General Yaddy did exactly what he said he would: making a report to the main base of the vampire corps unit on Earth. He thought he would need to do this as quickly as possible to get a response about what to do next.
However, what he did refrain from in his report was about the troublesome vampire whom Jessica was currently travelling with. He had debated with himself what to say, but no matter how he phrased it, Yaddy felt it would make him look reckless, and it might show him as an erratic leader who couldn't handle the situation.
Many members in the Corps were after his position, mainly the vampire Corps Generals on other planets; this was because, in a way, being the leader of the vampire Corps unit on Mars made him the Number Two in the vampire Corps, and if he were to report about Quinn, his rivals would make sure to take advantage of the situation.
