Horo became certainly jealous when the magician was revealed to be a beauty (I think that's why she said the magician is the kind of person she hates). Those two have a peculiar kind of a relationship in any case. Horo can make Lawrence do whatever she wants by pushing a little. That makes me think Lawrence wouldn't mind if things went a little further between them, but at the same time I suppose at some level he tries to keep a certain distance because they are a wolf and a human in the end. Or at least he isn't actually pushing forward like he probably would if she was a normal girl.

But Horo sure likes delicacies...
