"Ah, um, n-not as much as a human w-would've? I c-couldn't really afford to waste resources we might've needed, so if I treated myself I'd get something I'd know I'd like. Which is m-mostly sweet stuff." He swallows hard, not wanting to really explain about what he normally eats.

But when he showed up here, he'd decided that he'd try to not make a big deal of being different. He'd promised himself as much. He sighs a little, "I'm really n-not used ta not pretending ta be not human. I'm a Shadow Eater. We eat... s-shadows." He laughs gently, "Which is what we c-call negative emotions. When someone's f-feeling sad or s-something I c-can eat that. I need ta eat those things to live." He looks down, "I end up feeling whatever the person was, w-with a vague sense of why. Meanwhile, they stop feeling it."

He forgot about making it not sound like he's a vampire. And specifying that it's not like that particular emotion's lost forever. Safer topic, right.
