En route to their next target (the Veil Nebula), the "Dark Star" is hit by a bolt of electromagnetic energy during a storm, resulting in yet another on-board malfunction, with "Thermostellar Bomb #20" receiving an order to deploy. With some difficulty, the ship's computer convinces Bomb #20 that the order was in error, and persuades the bomb to disarm itself and return to the bomb bay. Talby notes the malfunction, and decides to investigate the fault (to the complete disinterest of his crew mates), and discovers a damaged communications laser in the emergency airlock while the crew is engaging their next bombing run. While attempting to repair it the laser malfunctions, blinding Talby and knocking him unconscious, inadvertently triggering a more serious problem, causing extensive damage to the ship's main computer, and damaging the bomb release mechanism on Bomb #20.
