Here's how the others arrived on Coruscant and Brian duels Chris in Revenge of the Red Diesel.
Sunrise: Mom, let me come with you!
Sunset Shimmer: There's no danger. The war is over.
Sunrise: But I disagree...
Sunset Shimmer: No! Stay here with the others till I return. Besides, K2 will come with me.
K-2SO: Oh, why do I have to be put up with these situations?
[They get on the ship. But Brian sneaks on board]
Sunset Shimmer: You ready?
Sunset Shimmer: Then let's go.
[Brian hides in the cargo hold, as the shuttle takes off. And it cuts back to Coruscant]
Chris: It's all taken care of master.
Ernie: (on Hologram) Good job. Rendivous on Kamino, I'll meet you there.
Chris: Yes, my lord.
[Then he gets attention of a beeping sound, and a monitor shows a shuttle heading towards the hideout]
[the shuttle then lands on the landing deck outside, and Sunset rushes out after spotting Chris]
[Chris races over to Sunset and they hug]
Chris: I saw your ship, what are you doing here, what's wrong?
Sunset Shimmer: I was worried about, Brian told me horrible things.
Brian: What things?
Sunset Shimmer: That you... turned to the Dark Side, and killed Younglings.
Chris: Brian is trying to turn you against me.
Sunset Shimmer: He cares about us.
Sunset Shimmer: Yes, he wants to help you. Chris, all I want is your love.
Chris: Love isn't gonna protect, our friends or us, Sunny. Only my new powers can do that.
Sunset Shimmer: At what cost? You're a good guy, don't do this.
Chris: I wonn't lose you. I have become more powerful than any Jedi Knight has ever dreamed of. And I'm doing it for you, to protect you.
Sunset Shimmer: Please come with me. Live in our house and raise our family. Leave everything while you still can.
Chris: Don't you see? We don't have to run away anymore. I've brought peace to the Republic. I'm more powerful than Ernie, I can overthrow them! And together, we can rule the galalxy, and make things whatever the hell we want them to be.
Sunset Shimmer: [walks back in shock] I don't believe what I'm hearing. Brian was right. You have changed.
Chris: I don't wanna hear about Snoopy. He and he Jedi turned against me, don't you do the same thing.
Sunset Shimmer: [voice breaking] I don't know you anymore. Chris, you're breaking my heart. You're going down a path I can't follow.
Chris: Because of Brian?
Sunset Shimmer: [tearfully] No! Because of what you done, and what you're doing! And what you plan to do! Stop! Please, stop this now and come back to me! I love you!
Chris: YOU'RE A LAIR!!
Sunset Shimmer: No!
Chris: YOU'RE ON BRIAN'S SIDE!!! YOUR HERE TO KILL ME!!! [slaps her down]
Brian: That's enough, Chris!
[We see Brian on the doorway]
Chris: (as Kylo Ren) TRAITOR!!! You turned her against me!
Brian: No! You did that yourself!
Chris: You won't take her away from me!
Brian: Your anger, jealousy, and lust for power already took care of that! You allowed that monstrous chicken twist your mind, until now... You've became the very thing you planned to destroy.
Chris: Don't push it, Brian. I see the lies of the Jedi. I do not fear the Dark Side like you. Can't you see?! I've brought peace, freedom, justice, and security to the Chicken Empire!
Brian: The Chicken Empire? Chris, my olegence is to the Republic, and the Resistence, to Democracy, dammit!
Chris: If you won't join me, then you're my enemy.
Brian: If that is what you wish. [he unclips his Lightsaber]
Chris: Try me.
[Brian ignites his Lightsaber as Chris then unclips his own and ignites it, then Force leaps back, and the two start furiosuly clashing sabers as "Obi-Wan vs Anakin" starts playing. As they go down a hallway and into a room clashing their sabers at breakneck speeds]
