I do like dorinda but she has had some really appalling behaviour when drunk, not falling over, repeating herself etc. Like sonja. But saying really cutting, unnecessary, aggressive things. E.g. Tinsley and the aid trip with Bethenny. I wouldnt be surprised if she got even more voracious off camera, (to the point production don't want to be responsible for/associated with it), also it might not just be alcohol (bethenney alluded to dorinda's ex boyfriend being big into coke so who knows). I hope whatever it is improves and she comes back, she's a real character.
