I have a theory (and this may have already been thrown out there) that Candace is a paranoid schizophrenic. However, she has never been diagnosed, and therefore put on any medications or sent to a special "school" for her problems. This explains the Zebra. Also, it could explain her need to constantly bust her brothers; she has several voices in her head telling her that what they're doing is some kind of devil magic or something. She just doesn't explain that in her busting attempt because another voice tells her that if anyone else knows about her brothers' demonism, something bad will happen.

... Yeah.
