Phillips' main attention had been on Lance and Charlotte, so when he heard Austin shout for Grice to jump into the lake to commit suicide, he instinctively stood up before sitting back down, knowing his son was a Giant Dragon and wouldn't die from jumping in the lake.
He had also been paying some attention to his son interacting with the Black Dragon Youngling. Initially, when Grice put on the Black Dragon Youngling's Music Shell, everything seemed normal. After a while, however, his son's emotions became extremely unstable.
It wasn't long before his vertical pupils even turned red. At that moment, his attention shifted to the Black Dragon, specifically, he was captivated by the Black Dragon's arrogant words from earlier.
Wanting to enter Black Dragon Island, the Black Dragon didn't wish to be tested by Dragon Island and even made bold claims, saying it would fight its way onto Dragon Island.
Does the Black Dragon imagine Dragon Island as merely a slightly bigger island?
