Turns out that walnut is the Cabal slang for pituitary gland. After torturing a victim to enlarge the gland, they insert a hook thing up the nasal cavity to extract it and then eat it.
I wonder if they could reach a certain degree in their order by having their own pituitary removed, knowing that this makes them dependent on consuming the organs from human sacrifice victims? This would explain the black eyes because the surgery technique has to choose one side of the sinus to use to access the bottom of the brain box.
This video describe one of the video rips in the Frazzled folder on Weiner's laptop. In it they sacrifice a young girl and then extract something called a walnut from her brain by sticking a hook tool up in her nose. The walnut is then divided between the two participants. This is consistent with a pituitary which has two parts, anterior and posterior.
