Henrietta is a big foodie when she's hungry and the tribe knows it. That's why they don't mind being used as a meal to fill their queen's hunger if she needs big meals to end the emptiness in her womb.
What could be better than to satisfy this hunger than to eat the members of the tribe who are the biggest in order to have a full stomach.
Thus, Henrietta can relax, with a belly filled with large voluntary prey that moves a lot, all being satisfied to be in the belly of their queen, serving as food.
(Fortunately, they will reappear later, but having lost all their fat, having sacrificed it to fatten their queen.)
