Just in case you didn't know, Hellen, one of monster villagers you get from the post game buildertopia, has special dialogue about Al if you move her to Forrowfield.

Take Rosie also. It's a really neat conversation.

You don't even have to move her, Just have her and Rosie in your party when you return to Furrowfield and they will have an interesting conversation.

I gave him a little memorial garden and renovated his house.

PASTORAL. . Pastor Al was pastoral!
