You know, I seriously wish an emotion-feeding being - preferably someone we know, like Scatty - would consume some of my emotions; I could certainly use it.
Anyways, I'm not sure about the Witch's diet. We have not seen her eat humans yet, but she does like to shrink them. We know she does it to those who anger her, but doesn't it seem a little harsh? Also, I wonder what will happen to the guy in the glass paper weight.
