At Thalia's words about the Greek goddess Artemis, Maka tilted her head and looked at her. Really looked at her, focusing her spiritual energy until... there, her spirit. Large, much like Kid's had been before he had assumed his true shinigami powers at Lord Death's... death. She got a feeling for the girl, much like she did with all others, but only vague and undefined. Nothing that made Maka distrust her.
"You're not human," was what Maka eventually said, brows furrowing. "Your soul, it looks like Kid's before he became Lord Death. What are you?" Then, realizing how intrusive her question sounded, Maka then waved a hand a bit. "I'm sorry, I don't mean to pry about that. I can just... see souls, and yours is not the soul of a human."
