 're the PROTECTORS OF THE CITY?
 * 7) The pacing is pretty weak and it makes the episode hard to follow.
 * 8) A few errors, like although Cole's Rock Roader was seemingly destroyed in "A Line in the Sand", yet in this episode, it still functions properly.
 * 9) Unnecessary dialogue that makes us feels forced and weak.

Redeeming Qualities

 * 1) Decent writing.
 * 2) Although it goes nowhere, the sub-plot of Kai pursues the truth about his parents is interesting.

Trivia

 * The intro of rock song Lloyd listens to on his radio as he leaves the Temple of Airjitzu on the Destiny's Shadow sounds very similar to the beginning of the Chuck Berry song, Johnny B. Goode. It also sounds similar to Dareth's song from "Spy for a Spy".
 * In the secret room of Kai and Nya's father's blacksmith workshop, there are two curtains with a fire and water symbol on them with the exact same design as the symbols for the Fire Nation and Water Tribes in the show, Avatar: The Last Airbender. Tommy Andreasen said this was most likely due to a lazy designer.
 * The Destiny's Shadow makes its debut in this episode. In the closed captioning of the episode, it is actually called the Daring Bounty, which may have been an earlier unused name for the vehicle.
