"Hey, didn't you like what I did? I did it just for you, you can't ignore me after that." The little girl remained there showing the body of the two elves to the human lying on the floor.
The little girl didn't notice, but the human girl was already totally mentally broken, she always had the weakest mind of all, and after all this traumatic experience and seeing all her friends die, she couldn't take it and ended up giving up everything.
Maybe it's not a good idea to give up on your life? She didn't want to do that, but she thinks she can't escape from here, and since all her friends are dead, she better die, too, so she just disconnected from the outside world and is not paying attention to anything anymore.
She basically hid in her own mind, she is ignoring everything around her, she cannot hear anything, and she cannot see anything, so she will not answer the little girl no matter how much she is showing their bodies and calling she.
