So when Camomile walked...
 

how exactly did they deal with it? They kept Rachel and chose the next highest which was Keeley and Corin joint? I assume it's that.

Of course I've thought maybe they made the housemates re-nominate? Just that Camomile nominated and then proceeded to walk... so if they didn't re-nominate then Camomiles' nominations still stand... and what if one of her two if not both of her nominations are of the three now up for eviction? Then that would be very unfair on Corin and/or Keeley and/or Rachel.

Anyway, how was it dealt with?
