Rebecca saved herself in the boardroom (IMHO) - she fought for her life, and I (like her) wondered why she had been brought back when others were equally bad for other reasons.
Michelle herself said on YF that she brought Rebecca back in because she thought she would go rather than her because of the low sales, so it must have been quite a shock to find herself out the door.
I agreed with her taking Alana in as she made a pigs ear of being sub team leader, but I'd have taken Natalie who sold the pricey vases for next to nothing, or the one who sold the expensive Ekornes chair for a pittance, rather than Rebecca.
That said - I did think Rebecca was useless, but she was the only one on the sub team who picked up that the pricing of the goods matttered, when none of the others did (or cared), so was marginally less useless than some of the others......
That Indian girl is a snake in the grass - dropping everyone else in the doo door to make herself look good!
