Alan Moore is celebrated for his fine ear for dialogue, a trait which is displayed in this volume. Character speech patterns are differentiated with care. Jason Woodrue, a genius botanist, speaks and narrates with an advanced vocabulary and sentence structure. Meanwhile, monstrous Swamp Thing speaks slowly in monosyllables, the slowness of his speech demonstrated by constant ellipses in between words. This slow speech is not only done in the tradition of classic monsters like Frankenstein, it shows that Swamp Thing is struggling to retain Alec Holland's humanity, as human speech is difficult for him.
