I don't understand your post. You provided the link to the episode in question.
What exactly is "missing"?
Ah, I see that other episodes are available to watch on IMDbTV, but this one does not have such a link. When I click the link Watch Free on IMDb TV on the prior episode, it says it's not available on IMDb Freedive. When I access the 3-dot menu, and select the Amazon Prime option, it shows a combined episode for parts 1 and 2.
