Very similiar aren't they? Both came in loud, argumentative, disruptive. Both got a warning from Sugar to tone it down, both took this on board and toned down,both got a kind, gentle 'with regret' firing. Finally on the series 3 ';why i fired them' Sugar said that he was sure Jadine went away having learnt a lot, he said the same thing about Joanna

Yes I noticed a resemblance there as well.

They both made a teary but dignified exit and shared similar journeys on the show.

They were both the winning PM in the first task too, I think.
