I kind of want to settle on this read, and the thing that jumped out at me was also his weirdly small head. The trophy skulls everywhere look regular size, though. If this is a head-shrinking bit, that seems incongruous.

I don’t have other ideas though, beyond “fat man on his way to get eaten”… which I guess is maybe enough. Sometimes they’re that simple. His head looks so weird though, I want it to mean something.

Edit: I think Lux has it. He’s shrunken his own head to make it an undesirable trophy.
