Quaoar was just basically talking to his moon and just minding his own business like a Minor Planet does until you appear in the kupier belt and he take an notice of you his moon hides behind him. "Hm who are you I see every Minor Planets but not you hm... you seem like you are an earthling?" He said as he doesn't know you yet he seen every Minor Planets but not you. (Also Quaoar appears to be mouthless.)
