[Spoilers E105] Incompatible Heavens?

In a world with a pantheon of Gods who live on different planes, what happens when a mixed faith family passes on? Could Vex and Vax ever see each other again in the afterlife? (Especially given his status) What about Percy and Vex? What about Pike? She's faithful but Grog isn't. Where do the faithless go?

It's such a fascinating area for mythology in Critical Role. I'm obsessed with this chapter.
