I think Shabby is excellent.
She is stimulating, lively, bouncy, articulate and although quite emotional she is rational, logical, perceptive and intelligent with it.
Her language is concise, direct and amusing.
Her complaints to BB about being warned were particularly incisive and amusing, "they could have just given me a warning" was one of her best lines delivered with dramatic intonation.
Initially I thought she was just someone who projected a zany character for effect and attention, but she does seem to be genuinely zany and striving for drama and stimulation in her life.
Go Shabby!
