In the void, the Nowhere King faces down Horse and Rider, demanding the key. When he realizes that they don't have it, he decides to simply do away with them. In Centaurworld, the centaurs try to persuade the woman to let them back into the gate, but she is adamant. After she leaves, it turns out that Glendale had stolen the key and the enter anyway, and prepare to face down the Nowhere King. In the battle, Wammawink is thrown out of the gate and encounters the woman from before, who has returned after realizing the key was stolen. The two argue and Wammawink challenges her over her actions before reentering the gate.
The centaurs, Horse and Rider are soon outmatched, and the King traps them in his tar. The woman arrives, however, wielding the key, which she turns into a spear-like object. She prepares to stab the Nowhere King, who implies they have a history together, but falters at the last second. Horse and Rider steal the spear and charge the Nowhere King down, running him through and destroying him.
The group returns to Centaurworld, celebrating the King's defeat and the reopening of the worlds, but the woman arrive and warns them that the King isn't dead — he will reform, and return even stronger and more hateful than before, and now the key is gone as well. After she leaves them, Rider prepares to return to the human world to warn her general about the danger, but Horse chooses to stay — the human army isn't large enough to defend two worlds, and the centaurs need to be taught how to defend themselves. The two part ways once more, and Waterbaby accompanies Rider to the human world to keep a closer eye on the King's machinations herself.
Meanwhile, in the burnt wastelands of the human world, the King returns to an old fortress…
This episode contains examples of:
- Black Comedy: Glendale expelling the Lizardman Minotaur from her pocket dimension is treated as her giving birth, with her calling Rider's dagger "afterbirth". Her shifty glance while agreeing with Durpleton's assessment that the re-stabbed Lizardman is "sleeping" is a further burst of dark comedy.
- Brick Joke: That jacket Gebbery has been looking for? Glendale stole it, and uses it to console Wammawink.
- Dramatic Gun Cock: Durpleton does this with his own leg as he prepares to shoot tiny clones of himself
- Failed Attempt at Drama: At the end of the episode, the woman disappears with a dramatic burst of light, but Zulius then spots her rowing off in a boat a short distance away.
- Fastball Special: Horse and Rider reprise the maneuver from the first episode that involves Horse bucking forward to fling Rider towards the enemy. Rider expresses doubt it will work with Horse's new form.
- Freeze-Frame Bonus: During "Nothing Good", the woman pulls Glendale close for a line before tossing her away — and during that split second, you can see Glendale holding the key she's later revealed to have stolen back.
- I Choose to Stay: After the gateway is reopened, Horse chooses to remain in Centaurworld in order to help the centaurs prepare for the coming war and Waterbaby goes with Rider to take her place in order to protect Rider from the Nowhere King.
- I Meant to Do That: Glendale reflexively stole the key when the woman pulled her close, but didn't realize until Wammawink pointed it out after she started pulling items out of her stomach portal in reaction to Wammawink complaining about her kleptomania. Glendale claims that she did so intentionally.
- Reunion Vow: Even though Horse chooses to stay in Centaurworld to help the centaurs raise an army that can fight against the Nowhere King, she and Rider promise to reunite once the war is finally over.
- Shout-Out:
- There's a rather odd reference to Friends when Wammawink and the herd re-enter the gate; when Horse mentions that they're her friends and Rider disbelievingly says "Friends?!", the scene pauses over a still of the herd with a parody of the Friends logo, a snippet of Friends's theme song playing, and Ched clapping along to the theme.
- Ched suggests saving the day by "flying backwards around the world to reverse time", like Superman did in the 1978 movie. It's also a Take That! to that scene, as it's outright stated Ched only got an idea that outrageous due to being delirious from stress.
- Silent Credits: Episode 10's credits start the same way as episode 9, but because it ends overall on a hopeful note, the second half of the credits switch away from the creepy ambiance back to an instrumental of "Making Friendships—BOATS!"
- Skewed Priorities: After it's revealed that the Nowhere King knows the Mysterious Woman and has some kind of past with her, Zulius is more focused on finding out more about their history than escaping.Wammawink: Zulius, now is not the time! We've got to go!
Zulius: No way, we gotta stay! I think they have a history. I'll die if we go now.
Wammawink: We'll die if we stay! - Villain Song:
- "Nothing Good" is this to the Mysterious Woman, as she sings about her determination to see her mission through and the foolishness of letting affection blind you to what must be done.
- "Nowhere King Battle" is sung by the Nowhere King as he fights Horse and Rider in the Void Between the Worlds, where he brags that he'll take the Key from them by any means necessary.
