There was a part of Walker that was thinking about how he would reprimand Ventus when he returned. Especially since he was sure that she had no idea how different this way of thinking was from a human's thoughts.
No human would just say, hey, I am in charge of this child, watch them for me while you go off on a longer journey to a city i've never been to. Bit for a dragon, a longer journey could be the same as a small nap. Their sense of time and distance were radically different from the other races.
Tobe fair, this was still a step up. plenty of the dragons had tossed their young from their nests if they were not strong enough in the ways that they desired them to be. Whether it was affinity or not, a child like this hatchling that had a strong wind affinity with a lower light affinity would be disliked.
