Aaron, like many others from Rock City, was drafted into the Exploration team. Even Mary was part of this Exploration team.
Though he knew her, he kept his distance.
One, she seemed to be in disguise, as she changed her hair colour.
Second, her last name didn't seem to be what he remembered from the school.
When he heard her name from the official, who was taking note of all that would be going on this exploration, he was confused. For a second, he wondered if he remembered it incorrectly, but then it hit him.
She was here incognito.
If the people knew who she was, they would be swarming her. She, after all, awakened a SS-Rank Class, but no such thing was happening, which means no one thought that she was who she was.
So, he didn't try to interact with, afraid that someone might be keeping tabs on her, and he didn't want their attention on him, at least not now.
