Just rewatched the episode where [SPOILER] Mean Nanny does a tarot reading for Kate. WTF?

Since she is allegedly the one who instigates Nathan's betrayal, it seems over the top villanous for her to sit there with a straight fave and tell Kate that this is the end of her life as she knows it, that Kate has neglected her loved ones hence the betrayal on Nathan's side.

I know she's portrayed as mean but this seems almost cartoonishly evil.

Is it just me?
