Surprisingly, Nicola does have a child, see here. I say 'surprisingly', as you rarely, if at all, hear her mentioning him, although maybe that could be down to editing.
I'm not surprised about Carly going, she didn't have a lot to say for herself. DVD reminds me a lot of a certain actor who boldly goes where no man has gone before. He also, apparently, doesn't endear himself to the likes of George, for instance.
Don't know who could be next out. It's usually the quiet ones. Brian? Simon?
