Leandro was glad that Aisha was compassionate enough to put a stop to the banishment of the Gatekeepers' families. Though, he felt bad for her for experiencing such negative treatment by his own people.
However, he couldn't blame them. It has been centuries that Gaea hasn't encountered a human species. It is normal for them to be wary of her.
As soon as he heard how Aisha was being treated, he immediately left the Chancery. He didn't think that Aisha would go out of the towers at once. He thought she would familiarize herself first within the Castle walls, where it was safe for her.
He gazed at Aisha, who was furious right now. As much as he wanted to agree with her, he must put things in order.
If he allowed the Gatekeepers to be free, everyone would take their duties lightly. And there is no great or small duty in the Castle. Being responsible no matter how small a task is contributing to people's safety.
