"Now, is there any question?" asked Angus towards the others.
After showing his strength in front of everyone, Angus became sort of their leader. This is also fundamental knowledge when forming a team in Firuman. The strongest person usually will become the leader and decision-making person.
Unless there is some dispute or conflict with the leader, everyone usually just uses this way to select the leader. Then, the team member will reselect another leader if there is more problem in their leadership after a few confrontations.
In the case of the Angus team, everyone already knew and trusted Angus, so they didn't mind Angus taking leadership, especially after Angus's act to push back King Leon.
After looking, there is no question. Angus immediately tells the others to move out. He could feel more monsters coming towards their place because of the space fluctuation from the portal.
