Am I two months late? Maybe. Unfortunately, I don't listen to episodes in a normal, discernible order, so I never feel fit to comment because I'm inevitably behind the times. But this story drove me BONKERS (in a good way) so I wanted to put my thoughts into words.
The opening. You can always get me with storms raging on dark nights, and someone (or is it something?) begging to be let in is such a classic, and it really works here. You know something is very, very wrong without immediately giving it away. Why can't we trust the knocking at the door? What else could it be? It cracks the reader (or, well, me) wide open. Suddenly you want nothing more than to figure out what else could be behind that door.
The fact that the fear is not necessarily rooted in fear itself, but love. The Pact was made to save the patriarch's family. Eleran loves her goats. If it had ended there, the story would fall into the general Lovecraft vein of "scary community (separate from MC) does weird things out of 'love' that is SECRETLY devotion to an ELDER GOD". Which, I don't know, it can be fun, but not necessarily interesting. Having the MC grapple with the fact that she cannot stop loving something the audience expects to fear adds so many more dimensions.
The fact that there really aren't any "right answers". The things the MC does "wrong" (not leaving out the tubers, shooing the goats out of the barn) are perfectly rational given the information she had. Later on, is she supposed to open the door? How is she supposed to react to what happens to Ebun? There's so many paths to explore here, so many 'what if's to follow. This is a story that can be pulled apart, picked through, and reassembled without losing any of its impact.
Also, yeah, goats are just kind of like that. Love those funky lil ungulates.
