Ash and the entire party went down the stairs after entering the door to sixth floor. Raven and Rose stuck on to each other after the dirty display Ash has shown them by killing the fairy queen.
Quinn came near Ash and asked "You did a good job, but do you have to go that far?" holding his laughter inside.
He was not disgusted or ashamed at what Ash has done, but he felt that doing it is too far.
"You wouldn't understand, but I was venting my anger on her." replied Ash with no regret in his face.
In fact he was feeling proud of himself for killing the fairy queen like that. This may look very disgusting and dirty to many but killing her has boosted his confidence from before.
The girls did not buy those words one bit because they looked Ash like a pervert and a sadist. Ash did not bother to talk to them because it is hard to change their minds when they start thinking the other guys is a pervert or in a negative way.
