Hey, by the way, Meg, we both have earrings, so let's just sit quietly and not say anything.
So, I suggest we calm down! I think it was just someone who couldn't sleep and decided to take a walk around the castle. I just looked out to see who was knocking – and at that moment, some silhouette completely disappeared near Kyle's chambers. Probably went further... but I didn't feel like chasing after him.
Although, it's all just silly speculation.
