"A wonderful afternoon we have here, I offer you my greetings."
"You're awfully polite."
"And so are you."
The young woman responded to Arthur's words with a light smile. She knew that Arthur had long since sensed her presence, but hadn't done or said anything about it till Artemisia's senses picked up on something off.
Even Beatrix's spatial perception didn't detect her until she revealed herself.
"I said nothing because I sensed you had zero hostility towards us from the very beginning."
Hearing Arthur's reply, the young woman revealed a little bit of surprise, but it quickly disappeared when Arthur spoke once more.
"So? Who are you and why were you spying on us?"
Arthur's question was one Evan had already gotten an answer to. He appraised the woman the moment she appeared and had already shared copies of her status with the other three.
Even so, Arthur still asked and she obliged.
