I've been thinking the same thing for a few drunken episodes now. I think of the Sonja who was introduced on the show during the Scary Island season and how classy she was, how she didn't want to gang up on anyone but was just calmly waiting for her pedicure. Then suddenly she gets blotto a few times and comes on to LuAnn and Bethany and it's like it's her 'personality' on the show. It gets her attention to be the one everyone's taking care of, stuffing back into her bikini (or Bethany's) or upset about because she fell on a glass table. Not saying she's not a drunk at times, but I think she really ramps it up for the show.
I honestly thought it was all real until one episode where she was slurring, doing her drunk thing, and as everyone moved away and left her and Tinsley alone she changed into mean, nagging Sonja instantly and had to school Tins on how she should act. Then the minute she's around the others she smoothly morphed back into slurring good time Sonja! I've been giving her the side eye now for a couple of seasons. She has no storyline except the drunk one. And I think Leah watched the show and decided SHE was going to be the outta control falling down drunk one now. So not interesting to me at all.
I do think Dorinda is a mean drunk who hates her life and takes it out on people like a true bully. So obvious that she viciously attacked Tinsley for several episodes, Tinsley leaves, and suddenly she's after Ramona in the same loud foghorn voiced way. NO interest in her anymore either and I loved her in the beginning.
That was a gross Halloween party and not in the expected gross way. The food was awful, disgusting! I think Luann didn't protect Ramona from Dorinda because she was miffed that Ramona brought Missy to the party when Ramona knows Lu doesn't want to be around her. It was a tacky thing to do and planned in my opinion. (probably by production)
