Davinia is a wealthy (socialite trustafarian), gullible, idiot with a lot of followers. She was in Hollyoaks when it first started, before she started all this woo guff. It wouldn't be a problem if it was just her and her nutty friends talking to themselves, but because she is a z-lister she has a following that hang on her every word, regardless of whether it makes any logical sense. Some of it is just stupid people saying stupid things but some of it (like the skin cancer stuff) is plain dangerous.
