This is how Dragon Twilight's rampage goes in The Return of Dragon Twilight.
[Dragon Twilight starts rampaging in Ponyville, while holding Princess Celestia prisoner in her tail.]
Princess Celestia: Twilight!
[Dragon Twilight brings Princess Celestia to her face and roars in her face, causing her mane to go straight]
Princess Celestia: You have to stop this!
Dragon Twilight: Why should I?
Princess Celestia: Look at the danger you're inflicting.
Dragon Twilight: So what?
Princess Celestia: If you don't stop, all of Equestria will be in danger.
Dragon Twilight: And I like it that way.
Princess Celestia: It doesn't have to be this way, Twilight!
Dragon Twilight: Yes, it does!
Princess Celestia: I can't let you continue down this path.
