The healers said it was trauma. Perhaps he was too young, or too sensitive; perhaps it was only that it had happened in such a way, at such an impressionable time – in any event, Lan Wangji’s reactions to his mother’s death had gone well beyond the normal signs of grief and turned into something much more severe.

From not being around the place where he was drowning in the memories of his mother. They sent him to the Jiang Sect.
