[Leia glances down briefly at Barriss' feet, to see what's actually happening there now that she's close enough. It's an alarming effect, and one that has the potential to be even more dangerous than it already is, so Leia's priority at the moment is to somehow reassure her enough to reverse what's happening.]

Yes. I can explain later, but for now I'm going to need you to trust me.

[She doesn't know Barriss, she doesn't know what might be going on to cause this sort of extreme emotion in her, but the least she can do--especially to try and earn her trust--is extend a friendly hand. And to do that, she'll need to introduce herself.]

My name is Leia. I don't know if it means much to you, but I'm from Alderaan.
