Marcille speaks slightly judgmentally: Cassius is weird. She has always found him weird, his specific combination of grace and clumsiness in seemingly everything he touched. For all her complaining, though, what she says is still wistfully fond. Zagreus is so easy-going that what seemed a strange fit at first makes more sense just because of its strangeness.]

And you probably have your own ideas to share about those things he wants to know.
