"Why is Damontry wearing a black dress?"

This is what Sivana whispered after she approached her brother, who was frozen in his area, and he nodded his head in a sign of 'I don't know'..a mixed feeling, is he supposed to feel happy because  Damontry  looks so beautiful.. in his dress, did he reject it?  the gift !  If the answer is yes, then why didn't the two maids tell him, and if no.. why didn't you wear it!!.

He expelled those thoughts from his mind to swallow his lump and proceed to approach them while the other was heading towards him.

"Oh my God, I didn't know you."
