Eva cocks her head as she cycles through what she knows of ghost-types and their diets, which is a lot considering she's not a type specialist. She can't say she's ever heard of souls going back into circulation -more so given they're absorbed into him, but then again, everything ends up dying at some point and feeding the cycle of life. In the end, she nods in (limited) understanding, deciding that's probably what he meant.

"It's still a form of eating, even if it's not a standard one. Probably look creepy or not like anything at all, but that tends to be par the course with aniivores. Either we get to see it or not, so-"

She shrugs a little; while she wouldn't mind watching him eat, it's probably rude to ask someone she just met. "That said, Nel-san's not that weird if she's a goat as they all have horns, and about half of all sheep breeds are the same, but I'm guessing that might not be the case in your world?"
