Is season 12 still airing? If not, it's ended without a reunion. Nicole is just odd. I'm sure she's simply trying her worst to be kept on as a regular, but she's like a child caught red handed who still denies doing it.
I appear to have seen them all then (I was sure I had missed out a fair few of them), so I'll be giving at least the debut season another airing at some point soon just to appreciate retired icon, boxy Mugali back on the box.
