I've noticed over the last few weeks that Dan and Nadia have been hanging around together a lot - they seem to have become firm friends

Not only that but they have a sort of flirty relationship. Shell was keen on Dan anyway and now Michelle seems to like to tease him too, in fact when she's not alone in the bathroom/spa/bedroom/wherever smooching with Stu, she's with Dan and the other girls.
Could this be the new harem?
