Instead of feeling dread and fear at the betrayal of trust from Atlan, Ninth and the rest of the team felt hope.
They should be wondering if Atlan was even a human being at this point. After all, he was able to have more than one LifeSkill and all of his LifeSkills had the power to wipe out an entire horde of Canzers all by himself.
It was a fearsome kind of strength, something that would make a human wonder if he was still a part of their race, or simply someone that was pretending to be one.
But in these dire times, Ninth and the others couldn't help but put their trust and their faith in Atlan.
He could have let them die. If he wanted to keep his secret a secret for a long time, then he could have let the dragon kill them so that there wouldn't be any witnesses as he revealed all his powers to fight the dragon for survival.
