Alea reeled back when the dead blocked her path. If they caught hold of her she'd be in trouble, but as long as she kept away from them she had a chance. She backed away from them, looking around uncertainly for another escape route, or something to hide behind. Luckily, it seemed like the creatures were pretty slow. She could probably keep away from them without too much difficulty if it came to that. That just left the evil man....
He spoke to her, so obviously she had been noticed. Nothing terrible had happened immediately, so she was probably okay for the moment. From the looks of it though, there was no obvious escape. She was stuck, pretty much at the mercy of her captor. The only way out was through him...one way or another.
When he told her to approach him, she balked instinctively, and not just because he was clearly evil. She rejected being told what to do, and anything an evil man like this wanted her to do was probably not in her best interest. She backed toward the far wall, trying to keep her eye on the walking dead and the back of the evil man. She wondered if she could break through one of the walls before they could catch her. ...Probably not.
Struggling not to panic, she wracked her brains for the best way out of the situation, but it was completely unfamiliar to her. Negotiation was probably her only option at this point, but she had no idea what would appeal to the barely-human man. She tried to speak, and managed it on the second attempt. In a fairly level voice that betrayed only a touch of tension, she asked, "How can I convince you not to kill me?"
