One of the Devas had run off. They never did that, which was exactly why it scared Gundham as much as it did. Sure, they'd told him before that they got restless, but he didn't expect San-D to jump from his shoulder and run off like he had. What if something happened to him? Gundham would never forgive himself if that happened. So, obviously, he'd given chase and, thank god, had found him curled up at the feet of a certain someone, who was happy for the hamster's company.
