This is how The Fallen captures Twilight goes in
[An unconscious Twilight wakes up to see the Fallen]
The Fallen: Hello, my little one.
Twilight Sparkle: [gasps] You.
The Fallen: Yes. Me. And now you're going to give me what I want.
Twilight Sparkle: [pretends to be confused] What?
The Fallen: The symbols in your mind when you and your five friends touched the second last fragment of the Allspark.
Twilight Sparkle: [still pretending to be confused] I don't know what you're talking about.
[The Fallen uses telepathy and Twilight's horn lights up on its own and projects the symbols]
The Fallen: You were saying.
Twilight Sparkle: No way.
The Fallen: These symbols will lead me to my Star Harvester.
Twilight Sparkle: What's that?
The Fallen: It's a machine that harvests Energon by destroying suns.
Twilight Sparkle: [gasps]
The Fallen: And now you're gonna give me the information of the location.
Twilight Sparkle: I'd never do that!
The Fallen: We'll see.
[The Fallen then tries to use mind probe on Twilight to get the information of the location where the Star Harvester is, but to his surprise, she ends up resisting him and ends up reading his mind]
Twilight Sparkle: You're afraid...that you'll never win if Optimus defeats you.
