Gregory has become very mistrusting of his son after he returned home from service, following his court-martial; in particular, not allowing him to go anywhere near fire arms. It was also his wish for Simon to remain at the orchard and work there instead, though his real reasons for it was that he actually missed him being around.

Gregory continued to run the Dodds Orchard during the Pandoran War, working to keep the business, workers and Sally safe from the influx of refugees arriving at Earth.

Simon contacted him on Christmas Day, 2624, after not speaking to his family for two weeks. Gregory had initially thought that his son was dead, but was grateful to see him alive. He confessed to Simon that, while defending the orchard, he had shot one of the men who had been attempting to steal the trucks. He did not mean to injure to robber badly, but suspected that he had actually killed him. He felt terrible about the action and told Simon that he thought he would probably never forget it.

After the conclusion of the Pandoran War, Gregory ran the orchard for a number more years, before finally retiring due to arthritis.
