“A strange tea lady just marooned us in the Realm of Oni and Dragons. A realm, mind you, we know nothing about with no hope of getting home, and no clue as to what else is out there!”
Ninjago City under the control of the Sons of Garmadon.
On the streets of Ninjago, a figure wearing a green cloak walks through the streets which are now terrorized by the Sons of Garmadon. A clip appears on the monitor, Ultra Violet is hosting her show and it's revealed anyone affiliated with the Ninja or opposed to Garmadon who has become Emperor is rounded up. Violet reveals that Ronin is the latest catch and the Police Commissioner is next on the list.
As the figure continues walking, he is accosted by two members of the Sons of Garmadon, both wearing vandalized police uniforms, who remind him it was illegal to wear green. The person is revealed to be Dareth, who tries to intimidate them by calling himself the Brown Ninja but the two see through his bluff and let him go, but steal his food.
Dareth immediately came up to an alleyway, moving a dumpster aside and heads into what appears to be a cold storage unit where he sees Nya and Lloyd, training to try and regain the latter's powers, which are still inactive. He tells the bad news about his supply run to Misako and P.I.X.A.L. before getting out an old and moldy Puffy Potsticker he had been meaning to save but chooses to give it to Lloyd to keep his strength up. The Green Ninja reluctantly eats it before resuming training.
In the Realm of Oni and Dragons, Kai manages to find some foil, making everyone excited as they try to use a radio, made from around the remains of the Destiny's Bounty to contact home. As they talk about their situation, someone complains that they're hungry. The person is Wu, who is now a child as Cole lectures him on rationing before the impatient Kai tells him to go hunt for some, and Cole decided to accompany him.
As Kai and Zane listen on the makeshift radio, Jay, who has lost his grip on reality, plays on his homemade game, which is a piece of wood. Zane soon tells them he has gotten a transmission and they believe its from Ninjago. However, the people on the other side state they are preparing something and Zane translates some phrases to Kai that they are talking about an ambush. Hearing this, Kai realizes they are talking about them and tells the others to run away. As the trio run, figures are seen in the fog and quickly grab each of the Ninja in chains and drag them off.
In Ninjago, Lloyd's group tries to evade Killow, Mr. E, and their grunts before they discover they are boxed in. The five soon find the wreckage of the Bounty and are sad at its destroyed state. Lloyd finds the picture of him and his friends before finding a leaf for Traveler's Tea and alerts the others of this. The group investigates the ship more and see half of it has disappeared, realizing that their friends were not killed but teleported elsewhere. This gives them hope before their enemies show up and prepare to attack but Karlof punches Mr. E away as Griffin Turner and Shade appear. The three take down their foes as a garbage truck driven by Skylor picks them up and everyone retreats.
Cole and Wu managed to find food, but when they return, the two discover their campsite has gone and tire tracks left behind. Wu decides to follow them as that might lead them to their friends and Cole follows him. Meanwhile, their friends are brought chained and blindfolded into the lair of the Dragon Hunters, who take off the blindfolds for them to meet the Iron Baron, who taunts them on their situation.
This is the second season premiere to recount the previous episode, the first was that of Season 2, and the second was the premiere of Season 10.
It's also the first season premiere to recount an entire season so far.
Garmadon is the announcer of the episode titles now, replacing Lloyd since "Big Trouble, Little Ninjago." Interestingly, his voice when announcing the titles sounds like his evil form now as opposed to the previous episode, when it sounded like his Master form.
Likewise, he is the first non-Ninja character to be in the introductory eye-graphics.
Ronin briefly reappears in this episode, thus making this his first appearance since "Scavengers," but he is caught and taken away to Kryptarium Prison by the Sons of Garmadon.
Wu has now aged into a child-like he was around the time his brother was bitten. He appears to have lost his memories of his old life, as he questions Cole calling him "master" and denies being a Ninja.
But previously as a toddler, he seemed quite aware of his older self's memories, despite having a younger mind. The reason is unknown.
It is likely that the reason is infantile amnesia. Where you lose memories as an infant or toddler when you grow into a child.
Nya confirms Jay is her boyfriend. They have been together since the finale of Skybound, but this is the first time their relationship has been directly stated.
When Cole and Wu are running from the Dragons, they hid inside a cave. Inside the cave, there are a series of paintings on the walls, most likely drawn by Dragon Hunters.
Despite being the episode being called "Firstbourne" it did not feature the Firstbourne in any way.
Whenever the scene switches to Ninjago, it switches with a short blast of Destruction and whenever it switches to the Realm of Oni and Dragons, it switches with a short blast of Creation.
The picture Lloyd and the others found is a group shot of the Ninja in their original appearances, from the second Season 2 intro.
The opening scene is supposed to replicate the Season 8 intro but in the post-apocalyptic Ninjago City after Garmadon took over.
It is shown that while Zane, Jay, Nya, and Lloyd are wearing new suits entirely, Cole and Kai are wearing their partially ripped suits from the last season.
Jay pretending to play a video game is similar to when he threw a rock into a can and said it was a "new highscore" in "Home."
