In 2017/18 I was really into story podcasts, and heard one that I cannot find again, and do not know what podcast I heard it on.
It was a sci-fi/horror short-story about a group of people who went into space and discovered a strange, blob like alien. This alien was not hostile and was able to speak telepathically. One crew member spoke the most with it and gained a sort of kinship with it. This alien kept asking him and the others to eat it. The main character refuses.
At some point, the captain is convinced and eats it. When he does, the alien takes over the body and says something ominous to the main character, some implication of its wider plan to learn more and grow.
My memory is pretty bad, so I did the best I could here.
