Sarah slipped in the yellow blood from the dead seeder worm and falls head first next to Melody. She has only a moment to think before Melody's eyes roll back and the whole worm comes squirming out of her with a surprising agility, but the engorged monstrosity has trouble fitting its whole bulk in quickly.
The campus security guard arrives on the scene. He is a large and out of breath man, wielding a taser. He sees the half of the worm still sticking out of Sarah and seems terrified.
