It's an inherited trait, apparently. Father can't spend very long up there either. Not to worry, I've found mother and she's since agreed to return to the Underworld, so all's well in my opinion.

[The Olympians still need to be taken care of, but that's a task for another day. Zagreus is happy with the current outcome.]

I'm sorry about that, mate. Especially after you'd been kept from each other for so long. Maybe she'll show up here eventually? I've heard it's possible. Either way, you'll return to the same home you left to get here, down to the minute, so you'll be on the same terms when you get back.
