Avrum was initially nervous about teaching Kyran, a genius unlike him, about poison magic. However, he was pleasantly surprised to find that Kyran was remarkably down-to-earth when learning something, a quality that made him more approachable than Avrum had expected.
Kyran was not afraid to ask questions that might sound stupid to others, nor was he timid about requesting Avrum to perform magic that others would find absurd.
In the end, it was not just Kyran who grew from the learning experience; Avrum also underwent significant growth, which he did not expect but welcomed nonetheless.
