Arriving at the past

This is how Arriving at the past goes in Lost in Time.

[We see the Iron Doom travelling in the Temporal Vortex]

The Overlord: A beautiful plot. No one will stop us.

King Sombra: Yes. Soon, the battle will be refought.

[Down below, Kai is shocked]

Kai: Yeah? I'll show him "no one."

[Wu wakes up]

Wu: Kai, Nya. Princesses.

Kai: Master Wu.

Wu: Where are we?

Princess Luna: More like, *when* are we?

Kai: Long story, but we're back in time. Forty years. When you, Garmadon, and the Elemental Masters fought Krux and Acronix at the monastery. Only this time, the good guys are losing.

Nya: We have to help you.

Princess Celestia: What did Sombra mean by "The battle will be refought"?

Wu: No. I have warned you before about the dangers of time travel. Change anything, change everything. In this time, you do not exist yet.

[The princesses are concerned]

[Wu passes out]

Princess Cadance: Change anything, change everything.

Kai: Here we go again.

[The Iron Doom slither towards the past where the battle between the Elemental Masters and the Hands of Time began]

[We see the past where the Elemental Masters have defeated Krux and Acronix]

Past Garmadon: Did Krux and Acronix just...

Past Wu: It appears they chose being lost to time over facing their punishment. The outcome is not as we intended. But Ninjago is now safe.

[Just then, the Iron Doom appears]

Past Garmadon: Look.

[The hatch opens as the Overlord and his minions arrive]

The Overlord: They look confident. Overly so.

Past Master of Lightning: Heya, Ice, am I seeing things or are those creatures?

Past Master of Ice: Indeed they are, Lightning.

Nightmare Moon: Yes, indeed. And our master was the archnemesis of Wu and Garmadon's father. He is the Overlord, Supreme Master of all villains, and rightful ruler of Ninjago! [cackles evilly]

Past Master of Lightning: Aw, I thought I was gonna finally go on my honeymoon. Really cute guy, too. Cliff is an actor and when I look into his eyes—

Daybreaker: Ugh, so much talking. You could use some fighting!

Past Wu: Stop! Focus, everyone.

The Overlord: Focus? Indeed. After you, minions.

[The Equestrian villains fight the Elemental Masters]

The Overlord: It's about time Ninjago bowed to the master of darkness.

[The Pony of Shadows fights the Master of Lightning and pins her to a wall]

Pony of Shadows: Such a shame about your honeymoon. I believe his name is Cliff Gordon, correct?

[She nods]

[The Master of Smoke runs to her rescue, but Chrysalis blasts him]

Nya: They've never seen these villains. They don't know how to stop them.

Kai: But we do. We've got to go help.

Twilight Sparkle: What?! Are you crazy?!

Kai: They need us.

Princess Cadance: Kai, Wu said, "Change anything, change everything."

Kai: I also heard Sombra: "The battle will be refought." Don't you get it? Things are already changing. For the worse. Besides, Master Wu also says "Never put off until tomorrow what can be done today." And if we don't help today, there won't be a tomorrow.

Princess Luna: Ugh, I can't believe we're doing this.

[They go out]

[The battle continues]

[Wu sees Kai and Nya]

Past Wu: Ray! Maya! You've returned!

Kai: [disguised voice] Uh, yes. And we've um, studied these warriors. To defeat them, you must find their weakness. [whispers in normal voice to Nya] You're right, he thinks we're our parents.

Nya: [disguised voice] We must work together. All of us.

Past Garmadon: I thought the forging of the Time Blades exhausted you.

Kai: [disguised voice] Uh, we rested and, uh... [normal voice] Look out!

[Sombra fires a powerful blast]

[They dodge]

[The Overlord scowls]
