It's probably for the best that Artemis was in a good mood from making such progress with Prolios, or she'd have probably scattered the boy's cards to the wind and left without a word. Instead she gives him a disinterested look and reads his mind. "I'll assume you don't mean by trying to kill each other with the cards. I have no concept of how to play your game, sadly." Her response is slightly annoyed, but she's bored enough to play along. How about taking a step back and talking to me from a normal distance instead of right in my face.
