Show her the power of the darkside

You enter the room Usajik lead you to and found a young human girl.
"You'll never make me betray the Jedi Order!" She yelled.
"It sounds more like you are trying to convince yourself than me. I never even said anything about the Jedi." You point out smirking.
"I . . . I'd never think about betraying the order." She said still resisting.
"Allow me to show you something." You shoot lightning from your hands and shock her body. She screams in pain and attempts to break her restraints. "Did you feel that power? A Jedi has never felt that kind of power."
