I've been wondering about this for a while and thought you could maybe give me an answer on the matter or an opinion. We saw that the Dead owning Alebrije was a common thing, going from Mama Imelda's Pepita, De la Cruz's chihuahuas and so on. But where's Hector's? Does he even have one? Pepita was still there even tho Mama Imelda couldn't cross the bridge so it brings the question. What happens to the Alebrije when his owner is forgotten? Does it 'live on' or follow him through the 2nd Death?
I’ve been wondering about the same thing, anon. I came to the conclusion, that perhaps not all Dead have a spirit guide for some reason. As for your other questions - I have no idea, since I’m not familiar with this subject. Maybe some of my followers know the answers to these questions?
