If Crispy spares him, Chewy can run away scot-free by sacrificing Crispy. But if Crispy sacrifices him, Chewy can keep one of his limbs if he also sacrifices Crispy.
Si Crispy lo salva, Chewy escapará ileso porque Crispy se sacrificará, pero si su amigo lo sacrifica, Chewy conservará un miembro si también decide sacrificar a Crispy.
