Bomb 20 lowers from the ship and the Computer tells it to return to the bomb bay. Bomb 20 at first refuses to return until the Computer does a manual override. Later the bomb bay opens up and Bomb 20 lowers once again from the bomb bay doors. The Computer tells it to return again and Bomb 20 returns once more. The Dark Star arrives at the rogue planet and release the bomb bay door and Bomb 20 lowers from the belly of the ship. Sergeant Pinback tries to release the bomb, but it fails to drop. Lieutenant Doolittle communicates with Bomb 20 and tells it to disarm, but it refuses. Doolittle puts on his spacesuit and leaves the ship to speak with Bomb 20. He asks Bomb 20 how it knows that it truly exists. He then continues asking it questions. Doolittle convinces Bomb 20 to return to the bomb bay. Pinback tells Bomb 20 to disarm, but it calls him false data. It then detonates itself, causing the ship to explode.
