Well, looks like I was overthinking. Bartlett pulled his broadsword up from the sand, ready for battle.
"Duke will devour you, small creature, and crush your skull fully in his mouth!" The first head to speak licked its lips, "Duke loves the taste of brain. Best to roast the entire skull over a fire, until the brain juice boils. Then smash the skull, sprinkle with salt, chili, pepper, and celery. It's a divine taste – slippery, soft, steaming hot. Really delicious!" A steady stream of saliva dripped from its mouth.
Uh huh, it seemed that the head with the red facial markings had quite a knowledge of 'eating'! Couldn't help but admire it a little, Bartlett thought.
"No, Carter wants to eat the brain!" The other head protested vehemently.
"Duke is smart, he wants to eat the brain; Carter is dumb; he can only eat the butt!" The head with the red facial markings seemed to be the dominant one.
