The company had made the Ood subservient by removing their secondary external brains and by placing a circle of energy pylons around the Ood Hive mind, This acted as a telepathic inhibitor. Halpen's personal Ood, Sigma, had been dosing Halpen with a solution mixed with hair tonic that transformed him into an Ood.
The Tenth Doctor and Donna shut down the telepathic inhibitor and restored the Ood's ability to "sing" telepathically again. The Ood song called out for all Ood off-planet to return home. With the Ood free and most of the company's staff dead or fleeing from the Galactic Police, Ood Operations was shut down and the base was abandoned, allowing the Ood to be free and live naturally again.
