- Bowman returns to the Discovery One with Poole's body. Hal won't let him in, claiming the mission's too important for him to let Bowman muck it up. He reveals he read their lips during the conversation in the pod. Bowman says he'll go in through the emergency airlock. HAL notes that without his space helmet—which Bowman left behind in his hurry—he'll find that very difficult. HAL has the best lines in the film, by a long shot.
