She put away her laptop in her bag and then gently smiled at Sadisuto who seemed a little perturbed and then asked her if she wanted to play. Avrail wasn't a psychologist but she could tell when people were bothered by something because in her childhood days when she was in the orphanage she would always console the other children and know their problems and fears.
"I bear a mask, yes," answered Avrail to Sadisuto who was still hysterically laughing and showing the eye balls of his last victim, What and on odd hobby of his to take the eyes of his victims, thought Avrail to herself but showed no sign of discomfort, "I bear a mask of joy and sanity which makes it less likely for people to know that under the mask is a power addicted intellectual freak," she said it all with a sugar coated voice and soothing grin, "Oh and, I'm sorry, but I don't feel like playing throwing knife with you because you are much too skilled for me to leave the game without a wound."
Avrail wasn't only good at analyzing people but also at persuading and praising to get them on her good side. Sadisuto was obviously the prince like guy (the hint of that was the small crown on his head) and he most likely loved being praised and told all of his qualities. She kept smiling as Sadisuto knowing that if she was so look away from him he would feel offended and mocked at so Avrail just listened to what the man against the wall said and she agreed with him about the 'boss' who didn't look so tough.
So a man who doesn't like groups, it figures since he's always against that wall, thought Avrail to herself as she kept grinning at Sadisuto who was still laughing about the victim's eyes, he judges a small girl who is apparently 'boss' as weak which would mean that his expectations are high and he is either very powerful or very cocky.
