I no Caroline's last name is 'Black', because the other day i was watchin the old WAH eps, (cos I've got all 3 series on dvd, cos I'm cool like that lol) and I saw the one where Caroline comes to Africa for the first time and Fatani calls her 'Mrs Black'.   (lol, I had forgotten how funny and cute Caroline and Dup were when they used to fight with eachother LOL! and how Dup got really jealous over her because of Gerald! Aww Bless! Haha!!)

Also in series 3 when Dup and Caroline try and 'borrow' a male cheetah from Mara Caroline introduces herself to Ungala (the fence guard) as 'Caroline Black'.
