Shane was not too keen in helping Aisha, a fact that she probably knew. He only wanted to let his aunt know that he was doing fine and had returned from the expedition with all his limbs attached.
Otherwise, if Aisha were to tell his aunt that five students had met their deaths without naming them, Aunt Kia would probably go frantic and he didn't want either Aisha or his aunt to go through that..
Shane, who knew Aunt Kia since the day he was born, had only witnessed it once and it would have been a lie if he were to say that he had not found it both shocking and terrifying on that day, several years ago.
Compared to his father, Aunt Kia was not as obsessed as him with fighting and expanding humanity's territory, wealth, and political power.
Instead, she was more interested in getting to know more about the Primordial Dimensions, other races and everything that was even remotely related to mana.
