Imprison and confront her

You enter the old, damp prison. Your prisoner is sitting down in a cell, hands and feet bound. She bares her teeth at you as you approach, but in her helpless state it is much more silly than intimidating. You give her a moment to calm down before you begin questioning.

"First things first: who are you?" She only stares at you, eyes filled with hate. "We could have killed you, you know, like we did to all of your comrades. Why don't you show a little gratitude and be cooperative?" She glares at you, refusing to break eye contact. "Anri." she says at last in a thick accent. You look over her features in detail for the first time. Anri's black hair has been dutifully braided across her head going down to a medium-length ponytail. She is thin and toned from the hardships of her training. Her face is sharp and beautiful, with a pointed chin that looks like it could cut diamonds. Her brown eyes match the flame of your torchlight with a fire of their own. You decide to proceed with the questions despite her tone. "Are there any more spies in the area?" "No." "Can I trust you to answer me honestly?" "No. If I plan on having a rescue or second attempt, I'd hardly give heads up, right?" You suppose she has a point. It's pointless continuing this line of questioning.

Time to get down to the real point. "Who gave you the orders and why?" She raises an eyebrow at the question. "Why I tell you?" You are starting to lose your patience. "Just answer the question." you say through partially gritted teeth. She smiles, glad to be getting to you. "It just not fair, yes? I mean, I answer question, but you don't answer mine, right? Then you go ask more. What's reason talk to you?" She gives you a teasing, sharp-toothed smile as she rocks back and forth like a petulant child. You're really starting to get mad now. Anri seems to have forgotten who is in control here.
