"That is a lot of siblings! I don't even think I have anywhere near that many cousins. And Lord Uncle Zeus is very prolific." Prolific enough that he'd also gained a new cousin while here. Really, Zagreus seemed to have extra relatives popping up all the time.

But then Zagreus blinks, and thinks about the numerous names he'd just heard. "No, I don't believe I'm familiar with any of those names, I'm afraid. But...wait. Did you say the god? As in, just the one? I heard about something like this from Claire, but...you're saying there is actually a real pantheon out there with just one god?"

He looks like he can't quite believe it. Certainly he still finds the very concept of having just one god incredibly strange. You might as well tell him that there's only one star, or just one mountain.
