Listened to this episode recently, and the "what did we learn today" segment struck me as... not quite odd, but missing the obvious reason why Eva Draconis was doing all this in the first place. Or lack of reasons, rather.
Psychosis does not have internal logic supporting its actions. A malfunctioning brain does what it does, regardless of what a (comparatively) healthy mind might try and guess at. Eva Draconis is most likely INCREDIBLY mentally ill. To her, she's simply recounting reality. To the rest of us, she's completely off her rocker and hallucinating Hamish tossing her around like a poltergeist with a ragdoll. Any perceived expression of creativity or selection of tropes/characterizations for Hamish is more akin to looking at a Rorschach Test than reading a biography.
I dunno. I found the episode interesting to listen to in the same way it's interesting to read about Gene Ray discovering what biracial people are. The final segment was more of a curveball when listening to it, like "Do the hosts know that mental illness doesn't really follow any sort of rules?"
Also while listening, I think (like 75% sure) Hamish is a literal sock puppet filled with whole hard-boiled eggs, according to Eva's descriptions. (10 peanuts to the person who draws that)
