Since the young lava dragonet only came at night, they have free time till then. Jeanny suggested they explored deeper into the cave so that they knew the terrain better before tonight's capture mission, but Peniel advised against it.
The huge cavern hall where Jack last saw the young dragonet might be close enough to the dragonet's nest already. If they went there and allowed their presence to be found out by the adult dragonets, then they could kiss this capture attempt goodbye. Those dragonets would become alert and pay attention to them. The fact that none of them had yet to come means that this young dragonet did not inform its parents of its finding.
Everyone separated into small teams like yesterday and farmed the flame drakelings. Jeanny reminded everyone to come back before sunset. They needed to rest and be fully ready for the capture mission.
