Gael tried to contact Haylee again but failed. After which, he reached out to Lira. But when he also failed to connect with her, he tried contacting Fiona. When that failed again, Gael started to feel indignant. It made him feel that they were doing something behind his back. Of course, he only felt that way about Lira and Fiona.
Since he could not contact them directly, Gael entered the army's main channel and tracked the army's recent activities. Prior to that moment, he could not connect to the army's main channel due to a lack of signal. The tower in Noser had long been destroyed and if not for the arrival of the army, which always had a mobile tower, he would not be able to connect.
