[Theory] How Hans is cooking the victims.
One thing that sticks with me about the lore of Hans; he's described as making crunching sounds behind his mask.
Not chewing. Crunching.
So I got to thinking, "Okay, so how is Hans cooking the people he kills then? Is he making pork rinds? Is he eating their bones for some reason?"
Then it hit me. Hans and the Metzgers came from Germany.
(Fun fact: Metzger is German for butcher!)
He's making them into Schnitzel. He's frying them. And the parts he can't make into proper cutlets? He makes popcorn style bites.
(Fun fact 2: German immigrants to America introducing this version of preparing meat is how we get chicken-fried steak)
