Xiao's mind was getting jumbled from the things that were taking place. Seeing the mischief in Valencia's eyes, Xiao understood that this was some kind of revenge from Valencia, but that's what was worrying him because she wasn't supposed to be like this!

It's only later down the line when she meets her second master that she truly begins to change. That's where the terrifying Valencia is born.
